When writing PHP code, sometimes you need to display some horizontal lines as separators on the page, but by default, a horizontal line will be automatically displayed below these horizontal lines. This makes the page look a bit ugly, so many developers want to know how to disable the underline. This article will introduce how to cancel the horizontal line below.
In PHP, the following syntax is usually used to display a dividing line:
<hr>
This syntax means to insert a horizontal line at the current position. If you use the default style, a horizontal line will appear below the horizontal line. If you do not want this horizontal line to appear, you can cancel its display in the following two ways.
1. Use style sheets
In HTML, you can use style sheets to add styles to elements. We can add styles to the hr element to control whether the horizontal line below it is displayed. By adding the following CSS style:
hr { border: none; }
This indicates that we do not want to use the default border style, thereby canceling the horizontal line below the horizontal line.
In the PHP file, you can add the style through the following code:
<style> hr { border: none; } </style>
This way you can control the hr element style and cancel the display of the horizontal line below.
2. Use div tags for packaging
You can also use div tags for packaging outside the hr element. Place the hr element in a div and use styles to control the bottom margin of the div to hide the horizontal line below the hr element. The specific implementation code is as follows:
<hr>
Here, the bottom margin of the div is set to -2px, which is equivalent to moving upward by 2 pixels, thus hiding the horizontal line under the hr element.
Summary
To cancel the horizontal line under the hr element in PHP, you can use a style sheet or div tag for packaging. Among them, the method of using style sheets is simpler and more direct and suitable for most situations; using div tags for packaging requires additional processing in HTML and is suitable for some specific situations. Which method to choose is mainly determined based on actual needs. I hope this article can help you solve the problem of canceling the display of horizontal lines below horizontal lines in PHP.
