问题描述
我有必须从页面的绝对左上角开始的html内容.但是，HtmlConverter会自动在pdf页面的顶部和左侧添加0.5英寸的间隙.如何覆盖此默认边距?
I have html content that has to start at the absolute top left corner of the page. However, the HtmlConverter automatically adds a 0.5in gap from the top and left side of the pdf page. How do I override this default margin?
推荐答案
您可以使用@page通过CSS设置页面的页边距.以下声明将所有页边距设置为0，并在段落周围绘制边框以供视觉参考:
You can set the margins of a page through CSS using @page. The following declaration sets all the page-margins to 0, as well as draws a border around paragraphs for visual reference:
@page{
margin:0pt;
}
p{
border-left: solid 2pt blue;
border-top: solid 1pt blue;
border-bottom: solid 1pt blue;
}
使用以下内容作为输入:
Use the following as input:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>margin example</title>
<link href="margin.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div>
<p>This page should have the margins set at 0</p>
</div>
</body>
</html>
您将看到该段落的边框触及页面的左侧，但尚未触及页面的顶部.那是因为该段也有一些先天的空白作为阻碍.将此设置为0将达到目的:
And you'll see that the paragraph's border is touching the left side of the page, but not yet the top side. That's because the paragraph has some innate margin as a blockelement as well. Setting this to 0 will do the trick:
p{
border-left: solid 2pt blue;
border-top: solid 1pt blue;
border-bottom: solid 1pt blue;
margin-top: 0pt;
}
@page{
margin:0pt;
}
