Unclear of final design, but you might try this:
function abc() {
const sel = document.querySelector(".content");
sel.style.height = "300px";
sel.style.position = 'absolute';
sel.style.bottom = '0px';
}
Solution 1 :
Solution 2 :
You can use the transform: scaleY(val) and transform-origin: bottom to resize and from where your element.
.abc {
width: 80%;
margin: auto;
display: grid;
grid-template-columns: repeat(10, [col-start] 1fr);
grid-template-rows: repeat(8, [row-start] 1fr);
padding-top: 3.4em;
padding-bottom: 3.4em;
}
.img {
grid-column: col-start / span 8;
grid-row: row-start / span 6;
background-size: cover;
max-width: 1074px;
max-height: 200px;
background-color: #ee0;
}
.content {
grid-column: col-start 6 / span 6;
grid-row: row-start 2 / span 6;
background: #fff;
min-height: 100px;
border: 1px solid blue;
padding: 3em;
}
.bigger {
transform: scaleY(2);
transform-origin:bottom;

Problem :
I am trying to increase height of div on button click. I am facing an issue my div is increase from bottom (default behaviour). But I want my div bottom with remain contain. It show from top.
In my example I have two div yellow and white. On button click, I am increasing the height of white box. But it is increase from down direction. I need it grows from top.
Here is my code:

<div class="parent">
<div class="abc">
<div class="img"></div>

</div>
</div>
<button onclick="abc()">click</button>
<script>
function abc() {
document.querySelector(".content").style.height = "300px";
}
</script>
</body>

You have to find a way to “pin” the div in position at its bottom then it will grow as you want.
