How to Insert Shortcode Into a WordPress Page

1. Create a new WordPress page by opening the 'Pages' menu on the left side of the dashboard and selecting 'Add New.' Alternatively, click 'Pages' to view a list of existing pages, then click 'Edit' under the page that you want to insert. You can also add a shortcode to a post by using the 'Posts' section rather than the 'Pages' section.
2. Click the 'HTML' tab at the top of the page editing screen to view the HTML code for the page. Move the cursor to the location where you could like WordPress to trigger the shortcode.

3. Type the desired shortcode between a pair of brackets. For example, to use the built-in gallery shortcode, type '[gallery].'
4. Click the 'Publish' or 'Update' button at the top of the screen.
