My first time installation of MODx showed a momentary flash of unstyled page content, and I came accross some information that may be helpful to others.
What is a FOUC?
Some pages that use the CSS @import rule experience a curious display quirk in the Windows version of MS Internet Explorer: a momentary flash of unstyled page content.
Code that is susceptible to FOUC.
<head>
<title>My Page</title>
<style type="text/css" media="screen">@import "style.css";</style>
</head>
The solution is to link to another stylesheet as follows - and it works even if the style sheet doesn’t actually exist !
<head>
<title>My Page</title>
<!-- following line needed to avoid Flash of Unstyled Content (FOUC) -->
<link rel="stylesheet" type="text/css" media="print" href="print.css">
<style type="text/css" media="screen">@import "style.css";</style>
</head>
