-> ''"The task of producing a cpr-themed cover version is left up to you, gentle readers, talented readers, readers who have discovered that if you hover your mouse over comics on the internet, sometimes they tell you to do stuff."''
--> -- Webcomic/DinosaurComics [[http://www.qwantz.com/index.php?comic=1426 March 11th, 2009]] alt text

Text that shows up as a tooltip when you hover the mouse cursor over an image -- or other elements on a page, even text -- also known (more accurately) as "title text". Alt text has many uses; some {{Webcomics}} use it to display comments, credits, or [[OneTwoPunchline additional punchlines]]. Wiki/TVTropes does have [[SelfDemonstratingArticle Alt Text]] capabilities, in the form of the PotHole.

Finishing a lengthy ArchiveBinge, only to find out you missed all the funny alt text, is something that hopefully will never happen to you.

Alt text is inserted by defining the "title=" attribute of the image in the webpage's html or xhtml document. The ''actual'' "alt=" attribute [[http://en.wikipedia.org/wiki/Alt_attribute has other purposes,]] though older versions of Internet Explorer would still display it as a tooltip, leading many authors to create alt text only functional in it.

Firefox 2 tended to truncate the displayed alt text, although [[http://piro.sakura.ne.jp/xul/_popupalt.html.en there's a plugin for that.]] This was fixed in Firefox 3.6.

%% Administrivia/ZeroContextExample entries are not allowed on wiki pages. All such entries have been commented out. Add context to the entries before uncommenting them.
* ''Webcomic/{{Achewood}}'' added alt-text in fairly early in its run.
* ''Webcomic/{{Chirault}}'' starts using alt text at some point, but it's usually not really funny or interesting.
* ''Webcomic/DearChildren'' has alternate text on many of its pages, and they are almost always humorous.
* ''Webcomic/DinosaurComics'' has an additional punchline in the alt text, as with the comic's archive name and email subject.
* ''Webcomic/TheEnd'' has started running stories in the alt text. Chapter 15 told the story of a studio team making a movie tangentally similar to the chapter. Chapter 16 does something similar to old pulp sci-fi novels.
--> Our intrepid heroes have scarcely begun to explore when their way is barred by the one of the Cosmic Mind-Thief's evil obstacles - the first of many, no doubt! "Look out, Savage! The Mind-Thief has constructed an id fence to bar our way! One touch, and your consciousness will be overtaken by your innermost fears!" "Not to worry, Smart! I still have the Cowl of Solitude that Science-Commander Warner gave me! It will isolate my thoughts in a psychic echo chamber-" "-and short out the id fence, overloading and destroying the psi-crystal that powers it! Of course! You're sure putting that doctorate in Psychophysics to good use, old friend!" [[note]]None of that is accurate at all to the actual comic[[/note]]
* ''Webcomic/ExistentialComics'' has alt-text on most (but not all) comics, typically a second punchline. More "serious" comics, the early issues, and some at random don't. Humorous is also provided for most of the philosophers listed at the bottom of the page -- clicking on their names leads to a page listing every mention of the philosopher in the comic.
* ''Webcomic/FurryExperience'' adds alt-text starting on Thursday 17 December 2009, though it's done about half the time, while the rest go alt-text-less. It's usually included to add something without the characters BreakingTheFourthWall.
* ''Webcomic/ImprintChronicles'' has alt text which is often the 'biggest' sound effect on the page, or a very short comment on a character or panel.
* ''Webcomic/IrregularWebcomic'':
** Author David Morgan-Mar argues against them in [[http://www.irregularwebcomic.net/1640.html this strip,]] a parody of xkcd. While using it anyway, because he's parodying ''xkcd'', and wants to get it right.
** His [[http://www.irregularwebcomic.net/1458.html previous xkcd parody]] featured a TakeThat against alt text ''[[HypocriticalHumor in the]] alt text'', which read "Some text that's too long to display when you mouseover it in Firefox, thus forcing you to check the source code to see it". Which, of course, shows up as "Some text that's too long to display when you mouseover it in Firefox, thus forcing you to..."
* ''Webcomic/{{Oglaf}}'' initially didn't utilize alt text as bonus info, but progressed to use alt text and later on to simultaneously using different ALT and TITLE text, making some people having to not only hover their mouse over the image but also look up the alt text in the source of the page.
