Creating an overlay effect when users hover over an image is a nice easy way to add some interaction to your site.
Today I will show you how to create a very simple hover effect as well as a more ‘fancy’ solution. Both solutions will be done using nothing but CSS.
The Simple Overlay
A simple overlay effect is when the user hovers over an image and a transparent colour overlay appears.

The HTML
The CSS
As you can see not many lines of code are required at all. All I’ve done is put the image inside a div and given that div a background colour.
When I hover over the image, the image opacity will change to 0.2 giving the transparent overlay effect.
The Fancy Overlay
The second image overlay I want to show you is a little more ‘fancy’. Rather than just displaying a transparent overlay I want to slide the overlay up over the image and display more information.

The HTML
The first thing I do is add a container div called service-wrapper and set overflow to hidden so that I display the heading but hide the rest of the content. The div also needs to be set to position: relative so that I can use absolute positioning on other divs within this container div.
I then put the content in a container div called service-wrapper-inner. This div is positioned using absolute positioning, setting top: 185px and apply a background colour with an opacity of 0.9.
I’ve added transition: 0.1s so that I can control the animation speed when I change the div position from 185px to 0px. This will give a smoother transition effect.
To achieve the sliding up overlay effect all I need to do is add one line of css, so when I hover over the image the inner container div that contains our content will slide up to the top revealing the rest of the content that was hidden.
The CSS
