I have just been asked to look at a website and see if there are any ways to improve its Page Load speed.
I have identified that there are a lot of duplicate CSS Entries, across a lot of separate CSS Files. Is there a way I could copy all of the CSS into a single Stylesheet and then enter it into some kind of software etc, which would output all of the Elements such as Buttons, Menu Items and the such? As such, allowing me to use the such an Output as some kind of Checklist in the recreation of a more efficient CSS File?
As an extra benefit, it would be ideal if such software would be able to identify any duplicate entries too. The collective CSS lines are over 150k, so it would take a while to go through this manually.
Unfortunately, the website owner never created a Pattern Library.
