Though writing or working with code might not be your primary job as a UX designer (or in your job description at all) it’s a skill that will take your work far. Having a basic understanding of the languages developers and engineers use will not only give you better perspective on how your designs come to life and help you communicate across teams, but it will also allow you to become nimbler in your work processes. (Fair warning: Your developer friends may miss your occasional Slacks asks for minor changes.)

While there are many languages used in building a website, CSS is just one of the more commonly-used style sheet languages you may want to become better acquainted with. You’ve possibly already worked with it while running audits with developers, making small, stylistic tweaks to built-out designs, or building your own interactive prototypes outside of InVision Studio.

To make these tasks (and more) easier, it helps to have a great CSS editor in your toolbox. Whether you’re in the market for a new one (or want help choosing your first), we’ve put together a list 10 of the best on the market.

… but before we dive into them, let’s get on the same page:

What is CSS?

Just a quick refresher: CSS stands for “Cascading Style Sheets.” It’s a style sheet language that helps you control the look of several pages (like the background color or graphic) on a website all at once using just a single file. Instead of having to go into each individual page’s HTML code and manually make changes, .css files can make broad changes across all pages on a site.

Why do designers need CSS editors?

We touched on it above, but designers need CSS editors to easily access and make any changes to a .css file when collaborating with engineers or developers, or building out their own designs. Not only does having a CSS editor allow you to make these changes, but they present the code in a simple way that minimizes the chance of introducing errors into the file.

Okay—now back to your options for CSS editors:
