[css] Bootstrap 3 unable to display glyphicon properly

I am migrating from bootstrap 2.3 to bootstrap 3 and everything works well. But when I tried to add some icons, the icon font doesn't displayed properly. I tried to look over here http://bootply.com/61521 and only '.glyphicon-envelope' was being displayed properly. Others have displayed like 'E001' and so on.

How can I be able to solve this problem?

For other browsers, glyphicons are displayed properly, only firefox was unables to display it properly.

you can use tag like this:

<i class="fa fa-edit"></i>

make sure the name of the folder that contains the font name is "fonts" not "font"

This is the official documentation supporting the above answers.

Changing the icon font location Bootstrap assumes icon font files will be located in the ../fonts/ directory, relative to the compiled CSS files. Moving or renaming those font files means updating the CSS in one of three ways: Change the @icon-font-path and/or @icon-font-name variables in the source Less files. Utilize the relative URLs option provided by the Less compiler. Change the url() paths in the compiled CSS. Use whatever option best suits your specific development setup.

Other than this one mistake the new users would do is, after downloading the bootstrap zip from the official website. They would tend to skip the fonts folder for copying in their dev setup. So missing fonts folder can also lead to this problem

Just in case :

For example, I just tryed <span class="icones glyphicon glyphicon-pen"> and after one hour i realized that this icon was not included in the bootstrap pack !! While the enveloppe icon was working fine..

Hope this helps

First of all, I try to install the glyphicons fonts by the "oficial" way, with the zip file. I could not do it.

This is my step-by-step solution:

1. Go to the web page of Bootstrap and then to the "Components" section.
2. Open the browser console. In Chrome, Ctrl+Shift+C.
3. In section Resources, inside Frames/getbootstrap.com/Fonts you will find the font that actually is running the glyphicons. It's recommended to use the private mode to evade cache.
4. With URL of the font file (right-click on the file showed on resources list), copy it in a new tab, and press ENTER. This will download the font file.
5. Copy another time the URL in a tab and change the font extension to eot, ttf, svg or woff, ass you like.

However, for a more easy acces, this is the link of the woff file.

Did you choose the customized version of Bootstrap? There is an issue that the font files included in the customized package are broken (see https://github.com/twbs/bootstrap/issues/9925). If you do not want to use the CDN, you have to download them manually and replace your own fonts with the downloaded ones:

https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.svg https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.woff https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.ttf https://netdna.bootstrapcdn.com/bootstrap/3.0.0/fonts/glyphicons-halflings-regular.eot

After that try a strong reload (CTRL + F5), hope it helps.

Here's the fix that worked for me. Firefox has a file origin policy that causes this. To fix do the following steps:

1. open about:config in firefox
2. Find security.fileuri.strict_origin_policy property and change it from ‘true’ to ‘false.’
3. Voial! you are good to go!

You will only see this issue when accessing a file using file:/// protocol

I ended up switching to Font-Awesome Icons. They are just as good if not better, and all you need to do is link in the font, happy days.

1. Try using CDN
2. Try setting Access-Control-Allow-Origin HTTP Header

the icons and the css are now seperated out from bootstrap. here is a fiddle that is from another stackoverflow answer

@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0-rc2/css/bootstrap-glyphicons.css");

Bootstrap 3 Glyphicons CDN

I had the same problem using a local apache server. This solved my problem:

For Amazon s3 you need to edit your CORS configuration:

<CORSConfiguration>
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

For me placing my fonts folder as per location specified in bootstrap.css solved the problem

Mostly its fonts folder should be in parent directory of bootstrap.css file .

I faced this problem , and researching many answers , if anyone still in 2015 faces this problem then its either a CSS problem , or location mismatch for files .

The bug has already been solved by bootstrap

As others have noted, there are some issues with the customizer.

I was having troubles with the glyphicons not showing either, as well as issues with the navbar layout.

I used the suggestion and uploaded the fonts from the full zip/overwrote the ones from the customized version and that fixed the icons issues.

I also pulled in the CDN CSS and javascript instead of my local copy from the CDN. This fixed my navbar issues.

So I recommend until you get the hang of Bootstrap, not to use the customized version since you might get some frustrating, unwanted results.
