I want to edit a web page in Google Chrome, the problem is that there are no "Sources" for that web page, i.e. it contains only one html page. Tell me if I am making a mistake, I know it can be from the Sources tab but there are no CSS or JS files, its just a simple html page.
Thank You
On Chrome press F12, Select Elements tab, navigate to the element you want to edit. Right click > Edit as HTML and at the right, in the styles, add a new rule to apply on the page.
