Occasional jquery issue causing font to render incorrectly within iframe

Currently facing a bug that needs resolution, the issue has been identified but unsure of the solution.

An iFrame is loaded with content via jQuery like this:

var content = {{ json_encode($template) }};
$('#preview-iframe').contents().find('html').html(content);

View it in action: http://jsfiddle.net/9aV8v/

The form elements used are as follows:

            <select name="ccpick" data-obj=".custom-color-1" class="fontpick">
                <option value="Verdana">Verdana</option>
                <option value="NeutraText-Book">NeutraText-Book</option>
                <option value="Arial">Arial</option>
            </select>

Works correctly on: http://jsfiddle.net/K9pL7/

The challenge arises when setting default font, color, or size on some page elements.

Experience issues on Firefox where wrong fonts are returned:

Inconsistencies during Chrome updates leading to sudden fixes or breaks...

Encounters font-size selection problems too - could execution timing impact iframe loading?

JQuery snippet for reference:

...

CSS styling for main header:

.main-header {
    color: #000000;
    font-family: Arial;
    font-size: 1.5rem;
}

Seeking consistent results across browsers, similar to jsfiddle outcome.

Answer №1

One issue that arises is the inability to access CSS attributes from an Iframe when an external CSS file is being used.

However, relocating the CSS code directly into the document resolves this problem and allows it to function properly.
