How to define multiple styles in CSS

Next, please follow the editor to study!

Or define multiple formats for a border, such as:

P.aside {border-style: solid dotted dashed double;}

The following provision defines four border techniques for a paragraph named aside: the top border of the solid line, the left border of the dotted line, the lower border of the dotted line, and a double left border.

We also see that the values here take the measures of top-right-bottom-left, and we have also seen this in the case of using multiple values to configure unsuitable inner margins.

Defining unilateral techniques

If you want to set up a border pattern for one of the edges of the element box, instead of configuring all four border patterns, you can use the following one-sided border pattern attributes:

Border-top-style

Border-right-style

Border-bottom-style

Border-left-style

So these two methods are equivalent:

P {border-style: solid solid solid none;} p {border-style: solid; border-left-style: none;}

Hope: if you want to apply the second door path, you must put the unilateral attribute after the abbreviated attribute. Because if you put a unilateral attribute before border-style, the value of the abbreviated attribute will mask the unilateral value none.
