No content in a DIV element causing unusual height in IE7

Question

No content in a DIV element causing unusual height in IE7

UPDATE 1:

After some experimenting, I discovered that by removing the width:100% property from the div, I am able to achieve the desired outcome of having a height of 0 when the div is empty. However, I still require the div to have a width of 100%, which seems to be causing it to retain its height even without any content.

You can see the issue for yourself in this jsfiddle. To replicate the problem, try accessing the link using IE7 or possibly even IE6 and older versions.

ORIGINAL QUESTION:

I am facing an issue with an empty div that inexplicably has a non-zero height.

In Chrome, the div remains invisible unless it contains content. But in IE7, the div is displayed even when empty.

Essentially, I want the div to be 0px in height when it has no content, and to automatically adjust its height based on the content it holds. This behavior is only observed when the div does not have a width set to 100%.

Answer №1

Update following the discovery that you are utilizing position: fixed:

To cater to IE7 compatibility, it is necessary to employ two div elements. It appears there is no way around this requirement (unless opting for a single div with a JavaScript workaround).

Refer to:
Without content: http://jsfiddle.net/k7V2X/2/
Including content: http://jsfiddle.net/k7V2X/3/

The issue arises when specific properties like width: <not auto> or position: fixed are added, triggering hasLayout on the element. Once hasLayout is activated, the bug manifests.

Given the necessity of using position: fixed (..even though it's not supported in IE6, but let's move past that), circumventing

hasLayout</code is impractical, thus making this bug unavoidable.</p>

<p>Hence, I have proposed the most effective workaround available to address this issue.</p>

<hr>

<p><strong>Prior solution:</strong></p>

<blockquote>
  <p>However, I need the div to have a
  width of 100%</p>
</blockquote>

<p>Simply refrain from specifying <code>width: 100%

.

The div will then default to width: auto, taking up "the full available width". While width: auto differs from width: 100%, visually they appear similar based on the context of your question.

Confirm functionality on Chrome and IE6/7 (without content): http://jsfiddle.net/k7V2X/
Observe behavior on Chrome and IE6/7 (with content): http://jsfiddle.net/k7V2X/1/

This aligns with my interpretation of your inquiry and provides the desired outcome.

Answer №2

This issue caused by an irritating bug in Internet Explorer.

Previously, I have managed to work around it using the following CSS:

div{
    overflow:hidden;
    min-height:0;
    display: inline;   
}

For a demonstration, you can check it out here: http://jsfiddle.net/tomgrohl/YfbJt/

If your layout has been impacted by this bug, consider using a class that is added when content is dynamically inserted into the div:

div
{
    height:0;
    overflow:hidden;    
}

div.active
{
    height: auto;
}

Answer №3

It seems like IE 7 automatically assigns a default height to without user input.

You could experiment with setting the height to 0px and see how it affects the layout.

Start by incorporating the following code snippet at the top of your CSS stylesheet:

/* Utilize CSS reset from http://meyerweb.com/eric/tools/css/reset/
   Version 2.0 | Updated on 20110126
   License: Public domain
*/

html, body, div, span, applet, object, iframe,
h1, h2, h3, h4, h5, h6, p, blockquote, pre,
a, abbr, acronym, address, big, cite, code,
del, dfn, em, img, ins, kbd, q, s, samp,
small, strike, strong, sub, sup, tt, var,
b, u, i, center,
dl, dt, dd, ol, ul, li,
fieldset, form, label, legend,
table, caption, tbody, tfoot, thead, tr, th, td,
article, aside, canvas, details, embed,
figure, figcaption, footer, header, hgroup,
menu, nav, output, ruby, section, summary,
time, mark, audio, video {
    margin: 0;
    padding: 0;
    border: 0;
    font-size: 100%;
    font: inherit;
    vertical-align: baseline;
}
/* Reset HTML5 display-role for older browsers */
article, aside, details, figcaption, figure,
footer, header, hgroup, menu, nav, section {
    display: block;
}
body {
    line-height: 1;
}
ol, ul {
    list-style: none;
}
blockquote, q {
    quotes: none;
}
blockquote:before, blockquote:after,
q:before, q:after {
    content: '';
    content: none;
}
table {
    border-collapse: collapse;
    border-spacing: 0;
}

This set of rules standardizes elements and eliminates inconsistencies across different web browsers.

If you continue to encounter errors, consider including the following adjustment below the reset:

div{
width: 0px;
height: 0px;
}