* ''Webcomic/{{xkcd}}'' alt text is perhaps the most famous of the "extra punchline" genre; read the comments on the above fix for Firefox 2, and you'll find xkcd readers seem to be its primary market.
** The ''Blog/WhatIf'' spin-off blog initially didn't have any, although this changed soon after. Initially all the tooltips were simple descriptions of the images, but somewhere between [[http://what-if.xkcd.com/19/ "Tie Vote"]] and [[http://what-if.xkcd.com/28/ "Steak Drop,"]] they, too, became extra punchlines.
%%* [[http://xawu.thecomicseries.com/ Xawu]]
* ''Webcomic/TheAdventuresOfDrMcNinja'' has done this since the [[http://drmcninja.com/archives/comic/2p1/ So What Is a McNinja]] issue, mostly for another joke or some commentary on the strip.
%%* ''Webcomic/TheNonAdventuresOfWonderella''
%%* ''Webcomic/GoodbyeChains''
%%* ''Webcomic/ThinkinLincoln''
%%* ''Webcomic/{{Overcompensating}}''
* ''Webcomic/WooHoo!'' has additional punchline alt-text on every page.
* In ''Webcomic/KoanOfTheDay'', a last thought is always given in the hover-text.
* ''[[http://www.oafe.net OAFEnet]]'' reviews begin with straightforward alt text naming the subject of the review, then quickly degenerate into name-calling, in-jokes and even running gags. Yes, alt text-only running gags.
* While it is, perhaps, not exactly this trope, ''Webcomic/{{Narbonic}}'' features hidden text in the file name of each strip: a word or words that, when placed in order by date, form a side story.
* ''Webcomic/{{HERO}}'', ''all'' the text (except one chapter, for stylistic reasons) is in Alt Text. Dialogue, narration, everything.
%%* ''Webcomic/ASofterWorld''
* ''[[http://threesummersstrong.thecomicseries.com/ Three Summers Strong]]'' warns the user that there are Alt Texts in its slogan, so that the reader knows they are part of the joke.
* ''Webcomic/MoltenBlade'' makes frequent use of title tags to include [[ShoutOut references]] and comments in strips that are otherwise intended to be serious.
* ''Webcomic/SaturdayMorningBreakfastCereal''
** The comic didn't use to have alt text but instead had and has a functionally similar votey comic, where mousing over (later clicking) the red button gives an extra picture with an extra punchline. It's like alt text for people too lazy to read. (But you still have to visit the website and thus give him ad hits. Clever.)
*** The first few years didn't have votey comics, but the author starting going back and adding them. Several are about how he doesn't get the joke he wrote over ten years ago.
** In 2015 or so, it gained alt texts as well, which sometimes contain a joke but sometimes just name the comic.
%%* ''Webcomic/PicturesForSadChildren''
%%* ''Webcomic/DaisyOwl''
* Thinkgeek, being a geeky store, used to hide little jokes in the thumbnails on the gallery pages. They've stopped doing that, though.
%%* ''Webcomic/{{Girly}}''
* ''Webcomic/{{Suppression}}'' has some truly great Alt Text, such as [[http://suppressioncomic.com/?p=133 here]] and [[http://suppressioncomic.com/?p=162 here]].
* ''Webcomic/SomethingPositive'' has little comments similar to alt text printed in plain sight at the bottom of the comics.
** As does ''Webcomic/MultiPlex''
** So does [[http://imprintchronicles.com ImprintChronicles]], with snarky comments left by the creator.
%%* ''Webcomic/GastroPhobia''
* ''Webcomic/TheNoordegraafFiles'': All the pages have it. Sometimes it's a joke, sometimes a reference, and sometimes it's just commentary.
* ''Webcomic/KnightsErrant'' frequently has amusing comments hidden in the alt text.
* ''Webcomic/{{Housepets}}'' often uses the alt text as a secondary punchline for the strip.
* ''Webcomic/AmazingSuperpowers''. From comments:
-->- alt text=win\\
- How do you see an alt text?\\
- The only appear to those who truly believe.\\
- Those that believe in MOUSE HOVERING.
%%* Webcomic/TrueMagic: [[http://www.true-magic.com/view.php?id=1 True Magic]].

** The [[http://flakypastry.runningwithpencils.com/comic.php?strip_id=300 300th strip]] has a ''215-word'' alt text.
* ''Webcomic/{{Wondermark}}'' uses its alt text as a secondary punchline, which is sometimes funnier than the first one.
