How to increase the line space in CSS

[Sylver]

Hi, I am converting txt files to epub for reading on the nook using Calibre. As I need to use my own fonts for the Chinese, I put the following script into the .css box to have it use my own fonts that I put on the sd card. Everything works well except the space between the lines is to small (literally each line is followed immediately by another line without any space), I changed the font size in the nook and the space between lines does not change at all. I am sure it's a simple edit on the script that follows, but have no idea how to set it, can someone help? many thanks.

@font-face {
font-family: "MSYaHei";
font-weight: normal;
font-style: normal;
src: url(res:///sdcard/font/msyh.ttf);
}
@font-face {
font-family: "MSYaHei";
font-weight: bold;
font-style: normal;
src: url(res:///sdcard/font/msyhbd.ttf);
}

body { font-family: "MSYaHei", serif;}

I know nothing about Chinese fonts but you could try adding a line-height to the body element e.g

body { font-family: "MSYaHei", serif; line-height:200%}

...then play about with the 200% until it suits.

Thanks, I actually just noticed on the on Look & Feel tab, you can specify line height by points which worked for me.

After unzip the compiled file and checked the css, it says "line-height: 1.5em;", I used base font size of 16 and put in the line-height as 24 which is exactly 1.5 times of the base font. Not sure what "em" stands for, but it does make sense. Thanks again, Jackie_w.
