This case is how to use CSS to hide the text content of the image background. We first use backgroundThe background is to set the image as the background display; then use text-indent The indent is to hide the a link content and the link tag is to set the anchor text link to the text. Below are examples.
Example case description

Extended reading: html img picture
1. CSS code:
h1#logo{
float:left;width:165px;height:60px;
background:url(http://www.php.cn) no-repeat 0 0}
h1#logo a{display:block;width:100%;height:100%;text-indent:-9999px}
/* css comment: display:block is the A within the #logo Labels are displayed in blocks and displayed with 100% height and 100% width
text-indent This attribute is the CSS indent style. We set it to a negative value of 9999px, which hides the text in the a label
In this way, the h1 tag background image is displayed, the text is hidden and the A anchor text is realizedHyperlink
*/
2. HTML Code:
<h1 id="logo"> <a href="http://www.php.cn/" title="PHP中文网"> </a> </h1>
Case effect
Display the results in the browser. You can follow the example code to think about and complete the DIV+CSS practice, and test it in the browser.
Important explanation: Originally, text content was set in the h1 tag in HTML, but setting the "text-indent:-9999px" style essentially moves the text to the left by a distance of 9999px, which is naturally displayed on a normal resolution display. The 9999px edge content cannot be seen. Naturally, this CSS technique is used to hide the text and at the same time, the background image is displayed normally.
Summary
We use the image as the CSS background, put text on it, and hide the text. This is more practical for SEO. But in actual operation, pay attention to the size, height and width of the image. When setting the object DIV box, pay attention to the appropriate height and width, and use CSS background style, text-indent, css display and other style words to achieve it. You can learn it through practice based on cases and multiple examples. If you don’t want to use the A anchor text to hide the text on the image, you can replace the a tag with a span tag, div tag, or em tag, which will have the same effect.
