Stylish is an interesting extension for Firefox, giving the user a convenient way to edit the appearance of both selected websites and the interface of the web browser itself. The extension allows you to easily and efficiently modify the appearance of any website. With its help, we can adjust the font size and font typeface, color scheme of individual elements of the website, but also redesign its entire appearance - hide content irrelevant to us and change the way it is displayed.

The way Stylish works is very simple and is based on forcing the browser to use a different than the default cascading style sheet (CSS) to display the page. In order to create your own styles, you need to be familiar with these CSS worksheets, which are commonly used to design web pages. Stylish gives you the ability to create multiple styles for a particular site and then display its content using one of them.

The process of creating a new style can be initiated from the extension icon located at the bottom of the browser. A simple but fully sufficient style editor for syntax highlighting is available to the user.