* [[{{Pothole}} TV Tropes]], as mentioned earlier. %%Like many other examples, there are multiple layers.
* ''Webcomic/ElGoonishShive'' once featured a hidden line in the image name between 2006-02-22 to 2008-02-22. They have been lost since the comic moved into a new php-framework but can still be read ''[[http://www.ookii.org/egs/statistics/comiclist.aspx here]]''
%%* ''[[http://www.fantasycomic.com/ Chasing the Sunset]]''
* ''Webcomic/TheWordWeary'' has alt text in every comic. Whether or not it's actually funny.
* ''[[http://cowbirdsinlove.com/ Cowbirds in Love]]'', lampshaded in [[http://cowbirdsinlove.com/11 #11]]
%%* ''[[http://erikahammerschmidt.com/an/ Abby and Norma]]''
%%* ''Webcomic/JohnnyWander''
* Ever since ''[[http://www.out-at-home.com/archives/356 this]]'' strip, ''Webcomic/OutAtHome''.
%%* Chris Sims' [[http://the-isb.com Invincible Super-Blog]]
* ''Webcomic/BrawlInTheFamily'' does this starting with comic #167. Later {{Lampshaded}}:
--> - "Hey! Stop reading the mouseover text and look at the comic!"
** The author does not add alt-text to comics that involve especially long and deep stories, allowing the reader to enjoy the comic as it is.
%%* ''[[http://community.livejournal.com/dante_res_comic Dante Residential]]''
%%* ''Webcomic/FurthiaHigh''
%%* ''Webcomic/{{Concession}}''
%%* ''Webcomic/{{Nedroid}}''
* Non-webcomic example: the [[CosmeticAward awards]] in ''[[VideoGame/QuakeIIIArena Quake Live]]''.
* ''Encyclopedia Dramatica'' uses potholes much the same way.
%%* ''[[http://cuteoverload.com/ Cute Overload]]''.
* The [[http://hanna.aftertorque.com/?page_id=2 cast pages]] in ''Webcomic/HannaIsNotABoysName''
* ''Webcomic/TheWayOfTheMetagamer'' not only has title= text, but has a character to ''read'' the title= text. The first presenter was [[ThemeNaming Titular]], replaced later on by [[PunnyName Ebony Nauss]].
* ''Webcomic/SkinDeep'' started adding them from the ''Exchanges: Heartaches'' storyline onwards.
%%* ''Webcomic/TwentyFirstCenturyFox''
%%* ''Webcomic/WorstOfTheTimeLords''
* ''Webcomic/TheDawnChapel'' often uses hovertext for both the comic itself and the accompanying 'stinger' process sketch.
%%* ''Webcomic/EverydayHeroes''
* ''WebComic/OzyAndMillie'' used mouseover text on the ''cast page'', featuring quotes from the characters.
%%* ''WebComic/{{Precocious}}''
%%* ''WebComic/RustyAndCo.''
* ''Webcomic/AbstruseGoose'' has mouseover Alt Text and an alternate title hidden in full text of the image location (found by viewing the image info).
* On the news site ''[[http://japanator.com/ Japanator]]'', Ben Huber's ''Manga/{{Yotsuba}}'' comics have alt text.
%%* ''{{monospace}}''
* ''Webcomic/FiveColorControl''. The first comic {{Lampshaded}} it, with alt text reading, "[[HypocriticalHumor Sorry, we're not cool enough to do rollover jokes.]]"
* ''Webcomic/{{Selkie}}'' sometimes does this, calling it "Secret Director Commentary".
%%* ''Webcomic/LnM''
* ''Webcomic/BicycleBoy'' has Alt Text in almost all comics.
* ''Webcomic/FarOutThere'' has been featuring Alt Text since [[http://faroutthere.smackjeeves.com/comics/1092837/page-315-good-company-is-so-hard-to-find/ page 315]] (on the Website/SmackJeeves pages, at least)
* Michael Poe's Webcomic/DoesNotPlayWellWithOthers, as well as the newer strips in his Webcomic/ErrantStory.
* ''Webcomic/DownTheStairs'' features Alt Text in all comics.
* ''Webcomic/MiscellaneousError'' uses Alt Text for additional punchlines.
* ''Webcomic/{{Paranatural}}'' strips usually have Alt Text, though it's absent from some of the earlier pages.
