Answer 1

You don't have any image elements in your css (img)

Here is a CSS example for an opacity decrease while hovering over an element:

img{
opacity: 1;
}

img:hover{
opacity: 0.2;
}

Answer 2

Sample code.

 img{
    opacity: 3.0;
    }

img:hover{
opacity: 1.2;
}

Answer 3

You can use something like this. Image & text contained in link and when the link get hovered the image get low highlighted and the text be normal. And you can use position: absolute of you want the text to place somewhere in image.

 <a href="#">
        <img src="" alt="">
        <span>Text</span>
 </a>

the css

a {
    display: block;
}
a:hover img {
    opacity: 0.2;
}
