What could be causing the 'margin-top' property not to function as expected?

Although I understand the concept of 'margin-collapse', I am puzzled as to why there is no visible 10 px margin on the top of the first box here. The top box, which has the id 'first', should have a 10px margin above it. If this method is incorrect, what is the correct way to achieve this? And why does it not work as expected?

CSS:

#Main{
background-color: gray;
position: relative;
width: 200px;
height: 300px;  
}


.box{
position:relative;
height: 60px;
width: 175px;
background: black;
margin: 10px 10px 10px 10px;
}

HTML:

<div id="Main"> 
    <div id="first" class="box"></div>
    <div id="second" class="box"></div>
    <div id="third" class="box"></div>
</div>

I realize that one solution could be adding 10px padding to the parent div. But then again, why doesn't this method produce the desired result?

Answer №1

The margin: 10px 10px 10px 10px within your code is responsible for shifting the position of the "Main" box.
To specifically adjust the box with the id "first", utilize position:relative; top: 10px;

edit: While I cannot provide a definitive explanation, it seems likely that this occurs due to the default display property of the "Main" box being set to block. By changing it to display: inline-block;, the issue should be resolved. (View updated demo on jsfiddle)

Answer №2

When it comes to how browsers interpret the code, there seems to be a discrepancy in the expected result where a 10px gap should exist between the top of the child element and the outer parent. One workaround is to either add padding-top to the parent or assign overflow:auto; to the main div.

Check out the DEMO here: http://jsfiddle.net/kevinPHPkevin/2f4Kz/4/

#Main {
    background-color: gray;
    position: relative;
    width: 200px;
    height: 300px;
    overflow:auto;
}

Another solution is to create a transparent border around the main div to prevent margin collapsing:

#Main {
        background-color: gray;
        position: relative;
        width: 200px;
        height: 300px;
        border: thin solid transparent;
    }

The third and final option (to my knowledge) involves stopping margin collapsing by setting

padding-top: 1px; margin-top: -1px;
on the parent div:

#Main {
    background-color: gray;
    position: relative;
    width: 200px;
    height: 300px;
    padding-top: 1px;
    margin-top: -1px;
}
