Finding the Theme

Locating a theme for DevTools is straightforward. A quick Google search yields plenty of options. Some themes might change just the syntax highlighting colors, while others might revamp specific panels only.

Yet, some exceptional themes comprehensively transform the entire DevTools interface, including fancy animations. Here are a few of my top picks.

Installing the Theme

Installing these themes is a breeze, as they are primarily CSS-based. Start by downloading the CSS file from a chosen source, such as the Monokai Theme.

For macOS users, navigate to Finder, press Command + Shift + G, and enter: ~/Library/Application Support/Google/Chrome/Default/User StyleSheets/.

Guide to locating directory in macOS for DevTools theme installation

In this directory, an empty CSS file named Custom.css awaits. Open it with your code editor and insert the styles from your downloaded theme.

For Windows and Ubuntu users, locate the Custom.css file here:

Windows 7 and 8: \AppData\Local\Google\Chrome\User Data\Default\User StyleSheets\Custom.css

Ubuntu: ~/.config/google-chrome/Default/User StyleSheets

Changes take effect immediately, no need to restart Chrome. Enjoy your newly styled DevTools!