* ''Webcomic/{{Homestuck}}'' doesn't ordinarily contain Alt Text (it would be highly impractical for its format), but a few updates [[http://www.mspaintadventures.com/scratch.php?s=6&p=005956 starting here]] incorporate Alt Text in the banners. The Alt Text serves as the AuthorAvatar's voice [[ItMakesSenseInContext while he parades through the banner in a quest to find the guy currently narrating the story and wrestle the narrative back from him]]. [[spoiler:And then, starting [[http://www.mspaintadventures.com/scratch.php?s=6&p=005976 here,]] we get to hear [[BigBad another character]]'s voice for the first time. This is completely terrifying.]]
%%* ''ExtraOrdinary''
* ''Webcomic/TwoPStart'', although the alt-text only begins mid-way through.
* ''Webcomic/AlfdisAndGunnora'' has Alt Text on every page, usually a commentary on the page or characters, occasionally additional dialogue.
* ''Webcomic/TheOrderOfTheStick'' doesn't have actual Alt Text, but the comic titles often serve the function of the additional punchline, only making sense to the reader after the page in question has been read. The archive binger may be somewhat confounded, however, by the fact that the comic title doesn't display from the comic page itself, though the newest page title is always visible on the sidebar.
** Comic titles are visible in [[http://www.giantitp.com/comics/oots.html this archive.]]
* ''Webcomic/{{Chainsawsuit}}'' is another unusual case. A secondary punchline or remark can often by found by checking the list of search tags under Kris's rants. To name a few:
-->thems ain't worth a trip downtown
-->she's acting all mad but she probably likes him i bet
-->the letter y is different in english
-->ho boy wot guacs
-->this is the only comic with the tag samsung galaxy tab
* ''Webcomic/EdmundFinneysQuestToFindTheMeaningOfLife'' has a little paintbrush icon under each comic, which displays the alt text in a little widget if you hover your mouse over it. Apparently the alt text is stuff Edmund writes down in his notebook.
* ''Webcomic/GunnerkriggCourt'' doesn't technically have alt text, but the witty little comments below each comic serve the same purpose, and are just as easy to miss the first time you read it...especially because they don't start showing up until around chapter 5.
* ''Webcomic/LsEmpire'' has some where the alt text for multiple pages need to be read in order to get the joke.
* For a non-webcomic example, some Website/YouTube users like to put an extra joke into their videos' tags, like LetsPlay/{{raocow}}.
* ''Webcomic/TeaHouse'' starts using this early in chapter 3.
* ''Webcomic/NewSchoolKids'' has this, though usually only tangibly related to the plot.
* ''Webcomic/HappleTea'' uses it on occasion.
* ''Webcomic/{{Thornsaddle}}'' has alt text for most of its strips, especially the earlier one.
* [[http://tcrf.net/The_Cutting_Room_Floor The Cutting Room Floor]], a wiki covering [[DummiedOut removed]] [[WhatCouldHaveBeen content]] in video games, often adds a silly joke to the images. Since it's a freely-editable wiki, the humor value varies.
* The [[http://www.askdreldritch.com/index.html Ask Dr. Eldritch]] comics includes the added punchline variety.
%%* ''Shinka: The Last Eevee''
* ''Webcomic/SidequestStory'' uses this trope for additional commentary and dialogue for its pages.
* ''Webcomic/AxeCop'', starting around comic #84.
* Almost all ''[[http://www.ddtcomic.com/ Dewey Defeats Tarzan]]'' strips have this.
* ''Webcomic/APTComic'' is currently trying to make sure every one has one.
* Website/ItHeSoftware does this from time to time, often to cram yet another ShoutOut in.
%%* ''Webcomic/StrongFemaleProtagonist''
* ''Webcomic/TheFoxSister'': Sporadically contains funny remarks about the respective page
* ''Webcomic/MSPaintMasterpieces'': Well, sorta. There was never text to begin with (he used filler for that), but then Dave set up DisguntledFerret's comic with a text function starting on #958 (it is only viewable if the comics are displayed one at a time).
* Equestrian themed webcomic ''[[http://www.theideaoforder.com/ The Idea of Order]]'' not only uses alt text, but also includes an [[OneTwoPunchline additional punchline]] in the caption. For the inattentive that means three passes through the archive.
