This newbie has a simple mechanics question. What do I do, after I have modified the style.css or html code of my child theme, to save the results and update my site?
Ex: I want to play with font weight in the text of my posts.
I go first to my dashboard, then I launch Firebug. Next I bring up a post to edit; I select a paragraph, go the Firefox tools, select Firebug, and click "Inspect this element".
In the html window (bottom left) I see my text hilited in blue.
In the css window (bottom right) I think I see css coding.
In the beginning, before I messed with it, "font weight = inherited
What's going on and where do I go from here?
Many thanks for your help!
