Now that we have an understanding of how to create HTML, it's time to get more indepth with the CSS rules to style HTML. Each HTML code has properties that are pair with a CSS, and the CSS can relate to different visual aspects of onscreen positions, width of its broder, the sizing, colors, fonts, and text (just as a few examples). Each CSS has associated styles, and when applied, they are called the CSS rule.
Classes in CSS are used to identity the number of elements that are used as a shared set of characteristics. Let's say you have a list of dogs, some are brown and some are black, and in this list you would want to use the classes tool to identity their two seperate groups of their colr markup. The CSS rule for this would be to use "a", which has an ancestory connect with the class brown, and then the second rule elects any other "a" element which as the remaining ancestor of "black".
RGB and HSL allows you to specify a alpha channel value and set that specific opacity of the color you choose for your website element. In these formats, "A" is tyhe value to be set between 1 and 0 (the opaque and transparent). When determining your color for your website element you can specify a color by name, or, you can enter the keyword to use the color's offical term.""
