CSS: How to define a centered div with endless vertical borders and an initial height of 100%?_问答_开发者

First question on SOF, please be gentle if this may be a stupid question. :) Haven't found a solution, neither here nor on the web.

I got some trouble with CSS. I pasted my code at the end of this post but first Ill explain what I'm trying to accomplish:

I want to build a centered fixed-width content area with endless vertical graphical borders to the left and right.

This is what I tried:

I created a #content div with a .wrapper div inside. Standard procedure to center a div Id say. Gave the #content the background property for the left border and the .wrapper div the right background. #content works fine: endless left border. But .wrapper stays the same height as its content. So if there is less content then the browser-height the border won't be endless.
If I set the content heights to 100% the borders show till the bottom of the page, but if the content is higher then the browser height and I scroll down the borders don't continue.
I inserted another div between #content and .wrapper: #contentbr and gave that div the same propertys as #content but with the right border graphic: Won't work, the height stays the same as the content of the wrapper.

Tried some more minor tweaks but neither worked out the way I want it.

Sad thing is: Nr. 2 works fine if I set the background property of #content to this: _background: url(img/content_left.png) top left repeat-y, url(img/content_left.png) top right repeat-y;_

Sadly the IE doesn't know CSS 3 so this is no solution as I can't ignore the IE.. :(

So im hoping for some help of you guys. Someone has to know how to do this magic.

Important notice on my HTML & CSS example: I replaced the background-properties with border-properties. In reality the left and right borders need to be two different images and use the commented backround-properties!

HTML & CSS:

<!doctype html>
<html>
<head>
    <!-- <link rel="stylesheet" type="text/css" href="css/style.css"> -->
    <style type="text/css">
        html, body { height: 100%; }

        #content 
        {
            margin: 0 auto;
            width: 950px;

            /* this is the real deal: */
            /* background: url("img/content_left.png") top left repeat-y; */

            /* this is just for the example */
            border-left: 1px solid black;

            height: auto !important;
            height: 100%; /* IE 6 Workaround */
            min-height: 100%;
        }

        #content .wrapper
        {
            /* this is the real deal: */
            /* background: url("img/content_right.png") top right repeat-y; */

            /* this i开发者_JS百科s just for the example */
            border-right: 1px solid black;

            height: auto !important;
            height: 100%; /* IE 6 Workaround */
            min-height: 100%;

            padding: 0px 70px;
        }
    </style>
</head>

</body>
</html>

I removed the margin and padding from all elements to prevent the gap between document edge and border.

 * { margin: 0; padding: 0; }

To use the 100% height on the #wrapper as well as the #content div, use this:"

#content { position: relative } 
#wrapper { position: absolute }

This is what I get:

The min-height hack, as far as I know requires that you put the properties in the following order:

min-height: 100%;
height: auto !important;
height: 100%;

Maybe I'm wrong, but I was certain that was the only way around it.

If you've got a 100% height div in th center of the page why don't you create a repeating background that you can apply to the body, or the outer-most container that will repeat to the maximum size of the box possible?

Or, just use:

border: solid #000;
border-width: 0 1px;

on your outer div

Changed the layout a bit.

From .wrapper I removed all height information.

From #content I removed the height: auto !important; and outsourced the height: 100%; to

html #content { height: 100%; }

Just below #content and .wrapper

Now it works the way it should (even with graphical borders). Inital height of 100% and continuing borders if content exceeds window height:

html,
body {
  height: 100%;
}

#content {
  margin: 0 auto;
  width: 950px;
  /* this is the real deal: */
  /* background: url("img/content_left.png") top left repeat-y; */
  /* this is just for the example */
  border-left: 1px solid black;
  min-height: 100%;
}

#content .wrapper {
  /* this is the real deal: */
  /* background: url("img/content_right.png") top right repeat-y; */
  /* this is just for the example */
  border-right: 1px solid black;
  padding: 0px 70px;
}

* html #content {
  height: 100%;
}

<div id="content">
  <div class="wrapper">
