Question

My HTML gets rearranged by browsers, causing a change in appearance

UPDATE: I have discovered that the issue lies with Internet Explorer which alters the class attribute of an HTML element from:

"<img class="blah".." to "<img class=blah..".

This inconsistency only occurs in IE for me. It does not affect other attributes such as src or id quotation marks, making it quite frustrating!

I am utilizing JQuery to enhance the visual appearance of a website. Within my main div (updatableDiv), I convert each editable HTML element (such as p, i, b, etc.) into a textarea. Users can make changes and upon submission, the textareas are converted back into their original format using JQuery.

The Issue at Hand: When attempting to retrieve the HTML content from the div with the id updatableDiv, the obtained HTML is slightly altered, resulting in a variation in the displayed output. For instance, if there is an image positioned directly above a white box without any vertical space between them, after updating the HTML, a gap appears vertically between the image and the white box.

Initial HTML code (example from IE):

<img class="pageHeading" src="linksHeading.png" width="90%" alt=""/><div class="pageContent">

Upon retrieving the HTML using $("#updatableDiv").html(), the HTML now appears like this:

<IMG class=pageHeading alt="" src="linksHeading.png" width="90%">
<DIV class=pageContent>

Resulting in the introduction of a vertical gap.

Therefore, my primary concern is how to preserve the formatting of the HTML to avoid such issues when updating and retrieving the HTML content using JQuery's $("#updatableDiv").html()?

Obtaining the innerHTML in certain versions of IE may not return the original HTML, but rather a modified version that is functionally the same. This altered HTML can have differences such as missing quote marks around attributes, reordering of attribute placement, and changes in the case of attribute names.

In essence, when retrieving innerHTML in IE, you can expect semantic equivalence to the original HTML, but not necessarily an exact match due to the way it regenerates the code from object attributes. It seems IE does not retain the initial HTML structure and instead generates it based on the attributes present. As there are multiple valid ways to define attributes, IE may output the HTML differently than how it was input originally.

To address this discrepancy, manual formatting of the generated HTML according to personal style preferences (adding quotes, arranging attributes in a specific order, adjusting case sensitivity, etc.) may be necessary.

If you observe this jsFiddle in IE7, you will notice alterations made by the browser for all three mentioned items.

An example in IE7 involves this specified HTML:

<div id="test" data-item="test" style="background-color: red; height: 40px; width: 100px;">

The resulting innerHTML differs in order, capitalization, and quotation usage:

<DIV style="BACKGROUND-COLOR: red; WIDTH: 100px; HEIGHT: 40px" id=test data-item="test"></DIV>

The issue with additional white space around images could potentially be caused by IE's default behavior of adding spacing. Modifying the image display to display: block, setting font-size: 0 on its container, or specifying a border can help mitigate this problem. Differences in interpretation of spaces between browsers, specifically older versions of IE, can lead to varying amounts of added line spacing.

Does the spacing of white-space in the source code affect your CSS classes during the transition?

By default, img elements are inline and align with the text baseline, leaving extra space below for letters like lowercase g. Block elements should align with the bottom of their containing block.

Have you tried adjusting the CSS settings:

img { display:block; }
// or maybe
img { vertical-align:bottom; }
