How to set font in css font

CSS is a style sheet language used for web design. It allows developers to more conveniently control the style and layout of web pages, including font settings. In this article, we’ll explore how to set CSS fonts to help you create beautiful, readable, and diverse web designs.

1. Basic knowledge of font settings

In CSS, fonts are usually defined by four attribute values: font family, font weight, italics and font size. They correspond to the four CSS properties of font-family, font-weight, font-style and font-size respectively.

1. Font family (font-family)

Font family refers to a collection of fonts, also called a font series. The text in the web page can use any fonts installed on the website, or use fonts installed on the user's computer.

In CSS, you can style text on a web page by specifying one or more font families. For example:

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

The above style indicates that the font family of the text content is set to Arial, which is a universal Western sans serif font. If the Arial font is not installed on the user's computer, the system will instead look for a sans-serif font, which is a general sans-serif font family such as Helvetica or Verdana.

2. Font-weight

Font-weight defines the thickness of the font. In CSS, the weight of a font can be specified as "normal" (default), "bold" (bold), or using a numerical value to specify the thickness. For example:

h1 {
  font-weight: 700;
}

The above style sets the font weight of the heading h1 to "700", which means it will be thicker.

3. Italic (font-style)

Italic defines whether the font is italic. In CSS, italics can be set with "normal" (default), "italic" (italic) or "oblique" (italic). For example:

em {
  font-style: italic;
}

The above style will render the em tags in the text with italic style.

4. Font-size

Font size refers to the size of the text. In CSS, font size can be specified using units such as pixels (px), percentage (%), em or rem (based on the relative size of the root element). For example:

p {
  font-size: 16px;
}

The above style sets the font size of the text to 16 pixels (px).

2. More font settings

In addition to font family, font weight, italics and font size, CSS also provides some other font settings for more detailed control.

1. Font style (font-style)

CSS provides the font-style attribute, which can respectively define whether the font is italic, whether it is normal, and whether it is italic . For example:

font-style: italic normal oblique;

2. Font variant (font-variant)

The font-variant attribute is used to control the variation of fonts, such as "small-caps" and "normal" etc. For example:

font-variant: small-caps;

3. Text-transform

The text-transform attribute is used to control the transformation style of text, such as "uppercase" and "lowercase" "(lowercase) etc. For example:

text-transform: uppercase;

4. Line-height

The line-height property is used to control the height of the text line. For example:

line-height: 1.5;

5. Letter-spacing

The letter-spacing property can increase or decrease the spacing between letters. For example:

letter-spacing: 2px;

3. Custom fonts

In CSS, you can not only use fonts already installed on your computer, but you can also add greater personality to the web page by using custom fonts. and diversity. Let's introduce how to use custom fonts.

1. Using @font-face

The @font-face rule allows you to use a custom font. You can load font files into CSS for use in web pages.

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

The above CSS code loads the MyFont font with the path "/fonts/myfont.ttf". Users need to download the font file before the text on the web page can be displayed correctly.

2. Specify font family

When you formulate @font-face rules, you need to specify the name of the font family. You can use this name to style text on your web page. For example:

h1 {
  font-family: "MyFont", sans-serif;
}

The above style sets the font of the text to MyFont, using the sans-serif font family if the user does not have MyFont installed.

4. Summary

CSS font is an important aspect of web design. It can help web developers control the appearance and presentation of web pages. By using properties such as font family, font weight, italics, and font size, as well as custom fonts and other CSS properties, you can create colorful web designs and provide users with a better reading experience.
