css table border settings

CSS tables are a very important part of web design. Setting table borders can help us control page layout, increase aesthetics and readability. In this article, I will explain how to set table borders using CSS.

1. Use the border attribute

The border attribute of CSS can set the border of the table. There are two steps to using the border attribute. The first step is to determine the style of the border. CSS provides the following border styles:

1. solid: solid border
2. dotted: dotted border
3. dashed: dotted border
4. double: double border
5, groove: 3D groove border
6, ridge: 3D raised border
7, inset: 3D inward concave border
8, outset: 3D outward raised border

For example, we can use the following code to set a solid border:

table {
  border-style: solid;
}

The second step is to determine the color and width of the border. CSS provides the following properties:

1. border-color: border color
2. border-width: border width

For example, we can use the following code to set a blue solid border :

table {
  border-style: solid;
  border-color: blue;
  border-width: 1px;
}

We can use this attribute to control the border of the table to make it conform to our web design.

2. Use the border-collapse attribute

In the table, there will be a certain interval between the table cell borders by default, which often affects the aesthetics of the table. To solve this problem, we can use the CSS border-collapse property.

The border-collapse property is used to control whether the borders of adjacent cells in the table are merged. By default, the attribute value is separate, indicating that the borders of adjacent cells are separated. We can use the following code to set it to collapse, which means that the borders of adjacent cells are merged into one border:

table {
  border-collapse: collapse;
}

This attribute is used to exclude the spacing between cells in the table to make the table look neater and clarity.

3. Use the border-spacing property

The border-spacing property is used to control the spacing between cell borders. This property can be set using the following code:

table {
  border-spacing: 5px; 
}

The value of this property represents the spacing pixel value between cells. Using this value can make the table appear clearer and more beautiful on the page.

4. Use the style selector to control the table border

In addition to the properties introduced above, we can also use the CSS style selector to control the table border. For example, we can use the following code to set a solid border for each cell in the table:

table td {
  border-style: solid;
  border-width: 1px;
}

Using this method, we can more flexibly control the style of the table to make it conform to our web design.

Summary:

CSS tables are a very important part of web design. When setting the table border, we can use the border attribute, border-collapse attribute, border-spacing attribute and style selector to control the table border style. These properties and methods can help us control page layout and increase aesthetics and readability.
