Some CSS properties not transferring when converting ePub to LRF

megacoupe · 10-15-2010, 03:08 AM

I have a beautiful ePub that I've painstakingly edited in Sigil to get the text to look just the way I want it... but when I convert that ePub to LRF (for use on my unupgraded PRS500), certain CSS properties just don't work.

The first property that I noticed doesn't work is:

Code:

text-align: center;

Being the inexperienced coder I am, I tried placing that property in <div> and <p> tags just to be sure. I also tried:

Code:

margin-left: auto;
margin-right: auto;

and

Code:

padding-left: auto;
padding-right: auto;

But the text wouldn't center. I even tried using the old school <center> tag.

Checking out some other parts of the LRF, I found that the following properties didn't work either:

Code:

text-align: right;
font-style: italic;

Though interestingly enough,

Code:

font-weight: bold;

worked just fine.

Now, I know that Calibre doesn't have LRF bugs fixed anymore and that I should have upgraded my PRS500 a long time ago, but I'm looking for other (constructive) answers. Could my CSS be wrong? Are these known issues with LRF that were never fixed? Are there any workarounds to getting these properties to work? Is there another epub2lrf converter that will convert the properties correctly?

(BTW, MOBI output was very similar to the ePub, so I'm pretty sure these bugs are isolated to the LRF format. Any tips to make the LRF output look closer to the ePub would be appreciated.)

I'm afraid LRF output is no longer maintained.

In general, the simpler the markup, the more likely it is to be correctly converted. Try converting the MOBI to LRF.

Kovid,

I just tried your suggestion: converting from ePub to MOBI, and then MOBI to LRF... and it seems to have worked! I didn't check each property, but the main ones seem to have converted properly.

Thank you for your help. I hope some other poor soul out there still using LRF might find this information useful.
