How to horizontally center a <div>? (104 answers)

Closed 2 years ago.

I've got an problem. I have the html code like this:

<div id="main_content" >
    <div id="container">
    </div>
</div>

The css like this:

#main_content {
    top: 160px;
    left: 160px;
    width: 800px;
    min-height: 500px;
    height: auto;
    background-color: #2185C5;
    position: relative;
}

#container {
    width: auto;
    height: auto;
    margin: 0 auto;
    padding: 10px;
    position: relative;
}

I suppose that the #container will be centered within #main_content. However, it is not. I just want to find out the reason and how to make it centered.

Answer 1

if you don't wanna set a width for #container just add

text-align: center; 

to #main_content

Answer 2

You must assign a width to the div you want to center.

Like This:

#container {
    width: 500;
    margin: 0 auto;
    padding: 10px;
}

Answer 3

it would work giving the #container div width:80%[any width less than the main content and have given in % so that it manages well from both left and right] and giving margin:0px auto; OR margin:0 auto; [both works fine].

Answer 4

#main_content {    
    width: 400px; margin: 0 auto;
    min-height: 300px;
    height: auto;
    background-color: #2185C5;
    position: relative;
}

#container {
    width: 50%;
    height: auto;
    margin: 0 auto;background-color: #ccc;
    padding: 10px;
    position: relative;
}

Answer 5

I have used the following method in few projects

https://jsfiddle.net/u3Ln0hm4/

.cellcenterparent{
  width: 100%;
  height: 100%;
  display: table;
}

.cellcentercontent{
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}

Answer 6

Make the css this way...

#main_content {
    top: 160px;
    left: 160px;
    width: auto;
    min-height: 500px;
    height: auto;
    background-color: #2185C5;
    position: relative;
 }

#container {
    height: auto;
    width: 90%;
    margin: 0 auto;
    background-color: #fff;
    padding: 10px;
}
