Web Inspector Basics

What is Web Inspector?

The Web Inspector is built into all modern browsers. The Web Inspector allows you to to see the exact CSS used to style different HTML elements.

These three basic steps will work in most current browsers to open the web inspector. If you’re using Safari or Microsoft Edge, you may need to activate the feature before you can use it.

To launch the Web Inspector:
  1. Right-click on a web page element (like text or an image)
  2. Select the “Inspect Element” option
  3. Look for a panel at the bottom or side of the screen

The panel will show the HTML for the element you clicked as well as all the CSS that applies to it. You can click on different HTML elements in the panel and then look at the CSS on the right to figure out what CSS can be copied.

In Safari:

  1. Go to Preferences and click on Advanced.
  2. Check the Show Develop menu in menu bar checkbox.

In Microsoft Edge:

  1. Enter about:flags in your Edge address bar.
  2. Check the box to Enable View mode and Inspect Element.

The Web Inspector is enabled by default in Google Chrome.

To add the copied code, go to My Sites → Appearance → Customize → Additional CSS to make design customizations on CSS.
