Chrome Development Tools tips
There are many unknown and hidden tricks of Chrome Dev Tools and we will be looking into the most useful ones. To open the developer tools in Chrome, press F12 on your keyboard and try the following tricks.
1. Find and Open any file
When we are doing web development, we deal with many HTML, CSS, JS, and other files. When we want to debug anything, we open Chrome Dev tools. You can quickly search and find the particular file to make your job easier. Just press Ctrl + P and start typing the file name. This helps you to find the particular file from the list of files.
2. Search within the source file
In the previous trick, we learned how to search for a particular file. You can even search for a particular string in all the loaded files. Press Ctrl + Shift + F to search for a string in files. It also supports regular expressions.
3. Go to a particular line

We can edit source files and make some changes in CSS, JavaScript, and other files in Chrome Dev tools. To add these changes to the local files, then there is no need to copy-paste the changes from the workspace to files on disk. Chrome Dev tools allow you to match files and update the local file with the changes you have done in the dev tools. To get this done right click on the source file on the left side on the Sources tab and select Add Folder to workspace. I hope this helps.
