Doesn’t seem to have any effect.

Primarily interested in reducing the size of the title at the top of the lesson page: Lesson 3: Aeronautical Sectional Charts

Please try this, so sorry i miss the # before code
#popup-sidebar .section-item-link .item-name {
font-size: 15px !important;
}

Beautiful! Thank you! And no worries! That worked beautifully!

Can I trouble you for some CSS that will allow me control over the titles too?

The font size depends on the font size of your theme, we don’t set a fixed value for the font. You can change the font of your site and recheck.

Thanks Brian,

I’m using Total WordPress theme by WPExplorer, so the font size is not dependant/affected upon the theme unfortunately. Some things change like the type of Google font, but font size isn’t affected.

Thankfully, my theme author educated me on how to use the Developer Tools within Chrome to create my own custom CSS. So I was able to change the font size for the side menu, font size for lesson titles, side menu title font size, profiles and course progress font size and layout, more.

I know my changes can possibly become negatively affected with future LearnPress updates, but being able to make these adjusts was desperately needed to keep my entire site more fluid.

If anyone is interested in some free CSS for LearnPress, visit my profile and scroll to the bottom. Each piece of code is labeled as to what it affects. Disclaimer: I’m not a coder… just a very right-brained learner.

Thanks again for all your help Brian. LearnPress is great!