* ''WebComic/{{Precocious}}'': Used mostly for LampshadeHanging (especially in regard to [[WhiteVoidRoom lacking backgrounds]], {{Spoof Aesop}}s, and incredibly JustForFun/{{egregious}} {{pun}}s).
* A variation in ''VideoGame/DistortedTravesty'', which uses GameMaker's ability to change the text in the title bar for each room to provide developer's commentary (or meta jokes) if the game's played in Windowed Mode.
* ''WebComic/DumbingOfAge'' started having it on February 14th, 2013. The first altext was, appropriately enough, "what i can add HOVERTEXT???"
** ''Webcomic/{{Shortpacked}}'' also started doing this. The text on both is often a secondary joke or meta explanations/warnings/information. The ''Webcomic/{{Roomies}}'' redux only has the strip title as hovertext; any additional info is put in the news box for that strip.
* The header images for abridged scripts at Website/TheEditingRoom all contain a mean {{pun}} on the film's title, the better for you to mock them with.
* ''WebComic/PoppyOPossum'' offers a second punchline or some commentary for each page.
* ''Webcomic/GirlsWithSlingshots'' has them (since #1054), sometimes as a second punchline, other times as an author's note.
** As of spring of 2014, there is an icon next to the comic navigation links which, when touched on a tablet, will display the alt-text, at long last making them accessible for readers using tablets or other mouseless formats.
* ''Webcomic/PrincessChroma'' has used alt text from the beginning.
* ''Webcomic/BiterComics'' features hover text either adding to the joke or offering some commentary on the work.
* ''Webcomic/GuildedAge'' uses alt text in every comic, even guest comics. Mostly it's another joke, though for the chapter beginnings it's instead "The one where [something related to the chapter contents]."
** Then there's [[http://guildedage.net/comic/chapter-34-page-24/ that one page]] with the ominous ''[[NothingIsScarier lack]]'' of AltText...
* ''Webcomic/{{Whomp}}'' started using alt text for additional jokes (or as the author calls them "Secret Words") in this [[http://www.whompcomic.com/2010/12/17/more-bang-for-your-bark/ comic]].Prior to this the text only displayed the comics title. The text can also be found by clicking the "Secret Words" button at the bottom of the comic.
* ''Webcomic/ASofterWorld'' allows you to either view alt text in the traditional way or by clicking on the comic, which causes a window to appear displaying the text. If you view it the traditional way, it may be entertaining for the easily-entertained to find a spot to hover which will cause the alt text to appear in a logical and aesthetically pleasing location respective of the actual comic.
* ''Webcomic/NotEnoughRings'' also uses alt text for additional jokes.
* ''Webcomic/EverydayHeroes'' includes additional punchlines (or commentary, for serious episodes).
* ''Webcomic/LucidSpring'' uses it, mostly to poke fun at the [[ButtMonkey characters]] and the [[SelfDeprecation writing]].
* ''Webcomic/{{Unity}}'' is generally a serious, sci-fi/drama comic -- except in the alt text.
* ''Webcomic/AliceAndTheNightmare'' uses alt text for additional worldbuilding and introducing characters whose names aren't given in text.
* ''Webcomic/CyanideAndHappiness'' doesn't use alt text, but the filenames under which each comic's graphical image is stored often contain hidden messages of their own. For instance, if you look at the [[http://explosm.net/comics/955/ comic for 13-July-2007]], and right-click over the comic itself and choose "properties" or "save as", you'll see it has the filename assassinations-are-less-controversial-then-low-income-families.png.
* ''Webcomic/WeAreTheWyrecats'' uses alt-texts mainly as a means for the author to provide additional commentary or make dry quips.
* On the website for ''WebVideo/AtopTheFourthWall'', alt text appears when you position the cursor over the logo. This includes some running gags ("[[ComicBook/SupermanAtEarthsEnd I AM A MAN! (punch)]]"), call-backs to his reviews ("[[ComicBook/TheNewGuardians Snowflame feels no pain]]"), and even some SelfDeprecation ("My claim to fame: being punched by WebVideo/TheAngryVideoGameNerd once").
* ''Webcomic/AGirlAndHerFed'' began using these for extra jokes and occasional commentary roughly around when ArtEvolution started to hit the comic.
* ''Webcomic/TheRedac'' uses it on many pages, mostly for snarky comments or stray thoughts.
* ''Webcomic/BeyondBloom'' Has them on most pages. Often silly quips, commentary, or extra information.
