I have a case that I can not solve, I'm developing a layout in HTML and CSS where I use flexbox centralizing content, well, on large screens everything works okay, but on small screen the div pops up and does not show the content that should show.
* {
margin: 0;
padding: 0;
font-family: Georgia, serif;
font-weight: normal;
font-size: 15px;
color: #333;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
html, body {
height: 100%;
width: 100%;
}
body {
background: #e9e9e9;
overflow: hidden;
}
div.content {
height: calc(100vh - 70px);
width: 100%;
display: flex;
justify-content: center;
align-items: center;
overflow-y: auto;
}
div.footer{
position: absolute;
bottom: 0;
width: 100%;
padding: 35px;
background-color: #FF4500;
