setAttribute( )

Sets an HTML attribute on the custom element's DOM node.

We can use setAttribute() to affect the custom element's definition and behavior. Consider setAttribute() a way for Velo to pass information to the custom element based on the context of the site.

Attributes can either be set:

• Using this API with setAttribute().
• In the Editor, by clicking the custom element's Set Attribute button, without any coding. Tip: Set attributes using the Editor if you would like to share the element with other designers that don't code.

Each setAttribute() function sets one attribute at a time using a key-value pair. Use multiple setAttribute() functions to set more than one attribute.

If the custom element does not yet have the attribute, setAttribute() creates it.
