I'm positioning a modal div in the middle of the page with a max-height defined as a % of its container, in this case it shouldn't exceed 70% of the page height.
The contents of the div are two elements:
- A fixed height header div
- And a variable height content div
I want the modal to grow with the content until the max-height, then the content div should start scrolling. However whatever I do, the content seems to spill out of the modal like so:
This is my markup and styling:
body {
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.modal {
max-height: 70%;
border: 5px dashed green;
border-radius: 5px;
}
.container {
/* I cannot remove this container */
display: flex;
flex-direction: column;
width: 600px;
}
.header {
flex: none;
background: red;
height: 100px;
}
.content {
flex: 1;
background: yellow;
overflow: auto;
}
.big-stuff {
margin: 10px;
background: orange;
height: 600px;
}
<div >
<div >
<div >
Header
</div>
<div >
Content. Should shrink or grow to fit content but only to a max of the container height
<div >
Large content
</div>
</div>
</div>
</div>
Unfortunately I can't change the markup so I'm trying to get this working just by modifying CSS. If I remove the .container div, then everything seems to work but I was hoping there was another way.

CodePudding user response:
You can add flex to the modal, so that the content will not expand out of its parent (modal in this example):
.modal {
max-height: 70%;
border: 5px dashed green;
border-radius: 5px;
display: flex; /* Add this flex */
}
CodePudding user response:
Just add display:flex in the css to the modal class.
body {
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.modal {
max-height: 70%;
border: 5px dashed green;
border-radius: 5px;
display: flex;
}
.container {
/* I cannot remove this container */
display: flex;
flex-direction: column;
width: 600px;
}
.header {
flex: none;
background: red;
height: 100px;
}
.content {
flex: 1;
background: yellow;
overflow: auto;
}
.big-stuff {
margin: 10px;
background: orange;
height: 600px;
}
