To remove the default greyish gradient styling from a select element in Webflow, you can use custom code to override the default styles. Here's the process:
1. Identify the class or ID of the select element you want to style. You can find this information by selecting the element in the Webflow Designer and looking at the right-hand sidebar.
2. Once you have the class or ID, go to the Custom Code section in the Webflow Designer. Click on the "Head" tab to add code to the head tag of your site.
3. Add the following CSS code to the head tag:
```css
```
Make sure to replace `.your-class` with the actual class or ID of your select element. You can also replace `your-desired-color` with the specific color you want to use.
4. Update your site to apply the changes. Preview your site to see the updated styling for the select element without the default greyish gradient.
Keep in mind that by modifying the default styling of form elements, you may also need to adjust the styles for states like hover, focused, and disabled to ensure a consistent and user-friendly experience.
