How do I scale this layout?

Been working on this layout for some time now and each way I take I run into some sort of obstacle (v1 of this here: https://stackoverflow.com/questions/14572569/how-can-i-contain-pos-abs-div-within-specific-area)

What I'm trying to do now is to have the size of .spread adapt to the browser windows width and height, so it'll never exceed what the user currently can see in their browser (.spread currently have fixed width/height, for demo purposes). The ideal would to be able to resize on the fly and it adapts instantly (i.e. no media queries).

It works as it should in the v1 version I link to above, but then I had problems with the fade effect due to that .spread lacked an actual width/height.

Here's the new demo:

UPDATE: The markup can be changed as long as it works as described.

<div class="scrollblock" id="scroll_spread-1">
    <div class="action"><!-- --></div>
    <!--  -->       
</div>
<div class="scrollblock" id="scroll_spread-2">
    <div class="action"><!-- --></div>
    <!--  -->       
</div>

<div class="contentblock" id="spread-1">
    <div class="inner windowwidth windowheight">
        <div class="content">
            <span></span>
            <div class="spread">
                <div class="fade"><!-- --></div>
                <div class="left centerimage">
                    <img src="http://s7.postimage.org/8qnf5rmyz/image.jpg">
                </div>
                <div class="right centerimage">
                    <a href="#scroll_spread-2"><img src="http://s7.postimage.org/kjl89zjez/image.jpg"></a>
                </div>
            </div>  
        </div>  
    </div>  
</div>

<div class="contentblock" id="spread-2">
    <div class="inner windowwidth windowheight">
        <div class="content">
            <span></span>           
            <div class="spread">
                <div class="fade"><!-- --></div>
                <div class="left centerimage">
                    <a href="#scroll_spread-1"><img src="http://s7.postimage.org/5l2tfk4cr/image.jpg"></a>
                </div>
                <div class="right centerimage">
                    <a href="#scroll_spread-3"><img src="http://s7.postimage.org/fjns21dsb/image.jpg"></a>
                </div>
            </div>
        </div>  
    </div>  
</div>

}

.spread .left {
    position: relative;
    width: 50%;
    float: left;
    text-align: right;
    height: 100%;
}
.spread .right {
    position: relative;
    width: 50%;
    float: left;
    text-align: left;
    height: 100%;
}

div.centerimage {
    overflow: hidden;
}
div.centerimage img {
    max-width: 100%;
    max-height: 100%;
}

div.centerimage span {
    height: 100%;
    vertical-align: middle;
    display: inline-block;
}
div.centerimage img {
    vertical-align: middle;
    display: inline-block; 
}

P.S. The title is really bad, don't know what I'm looking for, but please change to something more informative if you can think of anything better.

maybe you could just pin your .spread divisor 

.spread {
  bottom: 11px;
  left: 11px;
  right: 11px;
  top: 11px;
  position: absolute;
  /* ... */
}

This way, it will be resized the same of the viewport area.

Here a jsFiddle to demonstrate.

Carry on

Have you considered using a responsive framework to solve your issue? You can set width's and heights to percentages and have min-width, min-height.

I know you were probably looking for a solely CSS/HTML solution, but really you're probably best off using some Javascript. There's no way to be clean and precise just using CSS & HTML. But if you run a tiny bit of JavaScript on page load and window-resize, then your divs can have actual height/width values and scale cleanly. The trick is to have the outside div get its width/height set by the JavaScript, and then all its children use % dimensions so they grow appropriately.

Here's the basics using some JQuery:

<script type="text/javascript">
//Function to get the current window dimensions.
function get_window_dims() {
    var dims = [];
        if (parseInt(navigator.appVersion)>3) {
            if (navigator.appName=="Netscape") {
                dims[0] = window.innerWidth;
                dims[1] = window.innerHeight;
            }
            if (navigator.appName.indexOf("Microsoft")!=-1) {
                dims[0] = document.body.offsetWidth;
                dims[1] = document.body.offsetHeight;
            }
        }
    return dims;
}
function ResizeDivs {
    var dims = get_widnow_dims();
    var div_width = Math.floor(dims[0] * 0.93); // calculating the div width to be 93% of the window width
    $('div.spread').css('width',div_width+'px');
}
$(function() {
    ResizeDivs();
    $(window).resize(function(){
         ResizeDivs();
    });
});
</script>

You could easily clean up this code to be more concise, but I figured I'd put it out here this way for you to see all the parts. If you wanted to spend the extra time, you could even add more JQuery to animate the divs when the window resizes.

Hope this helps.

Three-Quarters of the Way to a Full Solution

This is not quite a full solution yet, as it cannot accommodate a super narrow width window size (like your old version did). However, it is a good step toward what you seek.

Here is the example.

The key things that have been changed:

Added

.spread { height: 93%; } /* You had originally wanted a height difference */

Removed

  • overflow: hidden from div.centerimage.
  • width: 50% from .left and .right.
