Image not stretching to full parent height? - html

Question

As you can see in the picture above, the image on the right side is somehow not stretching to the full parent height. Why is this and how can I, without defining a specific height for the parent, always make sure that the image stays on the very edges of the parent? That is, without using background-size: cover; or any CSS pertaining to removing the img tag.

I will be happy to assist anyone further in clarifying this question!

Answer 1

The answer was found due to a new perspective of things: instead of seeing that the child didn't stretch to the parent. I thought why the parent went beyond the child. And thanks to the wonderful #PeeHaa, I was able to find an answer.
The img tag is an inline element, making it display: block; will suffice, and the child will stay within the designated perimeter (parent).
Good luck to you all, and happy coding!

Answer 2

Maybe you would like to remove the image tag and have the image as the background of the .scheme-img div. You can set background-size:cover to have the image covering all edges. Please note that this solution may cause blurry image if the image isn't large enough that it has to be enlarged to fit the .scheme-img div.
Btw, i can't seem to see why you have to add both .hero-img and .scheme-img tags to the div. If it is not needed, you are suggested to simplify it.

Answer 3

What about adding below CSS and removing your <img> tag? -
.hero-img {
background:url('/assets/img/about-us1.jpg');
background-size:cover;
}
Note: Above will cover your entire div having hero-img class with the image you want, edge-to-edge. But it comes with a caution that your div's size may change depending on the device screen size and also image may be of different aspect ratio than your div so in those cases stretching the image will make it lose its aspect ratio.

Answer 4

This will work.
You can use JavaScript. Here is your code. But before this please create an id of your img tag and place it's value as img. Also, create an id of the div whose size height you want to set as the the height of your image and place it's value as y .
<script>
var a = document.getElementById("y");
var b = document.getElementById("img");
var c = a.offsetHeight +"px";
b.style.height = c;
</script>
