Having an issue with Bootstrap icons displaying as blank boxes across all browsers

It seems to be a similar issue to what's discussed here:

Glyphicons rendering as empty box

Despite my efforts to search for solutions online, I can't figure out what the problem is. It all began when I first started using bootstrap. I've even tried reinstalling fonts from the website, but that didn't resolve the issue.

Most fixes I came across are related to specific projects, but the problem persists across all browsers in my case. While some glyphicons show up properly like on http://getbootstrap.com/components/, there are still elements that are not displaying correctly. Help me solve this issue!

EDIT: I don't have my own website, but rather notice this problem on various sites utilizing bootstrap (I think). It appears that certain fonts or elements are showing up as square boxes instead of rendering properly. I believe this started happening when I began using bootstrap for web projects.

Answer №1

When working with Bootstrap, it assumes that the icon font files are located in the ../fonts/ directory relative to the compiled CSS files. If you need to move or rename these font files, there are three ways to update the CSS:

1. Adjust the @icon-font-path and/or @icon-font-name variables in the source Less files. 2. Use the relative URLs option provided by the Less compiler. 3. Update the url() paths in the compiled CSS.

Ensure that the path to your icons is correctly set up in the directory.

It's important to define your icons with the aria-hidden attribute as well.

Modern versions of assistive technologies will announce CSS-generated content and specific Unicode characters. To prevent unintended output in screen readers, especially when icons are used for decoration purposes, they should be hidden using the aria-hidden="true" attribute.

<span class="glyphicon glyphicon-search" aria-hidden="true"></span>

If you share a link to your site, I can take a look and see exactly what might be happening.

Answer №2

To locate the glyphicons.less file within the Less directory, review the following instructions:

// Locate and include the fonts
@font-face {
  font-family: 'Glyphicons Halflings';
  src: url('@{icon-font-path}@{icon-font-name}.eot');
  src: url('@{icon-font-path}@{icon-font-name}.eot?#iefix') format('embedded-opentype'),
       url('@{icon-font-path}@{icon-font-name}.woff2') format('woff2'),
       url('@{icon-font-path}@{icon-font-name}.woff') format('woff'),
       url('@{icon-font-path}@{icon-font-name}.ttf') format('truetype'),
       url('@{icon-font-path}@{icon-font-name}.svg#@{icon-font-svg-id}') format('svg');
}

If your font files are located in the same folder as glyphicons, simply replace @{icon-font-name} with the name of your font for it to function correctly.

For example, you can use this syntax:

src:url('@{icon-font-path}myfont.eot');
