CSS is an indispensable part of front-end development. In addition to controlling the layout and style of web pages, you can also change fonts through CSS. Font selection and size are very important to the user experience and visual impact of your website. In this article, we will discuss how CSS changes fonts.
Introduction of CSS fonts
In CSS, you can load custom fonts into the website through the @font-face rule. To use a custom font, you need to download the font file. Common font file formats include TTF, OTF, WOFF, EOT, etc.
It is generally recommended to use font files in TTF or WOFF format, because these two formats are supported by most browsers and devices. For example, to load the font file myfont.ttf into a website, you can use the following code:
@font-face { font-family: 'myfont'; src: url('./fonts/myfont.ttf') format('truetype'); font-weight: normal; font-style: normal; }

p { font-size: 16px; }
CSS Font Styles
