Is there a way in Chrome web dev tools, to alter the site (CSS for example) and measure / compare the loading performance before and after the edits ?
If I change the CSS, as soon as I reload the page (in the Network tab) it reloads the original CSS - obviously.
I would need to somehow make the changes permanent, or save the altered state in order to compare it to the original.
