I've been lucky enough to feature in the latest edition of Web Designer Magazine with a tutorial titled "Website theming with CSS variables and Web Storage API".
In the tutorial, I explore a practical application of CSS custom properties (commonly known as CSS variables) and how they can be used to implement website theming into a mock web app called NoteApp. Web Storage API is then introduced as a means of maintaining the theme across multiple browser sessions.
It's a beginner level tutorial perfect for any developer looking to learn more about a real-world usage of CSS variables or Web Storage API.
In the UK, Web Designer Magazine is usually available in places like WHSmiths or any other half-decent newsagents. You can also order it online.
Have any follow-up questions about the tutorial, or just want to clarify any of the steps? Feel free to post in the comments below or shoot me over an email.
Update - The full tutorial is now available to read on CreativeBloq. Check it out.
