A brief analysis of how to change font style using CSS

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;
}

This code defines a font named myfont, using the font file myfont.ttf as the font source path, And specify the font weight and style as normal. After that, you can use the font in web pages.

CSS font family

There are five general font families (Generic font family) in CSS, they are:

• Serif (serif): in the font The strokes have decorative lines at the end and are often used in printed materials.
• Sans-serif: There are no decorative lines at the end of the strokes. It is usually used for digital displays and screen displays.
• Monospace (monospace font): Each character has the same width, often used in code editors and terminals.
• Cursive: A font that looks like handwriting.
• Fantasy (artistic font): artistic font, such as cursive script, rainbow characters, etc.

If the font family is specified but the font is not introduced, the browser will look for the corresponding font in the operating system. If the font is not available in the operating system, an alternative font is used.

CSS Font Size

CSS font size can be specified using length units or percentages or keywords. Among them, the length units include px, em, rem, pt, etc.; the percentage is calculated relative to the font size of the parent element; commonly used keywords include small, medium, large, etc.

For example, to set the font size in the p element to 16 pixels, you would use the following code:

p {
  font-size: 16px;
}

p {
  font-style: italic;
}
