These features make it one of the best Epub readers Consider Sumatras to remove the boredom in your life while reading your favourite publications. The interface is minimalistic with topics arranged in a list. A wonderful application that gives a feel reading an old book which is soothing to look at. Other than ePUB format it also supports PDF, MOBI, CHM, XPS, DjVu, CBZ and CBR. The application is free, lightweight and portable PDF and Epub reader for Windows. I'm not sure how this works in a nested hierarchy.You might have heard of Sumatra if you are a Windows user and an Ebook lover. If you're always using Charis you probably need even less. In reality I probably only use a few of them to allow for the fact that some fonts are bigger than others. In case it helps I've started mine at 22 and finished at 45. The main thing with font-size in the Patcher is to make sure that the 24 values you pick increment in steps of 1, so you get fine control - no nasty jumps in all the wrong places like the unpatched fw. But when the publisher specifies a size and it's not a problem with the size, I usually leave it as is and its usually in em. I use mostly font sizes by name i.e., small, large, x-large, etc. I created that ePub so I can decide if I want to change the values of the font size slider in the patch. Have you really been editing your Sony epubs in hard-coded px units, like this test epub, all these years?

Whenever I change the font-size slider everything scales in proportion.

I do always add font-size:1em to whatever class corresponds to the tag, to normalise all the sizes lower down the hierarchy.only ever allow font-size css in classes which are supposed to be different from the normal body text, e.g.This results in the font-size slider properly controlling normal body text Also remove font-size from any other css class which shares that particular font-size value. if the main paragraph class contains a font-size, remove it.only specify font-size in em units (% should also work).I've found I get the best, most predictable results on all the readers I've used (Kobo, Sony, Pocketbook, Android apps) by:

8em instead of small for a font size and if I'm not mistaken, the Kobo will display these CSS styles in the same size as the body font. Also, I've seen a lot of CSS code that uses. A lot of CSS for small caps is specifying a font size of 7em or.
