How to use font icons in uniapp implementation

Uniapp is a cross-platform development framework based on the Vue.js framework. It can package applications into applications for multiple platforms such as Android, iOS, and Web at the same time. Using font icons in Uniapp is a very common requirement. This article will introduce in detail how to use font icons in Uniapp and provide corresponding code examples.

1. Preparation
Before starting, you need to prepare the font icon file you need to use. Common font icon libraries include Font Awesome, Iconfont, etc. You can download the corresponding font files (usually in .woff or .ttf format) through the official website. After the download is complete, place the font file in the project's static directory for reference in the application.

2. Introduce the font icon file
Introduce the font icon file into the App.vue file, and the font icon can be used globally. In the style tag of the App.vue file, add the following style code:

@font-face {
font-family: 'iconfont';
src: url('@/static/iconfont .woff') format('woff'), url('@/static/iconfont.ttf') format('truetype');
}
.iconfont {
font-family: "iconfont" ;
font-size: 16px;
font-style: normal;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
}

This code defines a font style named 'iconfont' and applies the font file to the font style.

3. Use the font icon

1. Use it in the template
   Where you need to use the font icon, use the i tag and add the class 'iconfont' to it, and at the same time Set a specific icon style for the class attribute.

<text class="iconfont icon-home"></text>

In the above code, An icon with class 'icon-home' is used, and the 'iconfont' class is used as the font style. You can replace the icon name with the corresponding class name according to the specific usage of the font icon library.

2. Used in styles
   You can use font icons in styles to achieve some special effects, such as using font icons in buttons.

<button class="btn">
  <text class="iconfont icon-search"></text>
  搜索
</button>
