How to Use Browser Developer Tools To Debug and Optimize Your Web Pages

If you’ve been using a modern browser for any period of time, you’ve probably come across developer tools to improve your web browsing experience. These tools are built into the bowels of every modern web browser, and they can be used to optimize your website pages, debug problems, and even launch third-party websites from within the browser itself.

What Are Browser Developer Tools?
The developer tools section of your web browser provides access to a large number of features to help you create better web pages. These features are generally categorized under the following headings: Network Connections – This section provides access to metrics and graphs about your internet connection, as well as tools to optimize your download speed. Memory – This section shows you which parts of your website are spending the most memory, as well as information about any resources that may be using up your computer’s memory. GPU – This section shows off just how powerful your computer’s graphics card is by showing you graphs and metrics about your video, image, and website rendering performance. JavaScript – This is where the magic happens. This is where you learn how your website is using the computer’s resources, and which parts need more love. Tab Stacking – This is another common issue with new web designers, where a section of your web page is open on multiple tabs. This problem can be resolved by closing a few of the tabs, but it’s easy to forget.
