CSS is used to modify web page styles. However, if you want the styles modified by CSS to work, you must introduce a CSS style sheet into the html file. There are three common ways to introduce style sheets, namely inline, embedded, and external links. The following article will give you a detailed introduction to embedded.
CSS Embedded
Inline is to write the CSS code in the 93f0f5c25f18dab9d176bd4f6de5d30e header tag of the HTML document, and use c9ccee2e6ea535a969eb3f532ad9fe89 Tag definition, its basic syntax format is as follows:
<head>
<style type="text/css">
选择器{属性1:属性值1;属性2:属性值2;属性3:属性值3;}
</style>
</head>In this syntax, the c9ccee2e6ea535a969eb3f532ad9fe89 tag is generally located after the b2386ffb911b14667cb8f0f91ea547a7 tag in the 93f0f5c25f18dab9d176bd4f6de5d30e tag, or it can be placed at the end of the HTML document Anywhere. However, since the browser parses the code from top to bottom, placing the CSS code in the header facilitates downloading and parsing in advance to avoid the embarrassment caused by no style modification after the web page content is downloaded.
