Stylesheet class...quick list for what's what on the page

[AllofUs]

I saw a "sticky" for a quick way to determine what the css class/id is for the format on your pages. However, it is for Firefox. I do not use Firefox. I have Dreamweaver.

For instance, I want to change the color of sidebars, backgrounds, certain texts or fonts, etc. Is there a list to know when I see the following class below, I'll know where it is located on the webpage. Meaning, the list will be my "guide/reference check" as I want to modify for a specific part of the page.

a:visited {
color: #3300FF;
text-decoration: none;
}

I hope this makes sense.
