Hi @akcumeh. To overlay the image you need to ad one more <div> element to de img container, like this
<div class="img01-div col-lg-6">
<img src="images/image-header-mobile.jpg" class="img01" alt="">
<div class="overlay"></div>
</div>
You need to add another for the img02 too
<div class="img02-div col-lg-6">
<img src="images/image-header-mobile.jpg" class="img02" alt="">
<div class="overlay"></div>
</div>
Now add some css properties. In your .css file would look like
.img01-div, .img02-div {
margin: 0;
padding: 0;
border-radius: 15px 15px 0 0;
position:relative; /*add this property*/
}
.overlay {
/* absolute position of the overlay, relative to its container*/
position: absolute;
top: 0;
left: 0;
/* give it the size of its container*/
width: 100%;
height: 100%;
/*and give it colour and transparency*/
background-color: hsl(277, 64%, 61%);
opacity: 0.6;
}
Remember to add border-radius property too!
