I have been trying to place some tags on the top: 0px of some divs.
My problem is, that when I put "top: 0px", it does not place my to the top of the parent div.
I have been searching for some info about this, and it seems to be a "Collapsing Margin" problem..
I have tried to fix it by myself, but I can't fix it without keeping the main structure (main class centered.. header with width 100%.. etc..)
header {
display: flex;
justify-content: space-between;
align-items: center;
padding: 10px 50%;
background-color: grey;
position: fixed;
top: 0px;
width: 100%;
height: 50px;
z-index: 1000;
}
.topzone {
margin-top: 50px;
display: flex;
align-items: center;
justify-content: center;
}
.main {
margin: 0 auto;
display: flex;
align-items: center;
flex-direction: column;
max-width: 950px;
}
.inside-main {
background-color: white;
width: 100%;
height: 375px;
}
.inside-title {
justify-content: center;
text-align: center;
width: 75%;
margin: 0 auto;
}
.inside-content {
display: flex;
flex-wrap: wrap;
justify-content: center;
text-align: center;
width: 75%;
margin: 0 auto;
}
.inside-content div {
position: relative;
width: 30%;
margin: 0px 10px 0px 10px;
}
.inside-content img {
width: 100%;
}
.inside-content div h3 {
position: absolute;
top: 0px;
width: 100%;
}
<header>
<div>
<button id="login">1</button>
<button id="signin">2</button>
</div>
</header>
<div class="topzone">
<h1>TOP ZONE TITLE</h1>
</div>
<div class="main">
<div class="inside-main">
<div class="inside-title">
<h1>INSIDE TITLE ZONE</h1>
</div>
<div class="inside-content">
<div>
<img src="https://etc.usf.edu/clipart/21900/21988/square_21988_md.gif" alt="Just a box">
<h3>Box 1</h3>
</div>
<div>

<h3>Box 3</h3>
</div>
<div>
<img src="https://etc.usf.edu/clipart/21900/21988/square_21988_md.gif" alt="Just a box">
<h3>Box 4</h3>
</div>
<div>
<img src="https://etc.usf.edu/clipart/21900/21988/square_21988_md.gif" alt="Just a box">
<h3>Box 5</h3>
</div>
<div>
<img src="https://etc.usf.edu/clipart/21900/21988/square_21988_md.gif" alt="Just a box">
<h3>Box 6</h3>
</div>
</div>
</div>
In this example, the Box1, Box2, etc.. Should be in the same height of the top line of every box.
Thanks
Because H3 having default top and bottom margin. I just added margin: 0 in H3 css and update your code. I hope it'll help you out. Thanks
