两列定宽一侧自适应布局

　　这种布局与单列定宽单列自适应布局非常相似

思路一: float

【1】float + margin

　　缺点是IE6-浏览器的3px的bug，以及当自适应列中有元素清除浮动时，会使该元素不与左侧浮动元素同行，从而出现文字下沉现象

mPDF

mPDF는 UTF-8로 인코딩된 HTML에서 PDF 파일을 생성할 수 있는 PHP 라이브러리입니다. 원저자인 Ian Back은 자신의 웹 사이트에서 "즉시" PDF 파일을 출력하고 다양한 언어를 처리하기 위해 mPDF를 작성했습니다. HTML2FPDF와 같은 원본 스크립트보다 유니코드 글꼴을 사용할 때 속도가 느리고 더 큰 파일을 생성하지만 CSS 스타일 등을 지원하고 많은 개선 사항이 있습니다. RTL(아랍어, 히브리어), CJK(중국어, 일본어, 한국어)를 포함한 거의 모든 언어를 지원합니다. 중첩된 블록 수준 요소(예: P, DIV)를 지원합니다.
