Information relating to the presentation "Using Browser Tools to Manage Your LibGuides Appearance," by Loring Prest at SpringyFlash at the ACRL 2017 Conference in Baltimore.

Inspect Element

Inspection Tool is Part of:

  • Firefox (called "Inspect Element")
  • Chrome (called "Inspect")
  • Right-click a Web page element and choose the tool from the popup menu. Tool will open a window at the bottom of the browser.
  • Note: The separate inspection tool add-on, Firebug, is no longer being developed. Use the built-in inspection tools.


Useful for:

  • Analyzing HTML and CSS in Web pages
  • Identifying CSS rule (including selector name and property declaration) that is controlling behavior of a page element
    • This is necessary when you need to override CSS created by Springshare
  • Experimenting with variant settings in a live Web page
    • Inspect Element allows for direct changes to HTML and CSS
    • It is easy to try alternate colors, spacing, etc.
  • Altering Springshare CSS by adding Custom CSS in LibGuides Admin
    • Modified CSS can be copied and pasted into the Custom CSS
