I hope you can get something after reading this article. Let's take a look at this "how to express the class selector of CSS" article.

In CSS, the class resolver is represented by a period:

.center {text-align: center}

In the above example, all HTML elements that own the center class are centered.

In unfamiliar HTML code, both H2 and p elements have center classes. This means that both will listen to the delineation in the ".center" selector.

This heading will be center-alignedThis paragraph will also be center-aligned.

Hold steady: the first character of the class name cannot apply a number! It has no choice but to sense in Mozilla or Firefox.

Unlike id, class can also be used as a derived resolver:

.fancy td {color: # f60; background: # 666;}

In the above example, the table units inside the larger element named fancy are orange ink with a gray background. (a larger element named fancy may be a table with a div.)
