允许网页宽度自动调整在 head 标签里加入 viewport 元标签, viewport 是网页默认宽度和高度 //网页宽=屏幕宽,原始缩放比0.5 　　<meta name="viewport" content="width=device-width, initial-scale=0.5" /> 不要固定宽度,字体也是　　使用 width : xx % ;或 width : auto ; 在写CSS的时候，需要注意： -1. body选择器中声明Font-size=62.5%； -2. 将你的原来的px数值除以10，然后换上em作为单位； -3. 重新计算那些被放大的字体的em数值。避免字体大小的重复声明。也就是避免1.2 * 1.2= 1.44的现象。比如说你在#content中声明了字体大小为1.2em，那么在声明p的字体大小时就只能是1em，而不是1.2em, 因为此em非彼em，它因继承#content的字体高而变为了1em=12px。 em是相对长度单位。相对于当前对象内文本的字体尺寸。如当前对行内文本的字体尺寸未被人为设置，则相对于浏览器的默认字体尺寸。(引自CSS2.0手册) 任意浏览器的默认字体高都是16px。所有未经调整的浏览器都符合: 1em=16px。那么12px=0.75em,10px=0.625em。为了简化font-size的换算

I'm trying to do something that should be very simple but I've spent my day between failures and forums.. I would like to adjust my font in order to match my baseline. On indesign it's one click but in css it looks like the most difficult thing on earth.. Lets take a simple example with rational values. On this image I have a baseline every 20px. So for my <body> I do: <style> body {font-size:16px; line-height:20px;} </style> Everything works perfectly. My paragraph matchs the baseline. But when I'm scripting my <h> that doesn't match the baseline anymore.. what am I doing wrong? That should

I understand how to obtain the text from a specific div or span style from this question: How to find the most common span styles Now the difficulty is trying to find all the span styles with font sizes larger than the most common one? I suspect I should use regular expressions, but first I need to extract the specific most common font size? Also, how do you determine "larger than" when the condition is a string? This may help you:- from bs4 import BeautifulSoup import re usedFontSize = [] #list of all font number used #Find all the span contains style spans = soup.find_all('span',style=True)
