I’m with a case where I can’t solve, I’m developing a layout in HTML and CSS where I use flexbox centering content, well, on large screens everything works ok, but on small screen to div burst 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;
}
/*div.container-menu {
    height: 100%;
    width: 750px;
    display: flex;
    justify-content: center;
    align-items: center;
}*/
div.menu {

Magichat, I’m having a hard time making my layout behave well when I resize in the browser to a smaller size, these 16 center div should all show up but when the browser this small 3 of them do not appear because of the centralized flexbox, this is my problem

Via css you can control the break-points, a tip is to use percentage instead of pixel in div, follow example:

@media screen and (max-width: 992px) {
  div.item-menu { 
      width: 33%;  
  }
}
