How to change font in HTML

HTML is a markup language used to create web pages. Through HTML, we can describe the content, structure and style of a web page. Among them, style refers to the font, color, size, background and other visual effects in the web page. In this article, we will mainly discuss how to change fonts in HTML.

The default font in HTML is the font that comes with the browser. These fonts may differ across browsers and operating systems. In order to ensure that web pages have consistent visual effects on various devices, we can use common web fonts.

Web commonly used fonts refer to fonts that can be displayed in various operating systems and browsers. Among the more common ones are Song font, Kai font, Helvetica, Microsoft Yahei, Arial, Tahoma, Helvetica, etc. When using common web fonts in HTML, we need to define a font family in the CSS style sheet. A font family refers to a collection of multiple fonts. You can specify a set of alternative fonts. When the previous font is unavailable, the browser will render the alternative fonts in sequence according to the specified order.

For example, we can define a font family to use the Microsoft Yahei font. The code is as follows:

body {
  font-family: "微软雅黑", Arial, sans-serif;
}

In this example, we first specify the Microsoft Yahei font. If the font is not available, then use the Arial font. If even the Arial font is not available, finally use the sans-serif font. A sans-serif font is a regular font without serifs, often used in web design.

In addition to specifying the font family, you can also use various font properties to change the font. Commonly used font attributes include font size, font color, font thickness, font style, etc.

Font size refers to the relative size of the font, usually in "em" units. For example, we can set the font size to 16 pixels. The code is as follows:

p {
  font-size: 16px;
}

The font color can be set using the CSS "color" property. Colors can be represented by predefined color names or hexadecimal color values. For example, we can use red font. The code is as follows:

h1 {
  color: #FF0000;
}

The font thickness can be set using the "font-weight" attribute. Font weights usually include "normal", "bold", "bolder" and "lighter". For example, we can use a bold font. The code is as follows:

h2 {
  font-weight: bold;
}

The font style can be set using the "font-style" attribute. Font styles usually have options such as "normal" (normal), "italic" (italic) and "oblique" (italic). For example, we can use italic fonts. The code is as follows:

em {
  font-style: italic;
}

As we have seen in this article, changing fonts in HTML can be achieved through CSS. CSS provides a variety of font properties, allowing us to comprehensively and flexibly control the appearance of fonts. In actual development, we should use common Web fonts as much as possible to ensure the consistency and accessibility of web pages. At the same time, use different font attributes as needed to make the web page look more beautiful and easier to read.
