I am trying to make a container that holds some text and images, and starts out at a certain size, say 48px. Upon clicking I want the container to grow to fit the contents, and on a second click reshrink down to 48px. The main issue is I don't want to set the height for the full size container, I would like the container to automatically resize to fit the content.
I have figured out how to start the blog at full size, shrink and regrow, but I can't figure out a way to have it start small, grow, and shrink again.
const hoistingId = document.getElementById('hoisting')
function enlargeBlogItem() {
if(hoistingId.style.height===''){
hoistingId.style.height = '3rem';
} else {
hoistingId.style.height = '';
}
}
hoistingId.addEventListener('click', enlargeBlogItem)
You can use overflow: hidden; on the parent element to ensure that the child elements are inside the parent and not overlapping and then use a JavaScript function to handle the size changes. Attribute attr-small is used to store the original value of height. By removing the height attribute from the style of the parent it will default to wrapping the children.
function toggleSize(el){
const originalSize = el.getAttribute('attr-small');
if(el.style.height === originalSize) {
el.style.removeProperty('height');
} else {
el.style.height = originalSize;
}
}#container {
border: 1px solid;
width: 200px;
overflow: hidden;
}
#container:hover {
cursor: pointer;
}
.foo {
width: 90px;
height: 90px;
background-color: red;
display: inline-block;
margin-left: 5px;
margin-top: 5px;
}<div id='container' onclick='toggleSize(this)' attr-small='48px' style='height:48px;'>
<div class='foo'></div>
<div class='foo'></div>
<div class='foo'></div>
<div class='foo'></div>
<div class='foo'></div>
<div class='foo'></div>
</div>
