CSS- How to keep a Div always center to Window?

May 30, 2007

Usually we all want our main content window to keep floating in middle of window when user resize browser or change display resolution and here is the small trick I used in my website (http://www.lakkakula.com)

Logic in CSS goes like

#yourdivid {
width : x px;
position: relative;
left: 50%;
margin-left: -x/2 px;

For example your div id is container and width is 600px
#container {
width: 600px;
position: relative;
left : 50%;
margin-left: -300px;

    Your solution is not working with IE6 (test news.php on my website). Do you have a “IE6 friendly” solution?

    The Flash header sould be centered all the time (even if window width < Flash width).

    .Container {
    *text-align:center; /* if you want ie<6 to center, i usually leave this out*/
    .Main {
    *text-align:left; /* ‘*’ hides from smart browsers */
    _width:1000px; /* for ie ie<7 */
    /* semi stretchy layouts see. romack.net */

    I am not getting it,
    The first one works on Firefox.
    The second one doesn’t work at all?
    Can you please explain this more clearly?

    I think this is a better solution.

    #container {
    width: 600px,
    position: absolute;
    left : 50%;
    margin-left: -300px;

  5. I tend to use the solution:

    margin: 0 auto;

    It always works for me…

    Thanks for this – saved me hours:)

    The example has width: 600px, with a comma instead of width: 600px; which I think is a typo.

    Thanks Tom. Corrected it.

    well, hi admin adn people nice forum indeed. how’s life? hope it’s introduce branch ;)

  13. Omar Says:

    Nice. Will this center any nested divs as well or do you have to manually hard code each div on this page with this code?

  14. Mike Says:

    The combination of your blog and personal homepage have almost completely extinguished any hopes to be a good web-designer, lol. Very, very nice work!

  15. Ton Says:

    I use:
    margin-right: auto;
    margin-left: auto;

    and it works with all the browsers…

    Sorry if I am chimin’ in too late. The original solution isn’t just bulky but also incorrect. It only works if the winder is wider than then content. Try resizing the browser window to a width less than x. You simply start losing content on the left. margin 0 auto is exactly it.

    • gab Says:

      Thanks Igor – you hit the nail on the head with the lost content on left. Your margin: 0 auto is the best answer – even in finding this one year late!

  18. Emmanuel Says:

    The solution is fine depending on what you want, I always use:
    #container {

    to center any element

    But this blog was exactly what I was looking for, and it is useful if you’ve got a large header image for example that you want to stay centered even if the window is resized
