How can I reorder my divs with CSS?

2018-12-31 06:49发布

Given a template where the HTML cannot be modified because of other requirements, how is it possible to display (rearrange) a div above another div when they are not in that order in the HTML? Both divs contain data that varies in height and width.

<div id="wrapper">
    <div id="firstDiv">
        Content to be below in this situation
    </div>
    <div id="secondDiv">
        Content to be above in this situation
    </div>
</div>
Other elements

Hopefully it is obvious that the desired result is:

Content to be above in this situation
Content to be below in this situation
Other elements

When the dimensions are fixed it easy to position them where needed, but I need some ideas for when the content is variable. For the sake of this scenario, please just consider the width to be 100% on both.

I am specifically looking for a CSS only solution (and it will probably have to be met with other solutions if that doesn't pan out).

There are other elements following this. A good suggestion was mentioned given the limited scenario I demonstrated -- given that it might be the best answer, but I am looking to also make sure elements following this aren't impacted.

I was looking for a way to change the orders of the divs only for mobile version so then I can style it nicely. Thanks to nickf reply I got to make this piece of code which worked well for what I wanted, so i though of sharing it with you guys:

//  changing the order of the sidebar so it goes after the content for mobile versions
jQuery(window).resize(function(){
    if ( jQuery(window).width() < 480 )
    {
        jQuery('#main-content').insertBefore('#sidebar');
    }
    if ( jQuery(window).width() > 480 )
    {
        jQuery('#sidebar').insertBefore('#main-content');
    }
    jQuery(window).height(); // New height
    jQuery(window).width(); // New width
});

Just use flex for the parent div by specifying display: flex and flex-direction : column. Then use order to determine which of the child div comes first

I have a much better code, made by me, it is so big, just to show both things... create a 4x4 table and vertical align more than just one cell.

It does not use any IE hack, no vertical-align:middle; at all...

It does not use for vertical centering display-table, display:table-rom; display:table-cell;

It uses the trick of a container that has two divs, one hidden (position is not the correct but makes parent have the correct variable size), one visible just after the hidden but with top:-50%; so it is mover to correct position.

See div classes that make the trick: BloqueTipoContenedor BloqueTipoContenedor_VerticalmenteCentrado BloqueTipoContenido_VerticalmenteCentrado_Oculto BloqueTipoContenido_VerticalmenteCentrado_Visible

Please sorry for using Spanish on classes names (it is because i speak spanish and this is so tricky that if i use English i get lost).

As others have said, this isn't something you'd want to be doing in CSS. You can fudge it with absolute positioning and strange margins, but it's just not a robust solution. The best option in your case would be to turn to javascript. In jQuery, this is a very simple task:

$('#secondDiv').insertBefore('#firstDiv');

or more generically:

$('.swapMe').each(function(i, el) {
    $(el).insertBefore($(el).prev());
});

For CSS Only solution 1. Either height of wrapper should be fixed or 2. height of second div should be fixed

Here's a solution:

<style>
#firstDiv {
    position:absolute; top:100%;
}
#wrapper {
    position:relative; 
}

But I suspect you have some content that follows the wrapper div...
