What is the issue.
That nothing is displayed or nothing change if the option “Disable the build-in CSS for this widget” is checked?
I installed the Evolve Theme and as you mentioned there is not a big change between to have this option checked or not.
So it depends on the Theme CSS, what is done for widgets. This is what we’ll expect 😉
We recommend Child Themes to write your own CSS code and change some styles.
I apologize for not being more clear. If you take a look at this page (https://thelemicknights.dream.press/), perhaps you will see what I am failing to put in words 🙂 Specifically, look at the font for the Title of the Widget (OTK news).
Have you checked the thumbnails option?
Here is our documentation: http://tiptoppress.com/category-posts-widget/documentation-4-7/
I found the issue. The theme changed the size of the widget title because I had made the title a link. D’oh.
Thank you so much for your quick responses. I will likely be purchasing the pro version soon. Just have to get permission from the folks who asked me to do this for them. 🙂
