Do I need to create an interaction in Webflow to change the text and background color when hovering over a link block? If so, does the interaction generate CSS or JS?

To change the text and background color when hovering over a link block in Webflow, you do need to create an interaction. This can be done easily using the Webflow Designer without the need for any code.

Here's how you can create this interaction in Webflow:

1. Select the link block element you want to add the interaction to.
2. In the right sidebar, go to the "Interactions" tab.
3. Click on the "+ New Interaction" button to create a new interaction.
4. Choose the "Hover" trigger from the dropdown menu.
5. Select the element(s) you want to affect when hovering. In this case, you'll want to choose the text and background elements.
6. Click on the "Affect property" dropdown menu to choose the property you want to change. In this case, you'll want to select the text color and background color.
7. Choose the new color you want for the hover state.
8. Preview the interaction by hovering over the link block in the Webflow Designer.

The interaction you created in Webflow generates both CSS and JavaScript. The CSS is responsible for changing the visual properties like color, while the JavaScript handles the interactivity and triggering of the interaction.

This combination of CSS and JavaScript allows for a smooth and visually appealing hover effect on your link block without requiring you to write any code manually.

In summary, to change the text and background color when hovering over a link block in Webflow, you can easily create an interaction using the Webflow Designer. The interaction generates both CSS and JavaScript to achieve the desired hover effect.
