如何在 bootstrap 3.0中使用象形文字

The icons (glyphicons) are now contained in a separate css file...

The markup has changed to:

<i class="glyphicon glyphicon-search"></i>

or

<span class="glyphicon glyphicon-search"></span>

Here is a helpful list of changes for Bootstrap 3: http://bootply.com/bootstrap-3-migration-guide

There you go:

<i class="glyphicon glyphicon-search"></i>

Btw. you can use this conversion tool, this will also update the code for the icons:

Include the fonts Copy over all the font files to a /fonts directory near your CSS.

1. Include the CSS or LESS You have two options for enabling the fonts in your project: vanilla CSS or source LESS. For vanilla CSS, just include the compiled CSS file from the /css in the repository.
2. For LESS, copy over the .less files from /less into your existing Bootstrap directory. Then import it into bootstrap.less via @import "bootstrap-glyphicons.less";. Recompile when ready.
3. Add some icons! After you've added the fonts and CSS, you can get to using the icons. For example, <span class="glyphicon glyphicon-ok"></span>

source

If yout download a customized bootstrap 3 distro you must:

1. Download the full distro from https://github.com/twbs/bootstrap/archive/v3.0.0.zip
2. Uncompress and upload the entire folder called fonts to your bootstrap directory. Put together with the other folders "css, js".

Example Before:

\css
\js
index.html

Example After Upload:

\css
\fonts
\js
index.html

If you're using less , and it's not loading the icons font you must check out the font path go to the file variable.less and change the @icon-font-path path , that worked for me.

Bootstrap 3 requires span tag not i

<span class="glyphicon glyphicon-search"></span>`

If you are using grunt to build your application, it's possible that during build the paths change. In this case you need to modify your grunt file like this:

copy: {
main: {
files: [{
src: ['fonts/**'],
dest: 'dist/fonts/',
filter: 'isFile',
expand: true,
flatten: true
}, {
src: ['bower_components/font-awesome/fonts/**'],
dest: 'dist/css/',
filter: 'isFile',
expand: true,
flatten: false
}]
}
},

This might help. It contains many examples which will be useful in understanding.

Download all files from bootstrap and then include this css

<style type="text/css">
@font-face {
font-family: 'Glyphicons Halflings';
src: url('/fonts/glyphicons-halflings-regular.eot');
}
</style>
