Glyphicons Font Icons

All available icons

Includes over 250 font icons from Glyphicon Halflings. Glyphicons Halflings are generally paid, but their authors allow Bootstrap to use them for free

Let’s take a look at some icons

The methods used are also very Simple

For performance reasons, all icons require a base class and a class corresponding to each icon. Put the following code and it will work fine anywhere. Note that in order to set correct padding, be sure to add a space between the icon and the text.

Do not mix with other components

Icon classes cannot be used directly in conjunction with other components. They cannot co-exist with other classes on the same element. You should create a nested tag and apply the icon class to this tag.

Only works on elements with empty content

Icon classes can only be applied to elements that do not contain any text content or child elements.

Change the location of icon font files

Bootstrap assumes that all icon font files are located in the ../fonts/ directory, relative to the directory of the precompiled CSS files. If you change the location of the icon font file, then you need to update the CSS file by any of the methods listed below:

Modify @icon-font-path and/or @ in the Less source file icon-font-name variable.

Take advantage of the relative URL address option provided by the Less compiler.

Modify the url() address in the precompiled CSS file.

Just choose a method based on your own situation.

Icon Accessibility

Modern assistive technologies can recognize and speak CSS-generated content and specific Unicode characters. To prevent screen reading devices from grabbing unintentional and potentially confusing output (especially when the icon is purely decorative), we set the aria-hidden="true" attribute for these icons.

If you use an icon to express something (not just for decoration), please make sure that the meaning you want to express can be recognized by assistive devices, for example, include additional content and pass .sr- The only class allows it to visually show the hidden effect.

If the component you create does not contain any text content (for example, contains only an icon), you should provide other content to express the intent of the control, so that users can Users of assistive devices know their purpose. In this case, you can add an aria-label attribute to the control.

<span class="图标的类" aria-hidden="true"></span>，图标的类就是图标下面的英文字母

还有如果想让图标变成其他颜色的话，自己写个css样式就好

The problem I encountered when using the icon: I used the icon, but an error occurred in the browser debugging window, which is that there is no such icon in the fonts directory. , but the fonts directory was downloaded from the website without any changes. The icons are displayed normally and there is nothing wrong. However, the icons sometimes load very slowly and sometimes cannot be displayed. If anyone knows the reason, please let me know.
