Remove borders from html table

HTML tables remove borders

In HTML web pages, tables are a common way to display structured data. In addition to cell color, content alignment, etc., the most common appearance of the table is the border. By default, HTML tables display borders to better differentiate table contents. However, in some cases, we need to remove the borders of the table to better integrate into the overall design of the page. This article will introduce how to use CSS to remove borders from HTML tables.

Method 1: Use the border attribute

The most common method is to use the CSS border attribute. The border property is used to set the border style, color and width. We can set the width to 0 and the style and color to none to achieve the effect of removing the border. As shown below:

table {
  border-collapse: collapse; /* 合并边框，避免两条边框相交时出现两倍线的现象 */
}

td, th {
  border: none; /* 去掉单元格边框 */
}

Among them, the border-collapse attribute is used to merge the borders of adjacent cells to avoid the phenomenon of double lines when two borders intersect.

The advantage of this method is that it is simple and easy to use, and the code is short and concise. At the same time, it is also suitable for removing the borders of certain cells. Just add border: none; to the corresponding td or th element.

Method 2: Use CSS selector

Using CSS selector can more accurately select the cells that need to have their borders removed, achieving a more flexible effect. Taking the border of the first row of cells as an example, the code is as follows:

table {
  border-collapse: collapse;
}

tr:first-child td, tr:first-child th {
  border-top: none;
}

Among them, tr:first-child is used to select the first row, td and th are used to select ordinary cells and header cells. . The border-top property is used to remove the top border.

After removing all the borders of the cells in the first row, the table will become more concise and clear. At the same time, in some cases, we can also choose to remove only the left or right border, or remove all internal lines, which can be achieved through CSS selectors.

It should be noted that the code for using CSS selectors to remove borders is relatively cumbersome and requires a certain understanding of the table structure. Therefore, in simple web design, we use the first method more, while in complex web design, we are more inclined to use the second method.

Summary

Removing the borders of HTML tables is a common technique. We can use the CSS border attribute or CSS selector to achieve this. Both methods have their own advantages and limitations and need to be chosen according to the specific situation. In actual web design, we can make choices based on the structure and needs of the table to make the table more beautiful, neat and easy to maintain.
