LibGuides is built upon Bootstrap, a framework of CSS, JavaScript, and HTML. Librarians can increase the usability and functionality of their guides with Bootstrap’s components without the need of extensive web development experience.
Glyphs that convey meaning that isn't otherwise communicated beyond the glyph will need further information for screen readers. For instance, the examples above have <p class="sr-only"> tag that provides information about the glyph.
