I am very much confused here. Since the body is 100% (width/height) and main-container is also 100% (width/height), why is there vertical scroll?
I created a jsFiddle to explain the situation: http://jsfiddle.net/dcnnvgs1/1/
body,
html {
width: 100%;
height: 100%;
font-family: "Trebuchet MS !important";
background-color: #00b3b3;
}
.main-container {
display: flex;
flex-direction: column;
flex-wrap: nowrap;
height: 100%;
width: 100%;
box-sizing: border-box;
}
.main-header {
background-color: #099;
height: 10%;
}
.main-footer {
background-color: #099;
height: 10%;
}
.main-content {
background-color: #fff;
height: 100%;
}<body>
<div class="main-container">
<div class="main-header">HEADER</div>
<div class="main-content">jecechejbhcbjbcjrbjb bbjbhbbk</div>
<div class="main-footer">FOOTER</div>
</div>
</body>
