Convenient tools for website redesign?

Question

Design

Hello!
There is a site on wordpress, it works fine, but the problem is in the design, in the self-written template ...
It needs to be reworked and the question arose, what tools can be used to quickly and conveniently correct it?

Answer 1

The question is not very clear: what exactly to change?
If specifically the color, size, font, etc. - then either edit the theme files, or in some themes some simple changes are made to the admin panel in the settings.
