DetectingCSSLoad
sIFR can try to detect if the relevant CSS for the document has loaded. Using this check will speed up replacements in Safari and Opera – without it, the elements will be replaced on page load.
You can switch on the CSS load detection by setting sIFR.useStyleCheck = true; before calling sIFR.activate(). Please note that this is a bit of a hack, sIFR will temporarily insert a dummy element into the page, and test for a specific style attribute. For the CSS detection to work, you must place the following CSS code in the main stylesheet which also contains the .sIFR-active code:
.sIFR-dummy {
width: 0px;
height: 0px;
margin-left: 42px !important;
z-index: 0;
}
You'll have to make sure that the dummy element, which is a div, does not have a different margin-left due to other styles.
Without the above CSS, the elements will be replaced on page load in all browsers.
