Yes, you can apply a transparent black color overlay to a CMS image in Webflow. While the opacity option is available in the Style panel, you can achieve the desired effect using a combination of a div block and CSS properties.
First, make sure you have a div block wrapping your CMS image. If you don't have one, you can add a div block by selecting the CMS image, right-clicking, and choosing "Wrap with div block" from the context menu.
Once you have the div block, you can apply the transparent black color overlay by following these steps:
1. Select the div block that wraps your CMS image.
2. In the Style panel, click the Background button to open the background settings.
3. Choose a solid color for the background. You can create a transparent black color by adding an RGBA value. For example, you can use `rgba(0, 0, 0, 0.5)` for a black color with 50% opacity.
4. Adjust the opacity of the div block by adjusting the opacity slider in the Style panel. This will affect the opacity of both the background color and the CMS image inside the div block.
By adjusting the opacity slider, you can control the transparency of the entire div block, including the color overlay and the CMS image. This allows you to achieve the effect of a transparent black color overlay on the image.
Remember to test the effect in both the Designer and the live site preview to ensure it looks as desired.
