Design of xkcd.com

The four segments on xkcd.com

The design of xkcd.com includes four white segments, which are separated by a thin black border and a light blue-gray background color. All text on the page uses a small caps font, except for the word "xkcd" in the logo image. Here is a list of the changes that have been made:

The design has changed many times over the years, but mainly in the beginning. Prior to October 24, 2004, the website didn't mention the name "xkcd" and didn't include any comics. During that time, the site's message simply stated: "I don't use this page for much. It goes un-updated for a long time, and I don't really change the content, though I'm thinking of putting together a good links page. For now I just mostly use this to host pictures.". Before October 18, 2005, the website was redesigned to be used to host xkcd comics. Between July 6, 2006 and July 10, 2006, the design of the website changed dramatically to one very similar to the current one.

Links

The first segment is at the top left of the page, and it contains links to navigate around on xkcd.com and his social accounts. There have been multiple changes to the links over the course of the site's history, with the last one being made in 2023. It states:

Header

The second segment is the header, which contains the logo, the tagline, and the header text. The header is wider than the first segment but has the same height. The xkcd logo is positioned on the upper left corner and serves as a clickable link to the front page. The image used in the logo of xkcd is from the first panel of 77: Bored with the Internet, showing only the characters and the chair and the desk with a now old fashioned computer screen. The color of the text in the logo is a shade of grey/gray(spelling varies with location), with a hex value of #6e7b91, and an rgba value of (110,123,145,255).

Tagline

For more information, visit the main article.

Next to the logo is the tagline, a short text that appears regardless of which comic is being viewed. There have been eight taglines displayed over the course of the site's history, with the current one being added in 2006. It states:

A webcomic of romance, sarcasm, math, and language.

Header text

The header text is updated whenever Randall has news to share. After the novelty of the news ends, the page usually goes back to its default header text, which states:

xkcd updates every Monday, Wednesday, and Friday.

Comic

This section of the website is dedicated to displaying comics. Positioned above the comic is the title, presented in large and bold lettering. Just below the title, but above the primary comic image, there are five buttons. They follow a fairly standard layout: on the outer edges are the

|<

and

>|

arrows, which transport the user to the first or most recent comic accordingly. Adjacent to these are the

< Prev

and

Next >

buttons, allowing navigation between the comics immediately before and after the currently displayed one. In instances where the displayed comic is the first or the last, attempting to access the previous or next comic will simply result in the page being reloaded. At the center there is a

Random

button, which, when clicked, loads a comic at random. The same set of buttons is duplicated below the comic as well. While this redundancy isn't needed in most comics, it ensures that the buttons are conveniently accessible both before and after scrolling, especially for large comics.

Finally, beneath this second row of buttons, two links are provided. The first functions as a permalink, directly linking to the comic currently displayed on the page. In some cases, custom permalinks are used for various versions of the same comic, such as in some of the interactive comics like 1350: Lorenz and 1663: Garden. The structure of this link consists solely of the xkcd.com domain followed by the respective comic number. For instance, the link for comic 2000: xkcd Phone 2000 would appear as: "https://www.xkcd.com/2000/". The second link leads to the image URL suitable for hotlinking or embedding, in this case "https://imgs.xkcd.com/comics/xkcd_phone_2000.png". This link is stored within a comics-specific logical subdirectory of the server. The filenames of these images typically align with the comic titles, although exceptions arise, particularly in cases of title conflicts or when the visible comic is dynamically generated or a composite rendering.

Permanent link to this comic: https://xkcd.com/2000/

Image URL (for hotlinking/embedding): https://imgs.xkcd.com/comics/xkcd_phone_2000.png

Warning

For more information, visit the main article.

The warning on xkcd was originally added to the site in 2006, but it was removed in 2016. It stated:

Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors).

Footnote

For more information, visit the main article.

The footnote on xkcd is written in a very tiny font, which makes it very hard to read without zooming in. There have been two major footnotes displayed over the course of the site's history, with the current one being added in 2016. It states:
