I’ve renamed the section headers on my Front Page. However, I would like to resize them and make them bolder. Is there a CSS code that will change that without overriding my current customized CSS? I’ve tried using the other recommendation in other topics, but doesn’t work or doesn’t stay when I make other customizations. Any clues?
It looks like h3 on your site has a default font weight of 100.
You could use the CSS h3 {font-weight:500!important} to increase the boldness of your h3 tags across your whole site.
Or you could use .front-page .section-header h3{font-weight:500!important} to only change the front page section headers. I think font-weight:bold; is a thing also if you don’t want to do it using number values.
