Adjust background size on hover - html

Question

When you hover over the image, you will see that it will be replaced by the semi-transparent background in my code.
The transparent background is supposed to cover all the picture, however, it only covers the area taken by the text.
How do I make sure that it covers the whole picture, regardless of the text within the box?

Answer 1

Remove display:table; from .text-content. Also add bottom:0; to it.

Answer 2

Remove display: table;, and for aligning the content vertically center use CSS Flexbox's align-content property.
Have a look at the snippet below:
/*Programs*/
ul.img-list {
list-style-type: none;
margin: 0;
padding: 0;
text-align: center;
}
ul.img-list li {

height: 100%;
margin: 0;
position: relative;
}
div.text-content {
background: rgba(26,33,43,0.9);
color: white;
cursor: pointer;
display: flex;
align-items: center;
