Presence of spaces matters in CSS selectors, #main .ace_content
means “an element with class
containing ace_content
inside an element with id
of main
”. #main.ace_content
means “an element with class
containing ace_content
and id
of main
”. Generally, copying the selector as-is from the Elements tab is a good bet; you can try
document.querySelectorAll(`#main .ace_content`)
in Console to see what elements match your selector. (also see Finding what to style)
I don’t think I have it in me to do more YouTube tutorials at the moment - the fact that you can’t edit them after upload has it that either the video is going to be longer than it should be, or that a few-minute video takes several hours to plan, [re-]record, and write subtitles for. I’d like to experiment with more ways to handle step-by-step demonstrations in text tutorials though.
