What Are the Best Practices to Ensure a Well-Running Website?

To assess performance, you’ll want to leverage your browser's developer tools. The Network tab is great for understanding loading times, while the Performance tab can help identify any bottlenecks. If you're relying on a framework, those often come with their own set of developer tools to simplify this. For accessibility, automated tools like Lighthouse (check it out [here](https://developer.chrome.com/docs/lighthouse)) can point out common issues, but you should also read up on HTML elements to ensure they're screen-reader friendly. Keeping up with the latest on SEO changes is crucial too, as that field evolves constantly!

Don't forget about media queries! A common mistake is making them too complex. Start with min-width media queries—the rule of thumb is to design for mobile first, then scale up. For example, set a base style for mobile, then add queries for tablet and desktop sizes. Another tip is to utilize REM and EM units for font sizing to reduce the need for many media queries. Using ‘clamp()’ can also help with responsive font sizes!
