我遇到的问题是，每当我尝试通过CSS2PDF创建PDF时，只要我想要添加的div具有一定长度并且CSS2PDF将返回空白PDF，它就可以正常工作。
因为它一直有效，直到我达到这一点，这不是包含文件的问题。
这是我用来在按钮的点击监听器中使用CSS2PDF的js代码：
return xepOnline.Formatter.Format('main',{embedLocalImages: 'true'});
这是我要添加到PDF的html：
<div class="col-lg-12 col-md-12 col-sm-12 col-xs-12" id="main" style="margin-top: 20px;">
<div class="entry" data-entry="5">
<h2>This is the title of the example-report</h2>
<h3>Subtitle, decent, but can also be <b>bold</b></h3>
<div class="wysiwyg-text-align-justify">This is a block of text, copied to represent a longer text.

一旦删除1行，它就会再次起作用。由于某种原因，它也不会自动启动新页面。
修改： tl; dr ：当内容达到一定大小时，CSS2PDF会给出空白页，在达到该大小之前，它会起作用。也没有自动分页符。
答案 0 :(得分：0)
可能是因为解析后的CSS中的bootstrap风格的自反布局（col- *）映射到了float。 CSS2PDF基本上将带有已解析CSS的HTML转换为XSL FO并对其进行格式化。在XSL FO（以及任何面向页面的语言）中，“float”不能大于页面。
尝试在没有class =“col-lg-12 col-md-12 col-sm-12 col-xs-12”的情况下进行格式化。
如果您尝试使用col-md-4为每列格式化三列中的页面，则会遇到同样的问题。这些将并排解析为三个浮点数，如果它们大于页面，则无法控制它们的行为，这会破坏格式化。甚至浏览器也很难尝试“打印”它。
