Effect picture:
The above example is to set the upper, lower, left and right borders at the same time , you can also set the border on one side separately: border-top-style (top border), border-bottom-style (bottom border), border-left-style (left border), border-right-style (right border).
2.border-width attribute
Set the border width. There are two ways to specify the width of the border: you can specify the length value, such as 2px or 0.1em (units are px, pt, cm, em etc.), or use one of the 3 keywords: thick, medium (default), and thin.

Note: The "border-width" attribute has no effect if used alone. You must first set the border using the "border-style" attribute.
3.border-color property
Set the color of the border. Colors that can be set:
name - the name of the specified color, such as "red"
RGB - Specify RGB value, such as "rgb(255,0,0)"
Hex - Specify a hexadecimal value, such as "#ff0000"

<body>
<div class="demo">

Rendering:
Note: If the "border-color" attribute is used alone Doesn't work. You need to set the border first using the "border-style" property.
4. Border - abbreviation attribute
The above are to set different attributes of the border separately, or you can set different attributes of the border at the same time, for example:
border:5px solid red;

2: Border rounded corners
border-radius: Set rounded corners on all four sides of the border at the same time
Border-top-left-radius: Set the upper left corner of the border to be rounded
Border-top-right-radius: Set the upper right corner of the border to be rounded
border-bottom-left-radlius: Set the lower left corner of the border to be rounded
border-bottom-right-radius: Set the rounded corner of the lower right corner of the border
As the name suggests, you can add a rounded corner effect to the border after setting the basic properties of the border
