Trying to create a webpage with a fixed height 'header' div followed by a 'content' div below it. The content div contains various other divs with actual page content, generating dynamically through PHP resulting in varying heights for different screens and users.
If that explanation is unclear, check out what I've accomplished so far: https://codepen.io/anon/pen/ZJPgWm (the code might look messy as it's a quick imitation of my real project).
#main {
width: 90%;
min-width: 400px;
max-width: 1200px;
height: calc(100vh - 10px);
margin-left: auto;
margin-right: auto;
position: relative;
overflow: hidden;
display: flex;
flex-direction: column;
}
#head {
background-color: blue;
font-size: 3vh;
}
#content {
background-color: red;
flex-grow: 1;
display: flex;
}
#left {
width: calc(16% - 6px);
float: left;
background-color: green;
}
#inner {
font-size: 10vh;
flex-grow: 1;
width: calc(84% - 6px);
float: left;
margin-left: 8px;
margin-bottom: 10px;
flex-grow: 1;
overflow-x: hidden;
overflow-y: auto;
background-color: yellow;
}<body>
<div id="main">

</body>The issue arises on Firefox and MS Edge where the overflowing content in #inner div gets cut off instead of showing a scroll bar like in Chrome. Reason appears to be in how the browsers handle height setting within the elements near its boundaries.
Looking for a solution that makes all browsers behave like Chrome. Also seeking clarification on which browser behavior is correct and the differences between them.
Aiming to avoid using JavaScript if possible. Any guidance or assistance is appreciated.
