Listed below are some helpful coding resources for web design, with respect to HTML and CSS.
Created in 1998, W3Schools is a free coding resource that has tutorials and information about HTML5 elements, tags, formatting rules, etc.; as well as other coding styles (such as CSS, JavaScript, Python, etc.). I first heard of this website because a friend of mine from high school recommended it to me, and I have come to judge it as a valuable and reliable source in its own right. Last viewed 03/31/2026.
MDN, developed by Mozilla in 2005, describes itself as an "open-source, collaborative project" whose Web Docs and guides are managed by both a corporate team and community volunteers/partners. They have articles and tutorials that cover information about HTML (and other coding languages), both for beginners who are learning the coding language from scratch and for experienced users who are confirming how specific elements work. I referred to MDN in a previous HTML course and have confidently recommended it to others as well. Last viewed 03/31/2026.
While both of the previous resources covered HTML, CSS, and other coding languages, CSS-Tricks - initially launched by Chris Coyier as a web design blog in 2007 - has grown into a major development resource over the last 2 decades. Some of the articles that relate to CSS cover box sizing, centering content, and working with flexbox and grids. It also has some tips about accessibility and images. Last viewed 03/31/2026.
Web.dev was launched by Google in November 2018, and its goal was to provide guidance, best practices, and tools to help web developers improve web performance, security, and accessibility. It has several types of coding and web development resources on it, but the source I've linked to specifically refers a self-learning CSS course. The articles grouped in this course discuss topics like nesting, specificity, inheritance, spacing, borders, and other design elements. Last viewed 03/31/2026.
Developed in 2015 by Dixon & Moe, HTML Color Codes is a free design tool that lists common colors in hex, RGB, and HSL codes. It also provides a color library of popular shades and colors, lists 140 named CSS colors, and has a color picker tool for different shades, tints, and tones (be they self-selected from extracted from an image). This will make browsing colors easier while I code HTML. Last viewed 03/31/2026.
UX Movement was founded by Anthony Tseng in 2010, serving as a digital publication that teachers readers how to improve the user experience of websites, apps, and interfaces. Although it doesn't directly correlate with HTML, it is a thought-provoking resource that can get HTML coders thinking about their websites and how usability should go hand-in-hand with design, not separate.

This website speaks for itself. Creative Commons is an international nonprofit organization whose goal is to "give every person and organization in the world a free, simple, and standardized way to grant copyright permissions for creative and academic works; ensure proper attribution; and enable others to copy, distribute, and make use of those works." Thanks to their efforts, copyright-free images on this website can be utilized on non-commercial sites. They are quite reputable. Last viewed 03/31/2026.
Unsplash was founded in 2013 as a "humble Tumblr blog" and has grown into a leading copyright-free visual community. Their images can be utilized for both commercial and non-commercial purposes, so long as their images are not used to built a direct competitor to Unsplash. There is a subscription available to those who want to crop, resize, and remove backgrounds on the photos they provide; but the image services themselves are generally free. Last viewed 03/31/2026.
