How to edit blocks with predefined css classes in wordpress?

Question

Do it yourself

Greetings.
There is a small website with 5 different pages. There are many blocks with classes and their own styles on the old ones, each page with its own unique design.
For example, there is a block

<div class="title">Site title</div>
<div class="sub-title">Sub-title</div>

The classes have a font, font size, color, indentation, etc. and I would not like to let these classes and blocks be edited, but only the text itself.
Who has experience with WP, tell me how you solve this problem?

Answer 3

If the coolers do not start when turned on or jerk and turn off - there is an assumption that the protection in the PSU is triggered - something is shorting to the case.
If the coolers start, remove everything from the case, including the memory, leave only the CPU :) If it starts beeping after starting, the fact that there is no memory is detected, this is already something. (if not, the mother most likely died)
If you remove the cooler from the processor and turn it on for a few seconds, then if the processor warms up so that the finger feels - it is alive. If cold - a corpse.

Answer 4

WordPress has its own customizer. What for to you third-party ACF? It's like shooting sparrows from a cannon. Use the VI customizer and its api
