Editor to share with you how the css statement grouping, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

We group either the determiner or the declaration in general.

If you want all H2 elements to have a blood background and use a 28-pixel high Verdana font to represent blue text, perhaps write the following style:

H2 {font: 28px Verdana;} H2 {color: blue;} H2 {bac kilogram round: red;}

However, the humiliation of the above practice is actually not high. It is quite convenient when we build such a list for an element with multiple styles. Instead, we might group fame together:

H2 {font: 28px Verdana; color: white; bac kg round: black;}

This is no different from the achievement of the three-line stylesheet on the back.

Be careful, to group statements, it is not necessary to apply semicolons at the end of each voice, which is very necessary. The reader ignores blank characters in the stylesheet. Only by adding a semicolon, that is, Dazhong unscrupulously adopts the following pattern to establish the style:

H2 {font: 28px Verdana; color: blue; background: red;} above is all the content of the article "how css declares the grouping". Thank you for reading!
