Today I will explain to you how to use CSS to operate various styles of DIV dotted borders. Dotted underlines and dotted lists can be used to draw inferences, so that you will no longer struggle with solid and dotted lines! First, let's take a look at a DIV with dotted borders on all four sides.

One and four sides are dotted borders

border:1px dashed #000; black dotted border

Example:

CSS代码： .div{border:1px dashed #000; height:50px;width:350px}
Html代码： <div class="divcss5">我的四边为黑色虚线边框</div>

2. Dotted line on the left:

CSS code: .div{border-left:1px dashed #000; height:50px;width:350px }

Here I set a black dotted border on the left side

3. Dotted line on the right:

CSS code: .div2{border-right:1px dashed #000; height:50px;width:350px}

Html code:

Here I set the right side to be a black dotted border

4. The top edge (upper edge) is a dotted line:

CSS code: .div3{border-top:1px dashed #000; height:50px;width:350px}

Html code:

My The top edge is a black dotted border

Here is the top edge (upper edge) and one side is a black dotted border

5. The bottom edge (lower edge) is a dotted line:

CSS code: .div4{border-bottom:1px dashed #000; height:50px;width:350px}

6. Either side is not dotted,Others Three sides are dotted lines

Add the right border that is not dotted but no edge, and the other three sides are black dotted borders

CSS code: .div5{border:1px dashed #000; border-right:0; height:50px;width:350px}

Html code:

Here, the object is first set with a black 1px dotted border on all four sides, and then sets one side to 0, which is equivalent to setting a 3-sided border dotted line. Attributes, but pay attention to the order before and after setting the border attributes here.
