parent page
#divmotto{
font-size:100%;
font-style:italic;
font-weight:bold;
float:center;
width:100%;
text-align:center;
background-color:#E4521E;
padding:0%;
clear:both;
color:#DCED8F;
margin:0%;
border:0%;
}
<div id="divmotto">my motto</div>
//page shows motto in centre of row across page
var usedLater = document.getElementById("divmotto").scrollHeight;
document.getElementById("divmotto").style.display = "none";
//then link to child page in iframe

child page
parent.document.getElementById("divmotto").style.display = "inline";
parent.document.getElementById("divmotto").style.visibility = "visible";
//motto shows text on left, width only sufficient for text, but font and colours okay.
//width:100%;text-align:center; properties seemingly ignored, all browsers.
How can I get width:100%; and text-align:center; correct ?
Thanks.
 
there is no such thing as float: center;

And you cannot centre an element that is 100% wide.

To horizontally center a block element in it's parent, the child has to have a width of less than 100% and it's left and right margins set to auto.

display: inline; makes a block element behave as an inline element would ie. it is only as wide as it's content plus left and right padding, so text-align center; has no visible effect.

Also, pages in iframes are not affected by the parent page's CSS since they complete pages they have their own structure and CSS to go with it.
