font-size

I can't change the fontsize in a direct.label (from the directlabels package) ggplot2 plot. See below for a reproducible example - there's no problem in rotating the labels 45 degrees, making them bold, serif, and 50% transparent (all the other arguments in the list at the end of the code below) - but I can't control the fontsize. (I don't really want them to be 25, this is just for testing....) Is there something I'm missing, or is this a bug? library(ggplot2) library(scales) library(directlabels) df <- data.frame(x = rnorm(26), y=rnorm(26), let=letters) p <- ggplot(df, aes(x, y, color=let))

What are the advantages & disadvantages of each? em , px , % and pt ? My current choice are percentages, the only reason is because I can globally change the font-size of all elements, just by modifying the font size on the root element (body) I would recommend EM — simply because I use Baseline CSS for my basic set up of forms, layout and most importantly type. Can't recommend it enough : http://baselinecss.com/ My original design training said em's where possible. I believe a main reason was that different browsers and devices have different resolutions, which is once again becoming a big

How do you adjust the font size of an Android WebView ? The following appears to have no effect: private void fontSizePlus() { fontSize = (fontSize < FONT_SIZE_MAX) ? fontSize + FONT_SIZE_INCREMENT : fontSize; this.changeFontSize(fontSize); } private void fontSizeMinus() { fontSize = (fontSize > FONT_SIZE_MIN) ? fontSize - FONT_SIZE_INCREMENT : fontSize; this.changeFontSize(fontSize); } private void changeFontSize(int value) { String js = "document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '" + value + "%';"; mWebView.loadUrl("javascript:(function() { " + js + " })()"); }

当我们使用多个img标签时就会遇到img自带间距的问题如下 解决这个问题很多种方法，下面来简单说一下 1.如果只想解决解决竖向的间距 只需用vertical-align这个属性就可以了 img{ vertical-align: top; } 或者给img标签的父元素加上line-height属性 div{ line-height: 0; } 如果图片很宽一个就占一行的画，比如移动端的长图，给图片加display:block;就可以了； 2.如果只想解决左右的间距问当然可以把四周的间距都取消，然后加margin或者padding，但在网上发行有朋友在img标签左右加上注释包裹，亲测有效果 <img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src="./temimage.jpg" alt=""><!-- --><img src=".

一、rem 和 vw 简介 1. rem rem 是相对长度单位，是指相对于根元素(即html元素)font-size(字号大小)的倍数。 浏览器支持： Caniuse 示例 若根元素 font-size 为 12px html { font-size: 12px; } h1 { font-size: 2rem; /* 2 × 12px = 24px */ } p { font-size: 1.5rem; /* 1.5 × 12px = 18px */ } div { width: 10rem; /* 10 × 12px = 120px */ } 若根元素 font-size 为 16px html { font-size: 16px; } h1 { font-size: 2rem; /* 2 × 16px = 32px */ } p { font-size: 1.5rem; /* 1.5 × 16px = 24px */ } div { width: 10rem; /* 10 × 16px = 160px */ } 2. vw vw 是相对长度单位，相对于浏览器窗口的宽度，浏览器窗口宽度被均分为100个单位的vw 浏览器支持： Caniuse Opera Mini不支持该属性 示例 当浏览器窗口宽度为320px时，1vw = 3.2px p { font-size: 5vw; /

rem ·rem单位：CSS3 新增的一个相对单位；相对于根元素html的font-size的值进行动态计算得到的，如font-size：14px，1rem = 14px。 例：根据当前屏幕宽度和设计稿宽度计算html-fontsize的值 设计稿宽度：640px，fontsize：14px，屏幕宽度是375px，则font-size = 375/640*14 即：375/600 = fontsize/14 如果html的fontsize的值改变了，之前设定的所有rem单位的值自动会跟着放大或者缩小；目前移动端响应式布局，推荐使用 rem。 注意：rem需要配合媒体查询才可实现响应式布局 em ·em单位:相对于父元素字体大小，默认情况下，1em = 16px 一般适用于响应式，但不推荐使用，计算比较繁琐。 vw/vh vw单位：viewpoint width 视窗宽度的百分比（1vw 代表视窗的宽度为 1%） vh单位：viewpoint height 视窗高度的百分比（1vh 代表视窗的高度为 1%） 一般适用于百分比布局。 响应式布局和自适应布局区别 1.自适应布局通过检测视口分辨率，来判断当前访问的设备是：pc端、平板、手机，从而请求服务层，返回不同的页面； 响应式布局通过检测视口分辨率，针对不同客户端，在客户端做代码处理，来展现不同的布局和内容。 2

My application has two views, a live mode and a preview mode. Both of these have windows which can be resized. They are the same html file. I am looking for a way to get the font-size to resize proportionally for both views when they are resized. I am using jQuery as my javascript framework. Is there a way of getting this to work in either CSS or jQuery? I know I am answering my own question, but the answer above was helpful but not enough to suffice as one. So this is how I ended up doing it. First I set up this function which calculates a suitable font size based on a given width. function
