A filter is a visual effect that can be applied to an element. While most commonly used to manipulate the appearance of images and text, filters can be applied to any kind of element on the page.
If you are applying a filter to an image, note that the original asset in your media library will be unaffected. The filter is only applied to the image as it appears in the context of your website, not to the source image itself.
To open the Filters Panel, click the icon in the right toolbar, select it from the "Window" dropdown, or press <shift>-F on your keyboard.
Each filter has a value that can be set using a dropdown slider, or you can type a value directly into the text input.
Note that if you apply a filter to an element, the filter will also apply to any elements contained within it. So for example, if you place a text element inside a container element with a background image and apply a filter to the container, the filter will also be applied to the text.
