HTML and CSS #

HTML is a language used to describe the elements composing a graphical interface, with which CSS is associated, allowing the appearance of these elements to be defined.

JSBin allows you to view an interface programmed in HTML/CSS on the fly.

There is a wealth of documentation on HTML and CSS, both on the web and elsewhere (https://developer.mozilla.org/docs/Learn/HTML and https://developer.mozilla.org/docs/Learn/CSS, for example). Note that many of these documentations will mention JavaScript, a language associated with web technologies of which HTML and CSS are a part. However, using HTML and CSS in Zelibinium does not require any knowledge of JavaScript.
