Issue Getting Div to Hug up close to another

问题

I have 6 Divs within a container Div. These divs have to be aligned a certain way for a clients needs. I've taken the basic layout for the customer website I'm working on and created a sample to be posted here. I have a regular CSS file and a mobile CSS file. When in mobile view the Divs will be aligned in sequential order 1-6. When in the regular view, Divs 1, 3, 4, and 5 will be aligned to the right. Divs 2 and 6 will be aligned to the left. I need div 6 to hug the bottom of div 2 with the exception of about 10px. With my current code the Divs have a huge gap between them and 6 gets pushed further down the page with the more content the right side Divs have. All of these Divs have dynamic content that can make them increase or decrease in the amount of shown content. How can I get Div 6 to ignore the right side Divs and hug Div 2 without screwing up how these condense and appear in mobile? (You can just resize your browser window for the mobile version to appear with this code.)

Here is my HTML and CSS:

回答1:

A floated element will move as far to the left or right as it can in the position where it was originally(this is important #1).

So put in this way:

We have 2 div

<div class="div5">div5</div>
<div class="div6">div6</div>

.div-blue{
    width:100px;
    height:100px;
    background: blue;
}

.div-red{
    width:50px;
    height:50px;
    background: red;
}

without float they'll be one below the other

If we float: right the div5, the div6 be positioned on the line when it was the div5,

/*the lines are just for illustrate*/

So if now we float: left the div6 it will move as far to the left as it can, "in this line" (see #1 above), so if div5 change its line, div6 will follow it.

Now let's add other div into the equation

<div class="div4">div4</div>
<div class="div5">div5</div>
<div class="div6">div6</div>

.div-gree{
    width:150px;
    height:150px;
    background: green;

    float:right;
}

We have this

If we set clear: right to the div5, we are force it to take the line bellow div4

So there you have why happens. Here the jsfiddle where I code this

NOW, HOW TO FIX IT

Just remove the float for the <div id="div6"> and set display: inline-block

like this:

#div6 {
    border: 1px solid pink;
    background-color: pink;
    margin-bottom: 10px;
    width: 65%;

    /*float: left;*/    /*removed*/

    display: inline-block;  /*added*/
}

This will keep the normal behavior for elements without float (The elements after the floating element will flow around it.). The display: inline-block is for your case to maintain the margin of div2.

HERE A JSFIDDLE EXAMPLE WORKING FOR YOUR CASE

I hope this helps now and in the future :)

回答2:

You'll need some javascript for this:

window.onload = function(){
    var d6Id = document.getElementById( 'div6' ); 
    var d6distanceTop = d6Id.offsetTop; // Get height above div 6

    var d2height = document.getElementById( 'div2' ).clientHeight; // Get height of div 2

    var space = d6distanceTop - 30 - d2height; // 30 for padding top and bottom + 10px margin

    d6Id.style["margin-top"] = "-"+space+"px";
}
