overset

W3C Working Draft

Summary

Indicates whether a flow's content exceeds available space within a region chain, or if no available chain in which to flow content exists.




Property of apis/css-regions/NamedFlow

Syntax

Note: This property is read-only.

var exceedsRegions = flow.overset;

Return Value

Returns an object of type Boolean.

Indicates whether a flow's content exceeds available space within a region chain. Also indicates when no chain is available in which to flow content.


Compatibility

There is no data available for topic "webapi", feature "overset". If you think that there should be data available, consider opening an issue.

Examples

JavaScript

// adds a region element to a prescribed container
// if there aren't already enough to display all content
function appendRegion(flowName) {
    var flow = document.getNamedFlows().namedItem(flowName);
    var layout = document.querySelector('#layout_wrapper');
    var region;

    // need to add more regions?
    if (! flow.overset) return(false);

    // assumes CSS such as:
    //   #layout_wrapper > div { flow-from: mainFlow}
    region = document.createElement('div');
    layout.appendChild(region);

    return(true); // perhaps for use in	while loop
}

appendRegion('mainFlow');

Notes

Not to be confused with regionOverset, which indicates the overset state of individual regions. Only the final region in a chain can be overset.
