Set font css

In web design, setting fonts is a very important step. Through good font design, you can make web pages more beautiful, effectively convey information and improve user experience. This article will introduce how to set fonts in CSS, including font selection, application and layout.

1. Choose fonts

When choosing fonts, you need to consider many factors. First, the legibility of the font should be taken into consideration. Fonts with good legibility can make it easier for users to read the content on the web page, thus improving the user experience. It is recommended to choose fonts with clear type, neat strokes and appropriate spacing, such as Arial, Helvetica, Verdana, etc.

Secondly, the consistency of the font style and the website theme should also be considered. If the website style is more concise and elegant, it is recommended to choose Sans-serif fonts (such as Arial, Helvetica), and if the website theme is more traditional, you can choose Serif fonts (such as Times New Roman, Georgia).

In addition, when selecting fonts, you also need to consider the rendering of different fonts in different operating systems and browsers. For example, Pingfang fonts are more common in Mac OS systems, but have poor compatibility in Windows systems. In order to avoid font compatibility issues, you can choose more common fonts, such as Arial, Helvetica, Tahoma, etc.

2. Apply fonts

There are two main ways to apply fonts in CSS.

1. Specify the font through the font-family attribute

In CSS, you can specify the font through the font-family attribute. This property supports both the specification of a single font and the selection of multiple fonts. For example, in the following CSS code, the preferred font is Helvetica, and the alternative fonts are Arial and sans-serif:

body { 
    font-family: "Helvetica", Arial, sans-serif;
}

In this example, the browser will first try to load Helvetica, and if it cannot be loaded, it will try Arial is loaded, and eventually the sans-serif font is used if both fonts cannot be loaded.

2. Import fonts through @font-face

In addition to using the fonts that come with the system, you can also import custom fonts through @font-face. Although this method is more complicated, it can greatly improve the visual effect of the web page.

The specific operations are as follows:

(1) Define the font format

The font format needs to be converted into a format available for the Web. Commonly used web font formats include WOFF, WOFF2, TrueType, OpenType, etc. When defining a font format, you need to add a set of quotes between the font name and the file name.

@font-face {
    font-family: "MyFont";
    src: url("MyFont.ttf");
}

(2) Specify the font

Next, specify the font in the CSS file through the font-family attribute and include the @font-face file name just defined. As shown below:

body {
    font-family: "MyFont", Arial, sans-serif;
}

In this example, if the MyFont font is not installed in the local system when the user browses the website, the browser will automatically download, install and apply the font.

3. Typesetting fonts

In specific typesetting, the color, size, style, etc. of the fonts need to be taken into consideration. Below are some commonly used CSS properties for styling.

1. Set font size

You can set the font size through the font-size attribute. The attribute value can be a fixed-size pixel value or relative to the parent element. Relative value (such as percentage).

body {
    font-size: 16px;
}

2. Set font color

You can set the font color through the color attribute. The property value can be specified using a hexadecimal color value, an RGB value, or a color name.

body {
    color: #333;
}

3. Set font style

The font style can be controlled through the font-style attribute. Supported attribute values ​​include normal (default value), italic and oblique.

body {
    font-style: italic;
}

4. Set font thickness

The thickness of the font can be controlled through the font-weight attribute. The attribute value can be a number (such as 400, 700, etc.) or a keyword ( Such as normal, bold, etc.).

body {
    font-weight: bold;
}
