How to use css to set font style in html

In web design, font selection and settings are a very important part. Correct fonts can improve the readability and aesthetics of web pages, and also have a great impact on users' reading experience. Therefore, mastering the selection and setting methods of fonts in HTML and CSS is an essential skill for every web designer.

1. Selection of fonts in HTML

The font selection in HTML mainly adopts the "font-family" method. That is, you wrap the desired font names in font-family in your HTML document.

Fonts in HTML can be classified into the following categories:

1. Web page default font

For most web pages, the default font of the web page is the most common fonts, such as Arial, Verdana, Times New Roman, etc. We usually display the main content of the web page in the default font to ensure the compatibility and legibility of the page display.

2. Custom fonts

In addition to the default fonts built into the system, custom fonts can also be used in HTML. This is usually achieved by using the @font-face attribute, which allows you to upload custom font files to the server and then call them through code for use. However, you need to pay attention to copyright issues when using custom fonts and do not use unauthorized font files.

2. Font format in CSS

CSS is a cascading style sheet language that can specify fonts and font sizes more accurately and provide more flexible font style control.

We can specify the following font properties using CSS:

1. Font family

In CSS, we can use the font-family property to set the font. Similar to the font method in HTML, we can also use default fonts or custom fonts. The difference is that in CSS, multiple font families can be set, separated by commas, so that if one of the fonts is not available on the user's computer, other default fonts will be tried to be loaded.

For example:

font-family: Arial, Microsoft Yahei, sans-serif;

2. Font size

Font size It can be set through the font-size attribute, and the unit is pixels (px), or other units can be used, such as percentage (%), em, and rem. It is worth noting that the font size setting should try to adapt to devices with different resolutions and ensure that the font size is consistent under different resolutions.

For example:

font-size: 16px;

3. Font style

There are two font styles: italic and bold. Set through the font-style attribute and font-weight attribute.

For example:

font-style: italic;

font-weight: bold;

4. Font color

Font color can be set through the color attribute, which can be set in various ways such as hexadecimal color value, RGB value, RGBA value, HSL value, etc.

For example:

color: #333;

color: rgb(0, 0, 255);

5. Line spacing, character spacing and Text decoration

We can use the line-height attribute to set the line spacing, the letter-spacing attribute to set the character spacing, and the text-decoration attribute to set the text decoration.

For example:

line-height: 1.5;

letter-spacing: 1px;

text-decoration: underline;

Summary:

Fonts are an important part of web design. Correct font selection and setting can improve the user’s reading experience and enhance the beauty of the web page. Mastering the font setting method in HTML and CSS is an essential skill for every web designer. Design web pages that are both compatible and beautiful by properly choosing default fonts and using custom fonts, as well as setting font size, style, color, etc.
