Question about ADE

crutledge · 04-14-2013, 01:14 PM

I have the following definition in the CSS:

Code:

.centerbox{
width:50%;
padding:10px
font-size : 90%;
margin-left:auto;
margin-right:auto;
margin-bottom:1em;
}

It displays properly centered on the page in Sigi, Calibre ePub reader, Kindle, and Sony but in ADE it is left justified. See attached images.

Is this a problem with ADE or have I missed something?

Thanks

Where is the alignment in that definition?

I mean, for alignment I think you need:

Code:

text-alignment: center;

I don't wish to center the text - only the block.

Faulty css ? Missing ; on

Code:

padding:10px

That's the part that's centering the block, and the part that doesn't work in ADE, because, according to the ePub spec:

"Reading Systems may set the value of any margin property whose specified value is auto to 0."

and it seems ADE just chooses to do that, there's not much we can do.

But, since you are using a relative width, anyway (width:50%), you can get the desired effect with:

Code:

margin-left:25%;
margin-right:25%;

(actually, I'm surprised it works in the Sony, which version is it?)

Please note there is a semicolon missing in the 3rd line of your code. ADE will ignore the rest of the stylesheet if it finds any tiny error or mistype.

That did it. Thanks very much.

You can also use this:

.center{text-align: center;}
.centerbox{width:50%; padding:10px font-size : 90%; margin-bottom:1em; }

<div class="center"><p class="centerbox">This text will be left-aligned, but centered in a block.</p></div>
