To work around this, you would either have to set explicit dimensions on the parent element ( height/ width), or you could remove the absolute positioning on the child img element. Thus, the background image doesn't show up. In doing so, it is removed from the normal flow, and since it was the only child element, the parent element therefore collapses upon itself and it doesn't have any dimensions. To set the opacity of a background image, you just need to add an opaque image as first image in the background-image set. Because it applies to everything behind the element, to see the effect you must make the element or its background at least partially transparent. In addition, the img element was absolutely positioned. The backdrop-filter CSS property lets you apply graphical effects such as blurring or color shifting to the area behind an element. This is why the z-indexs weren't working as expected. However, I am also using background-color: inherit on the pseudo-element, which means that, at any given moment, the pseudo-element, which is situated above its parent div (and therefore above the background-image of the div) is going to have the same background-color (meaning that the background-color of the pseudo-element is going to.

One of the simplest ways to add image or text overlay is using CSS properties and pseudo-elements. This option lets you set a color overlay on a background image in one property! This is my preferred method.As a side note, your example wasn't working for a couple of reasons. 1: To add a color overlay to the background images, first add a class for example. The final color is composed of the darkest values of each color channel. This blend mode is equivalent to hard-light but with the layers swapped. One of which is the original image, and the other a linear gradient. You can simply declare two background-images. The final color is the result of multiply if the bottom color is darker, or screen if the bottom color is lighter. I see that a lot of people here create an extra element or pseudo elements, but you dont need two elements to create this effect. I’ve also written a working example of these options on a CodePen. The effect is like two images shone onto a projection screen. I have to do it through css without the need for another div, to be absolute positioned over the image, with a white background and opacity setting changed. The other option is to have a background-color property set with whatever color your heart desires, plus background-blend-mode: multiply.īelow are a couple of sample snippets of these options in CSS.
