Editor Limitations editor-limitations
The editor in the touch-enabled UI makes use of overlays to interact with content confined in an iframe. This interaction creates some limitations in both usage of the editor and also for developers. This page summarizes these limitations and provides solutions or work-arounds where possible.
Functional Limitations functional-limitations
An author may encounter the following functional limitations when using the editor to author pages.
Links Not Active links-not-active
When editing a page, links are not active.
- Switch to Preview mode to navigate using the links in your content.
Structure Pages structure-pages
Pages can not be named structure. Pages that are named structure will not be editable in the page editor.
CSS Limitations css-limitations
A developer may encounter the following limitations with the editor’s interactions with CSS.
Absolutely Positioned Elements absolutely-positioned-elements
Absolutely positioned elements can cause issues in the position of their overlay.
- If this happens, make sure that the dimensions of the absolutely positioned element are correct because the editor will create an overlay with the exact same dimensions.
vh Units vh-units
vh units are not supported because the iframe height must be automatically adjusted by AEM.
Fixed Background Images fixed-background-images
Fixed background images may not be displayed as fixed when scrolling due to the fact that it is embeded within an iframe.
- Selecting View Page as Published in the header bar actions displays the page properly.
100% Height height
100% height is not supported on a page’s body element.
- A work-around is possible in order to implement a fullscreen body by “stretching” the body element as follows:
body {
position: absolute;
top: 0;
bottom: 0;
right: 0;
left: 0;
}
Margin Collapsing margin-collapsing
Margin collapsing problems can be seen if the first child element of the body element has a margin.
- The solution is to add a clearfix at the body element level such as follows:
body:before, body:after{
content: ' ';
display: table;
}
