How to put spacing between floating divs?

i have a parent div, which can change its size, depending on the available space. Within that div, i have floating divs. Now, i would like to have开发者_如何学JAVA spacing between these divs, but no space to the parent div (see drawing).

Is there a way to do this with CSS?

Thank you

I found a solution, which at least helps in my situation, it probably is not suitable for other situations:

I give all my green child divs a complete margin:

margin: 10px;

And for the surrounding yellow parent div i set a negative margin:

margin: -10px;

I also had to remove any explicit width or height setting for the yellow parent div, otherwise it did not work.

This way, in absolute terms, the child divs are correctly aligned, although the parent yellow div obviously is set off, which in my case is OK, because it will not be visible.

You can do the following:

Assuming your container div has a class "yellow".

.yellow div {
    // Apply margin to every child in this container
    margin: 10px;
}

.yellow div:first-child, .yellow div:nth-child(3n+1) {
    // Remove the margin on the left side on the very first and then every fourth element (for example)
    margin-left: 0;
}

.yellow div:last-child {
    // Remove the right side margin on the last element
    margin-right: 0;
}

The number 3n+1 equals every fourth element outputted and will clearly only work if you know how many will be displayed in a row, but it should illustrate the example. More details regarding nth-child here.

Note: For :first-child to work in IE8 and earlier, a <!DOCTYPE> must be declared.

Note2: The :nth-child() selector is supported in all major browsers, except IE8 and earlier.

Add margin to your div style

margin:0 10px 10px 0;

I'm late to the party but... I've had a similar situation come up and I discovered padding-right (and bottom, top, left too, of course). From the way I understand its definition, it puts a padding area inside the inner div so there's no need to add a negative margin on the parent as you did with a margin.

padding-right: 10px;

This did the trick for me!

Is it not just a case of applying an appropriate class to each div?

For example:

.firstRowDiv { margin:0px 10px 10px 0px; }
.secondRowDiv { margin:0px 10px 0px 0px; }

This depends on if you know in advance which div to apply which class to.

A litte late answer.

If you want to use a grid like this, you should have a look at Bootstrap, It's relatively easy to install, and it gives you exactly what you are looking for, all wrapped in nice and simple html/css + it works easily for making websites responsive.
