When a hyperlink becomes active or receives focus, a dotted line appears around the link to distinguish it from other links. This is the default behavior of hyperlinks. It's basically a dashed outline that doesn't affect surrounding elements like a border. If we want to remove the css dotted line style, we can use the CSS property "outline:none;" to achieve this.
Let’s take a simple example to introduce how to remove the css dotted line style.
The code example is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>使用CSS删除虚线轮廓</title>
<style type="text/css">
a, a:active, a:focus{
outline: none; /* *适用于Firefox，Chrome，IE8及以上版本* */
}
</style>
</head>
<body>
<div class="menu">
<a href="#">Home</a> | <a href="#">About Us</a> | <a href="#">Contact</a>
</div>
</body>
</html>outline (outline) is a line drawn around the element, located outside the edge of the border, which can highlight the element. The outline attribute sets the outline around the element.
Note: Always declare the outline-style attribute before the outline-color attribute. The color of an element's outline can only be changed after it has obtained its outline.
Note: Contour lines do not occupy space and are not necessarily rectangular.
The default value is none.

How much specificity do @rules have, like @keyframes and @media?Apr 18, 2025 am 11:34 AMI got this question the other day. My first thought is: weird question! Specificity is about selectors, and at-rules are not selectors, so... irrelevant?

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
