line-height:属性值;
Possible attribute values
normal Default. Set reasonable line spacing.
number Set a number that will be multiplied by the current font size to set the line spacing.
length sets fixed line spacing.
% Percent line spacing based on the current font size.

<!DOCTYPE html>

<head>
<meta charset="utf-8">
<style>
p.small1 {line-height:70%;}
