The Bootstrap framework provides you Glyphicons for icon.
Bootstrap doesn’t include an icon library by default, but it has a handful of recommendations for you to choose from. While most icon sets include multiple file formats, we prefer SVG implementations for their improved accessibility and vector support.
### How to use
To use Bootstrap icon create a span tag with base class `glyphicon` and individual icon class.
Use it only on elements that contain no text content and have no child elements.
This is an example of the CSS classes that bootstrap provides for glyphicons. More of them is avalible <ahref='https://getbootstrap.com/docs/3.3/components/#glyphicons'target='_blank'rel='nofollow'>here</a>
`.glyphicon glyphicon-plus` This is bootstrap's plus/add icon.
Icon classes cannot be directly combined with other components. They should not be used along with other classes on the same element. Instead, add a nested `<span>` and apply the icon classes to the `<span>`.
**Only use icons on empty elements**
Icon classes should only be used on elements that contain no text content and have no child elements.
