css set page font

CSS is a language used to style web pages, making them more beautiful and easier to read. Among them, font settings are one of the most commonly used and important parts of CSS, because appropriate font settings can improve the readability and visual effects of the website. This article will explore how to use CSS to set the font of the page.

1. Font family and font

In CSS, font family (font-family) refers to the font family used in the website. For example, we can set the font family to "Arial, sans-serif", which means that if the Arial font is not installed on the user's computer, the CSS will try to use the system's default sans-serif font.

Font (font) refers to the specific attributes of the font, including font series, font size, font thickness, font style (such as italics), etc. The following are some commonly used CSS font properties:

1. font-family: font name or font family.
2. font-size: Font size, you can use px, em, rem units or percentage of relative size.
3. font-weight: The weight of the font, which can be normal (default), bold or a numeric value (100-900).
4. font-style: Font style, which can be normal (default), italic or oblique.

2. How to set the page font

In CSS, there are the following three methods to set the font:

1. Use @font-face to import customization Font:

@font-face {
font-family: custom-font;
src: url('path/to/font.woff2') format('woff2') ;
}

body {
font-family: custom-font, sans-serif;
font-size: 16px;
}

In this example , "custom-font" is the font family we defined, which refers to the font file with the path "path/to/font.woff2". This font is then applied to the body element and the default font is set to sans-serif.

2. Use Google Fonts:

Google Fonts is a free online font library that offers hundreds of fonts to choose from. To use Google Fonts, add the following code in the head section of your HTML document:

Then apply the font to the element:

body {
font-family: 'Open Sans', sans-serif;
font-size: 16px;
}

3. Use the system default font:

If you want the page to use the system default font, you can use the following code:

body {
font-family: -apple-system, BlinkMacSystemFont, “Segoe UI”, Roboto, Oxygen-Sans, Ubuntu, Cantarell, “Helvetica Neue”, sans-serif;
font-size: 16px;
}

System default fonts tend to have good readability, so it is a good choice.

3. Adjust font size and line height

Font size and line height are two factors that affect readability. In CSS, you can use the following code to adjust font size and line height:

body {
font-size: 18px;
line-height: 1.6;
}

Among them, line-height refers to the ratio of line height to font size. Generally speaking, 1.4-1.6 is a good choice, which can make the page layout beautiful and easy to read.

4. Font weight and style

Font weight and style can also affect the readability and visual effect of the font. In CSS, you can use the following code to change the font's weight, style, or both:

body {
font-weight: bold;
}

p {
font-style: italic;
}

h1 {
font-weight: bold;
font-style: italic;
}

五,Conclusion

Through appropriate font settings, the readability, visual effects and user experience of the website can be improved. In the application, you can choose the appropriate font family, font size, thickness, style and line height according to the theme and target audience of the website, which can make the website more beautiful and easy to read, and provide users with a better reading experience.
