Claude Code has some powerful skills for working with web applications. One particularly useful one is the front-end designer skill, which gives Claude the ability to actually see what your web pages look like.

This skill uses Puppeteer under the hood to take screenshots of your application. So instead of just working with HTML and CSS code blindly, Claude can actually load up your page, take a screenshot, and see what it looks like visually.

This is incredibly helpful for debugging layout issues, checking responsive design, or making sure your styling changes actually look the way you intended. Claude can tell you things like "the button is overlapping the text" or "the navbar isn't aligned properly" because it can actually see the rendered page.

To use it, you just need to have the front-end designer skill installed from the plugin marketplace. Then you can ask Claude to take a screenshot of a particular URL or test a specific component visually. It's like having a pair of eyes on your front-end work.
