[css] Aligning two divs side-by-side

I have a small problem. I am trying to align two divs side by side using CSS, however, I would like the center div to be positioned horizontally central in the page, I achieved this by using:

#page-wrap { margin 0 auto; }

That's worked fine. The second div I would like positioned to the left side of the central page wrap but I can't manage to do this using floats although I'm sure it is possible.

I would like to push the red div up alongside the white div.

Here is my current CSS concerning these two divs, sidebar being the red div and page-wrap being the white div:

#sidebar {
    width: 200px;
    height: 400px;
    background: red;
    float: left;
}

#page-wrap {
    margin: 0 auto;
    width: 600px;
    background: #ffffff;
    height: 400px;
}

This question is related to css css-float

The answer is


I don't understand why Nick is using margin-left: 200px; instead off floating the other div to the left or right, I've just tweaked his markup, you can use float for both elements instead of using margin-left.

Demo

#main {
    margin: auto;
    width: 400px;
}

#sidebar    {
    width: 100px;
    min-height: 400px;
    background: red;
    float: left;
}

#page-wrap  {
    width: 300px;
    background: #0f0;
    min-height: 400px;
    float: left;
}

.clear:after {
    clear: both;
    display: table;
    content: "";
}

Also, I've used .clear:after which am calling on the parent element, just to self clear the parent.


The easiest method would be to wrap them both in a container div and apply margin: 0 auto; to the container. This will center both the #page-wrap and the #sidebar divs on the page. However, if you want that off-center look, you could then shift the container 200px to the left, to account for the width of the #sidebar div.


This Can be Done by Style Property.

<!DOCTYPE html>
<html>
<head>
<style> 
#main {

  display: flex;
}

#main div {
  flex-grow: 0;
  flex-shrink: 0;
  flex-basis: 40px;
}
</style>
</head>
<body>

<div id="main">
  <div style="background-color:coral;">Red DIV</div>
  <div style="background-color:lightblue;" id="myBlueDiv">Blue DIV</div>
</div>

</body>
</html>

Its Result will be :

Enjoy... Please Note: This works in Higher version of CSS (>3.0).


It's also possible to to do this without the wrapper - div#main. You can center the #page-wrap using the margin: 0 auto; method and then use the left:-n; method to position the #sidebar and adding the width of #page-wrap.

body { background: black; }
#sidebar    {
    position: absolute;
    left: 50%;
    width: 200px;
    height: 400px;
    background: red;
    margin-left: -230px;
    }

#page-wrap  {
    width: 60px;
    background: #fff;
    height: 400px;
    margin: 0 auto;
    }

However, the sidebar would disappear beyond the browser viewport if the window was smaller than the content.

Nick's second answer is best though, because it's also more maintainable as you don't have to adjust #sidebar if you want to resize #page-wrap.


The HTML code is for three div align side by side and can be used for two also by some changes

<div id="wrapper">
  <div id="first">first</div>
  <div id="second">second</div>
  <div id="third">third</div>
</div>

The CSS will be

#wrapper {
  display:table;
  width:100%;
}
#row {
  display:table-row;
}
#first {
  display:table-cell;
  background-color:red;
  width:33%;
}
#second {
  display:table-cell;
  background-color:blue;
  width:33%;
}
#third {
  display:table-cell;
  background-color:#bada55;
  width:34%;
}

This code will workup towards responsive layout as it will resize the

<div> 

according to device width. Even one can silent anyone

<div>

as

<!--<div id="third">third</div> --> 

and can use rest two for two

<div> 

side by side.
