A website theme is a custom web design layout that allows the user to change many features such as brightness and contrast. The different areas of website themes include web graphic design; interface design; authoring, including standardised code and proprietary software; user experience design; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. Website theme designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines.


In 2014, while working as a web developer at Roblox, WebGL3D created Roblox+, an extension that allowed users to receive Catalog notifications. Among the features added was the return of the OBC theme, created in 2010 for OBC users as an incentive to get more users to buy. The theme had a dark color to it (compared to the blue and white theme), and was applied to all site websites.

This saw popularity in Google Chrome extensions built for Roblox, and many users started making theme changers, which would allow you to change your Roblox look to be any image you choose.

When Google Chrome extensions fell out of popularity, many users switched to Stylish to change the look of the site. Stylish allowed for Firefox users to change their look, instead of being limited to Google Chrome. Some of the most popular styles on the site include a dark theme for Roblox, a polygon look, a replacement for the logo that makes the logo look like a Cheez-it (a popular joke in the community), and an anime style.

Tools and techniques

Users on Stylish use a code editor and Inspect Element to copy the layout of the page. Once the HTML is applied, users can then make changes to the HTML, such as changing the font of a site, and upload it to the site.
