Basic HTML Code for WordPress »

You speak code? Great! WordPress offers two blocks for your coding-related needs.

The code block allows you to insert code snippets onto a page for instructional purposes. Using the code block, you can easily display almost any type of coding language for teaching or training.

You’ll see the code block on the HTML basics page.

The custom HTML block allows you to code a section of a page, much like the Classic Editor’s HTML tab. The block even allows you to preview the code right within the editor.

We recommend starting with blocks and using HTML only if you are confident with coding and familiar with the WashU Web Theme usage guidelines. The WashU Sites Support Team is unable to assist with issues caused by custom code.

Custom coding is risky!
