血红的双手。 提交于 2019-12-19 03:09:43
Flexbox是一个CSS3的盒子模型(box model),顾名思义它就是一个灵活的盒子(Flexible Box)。 Flexbox模型概念 第一步要来看Flexbox的盒子模型,根据W3C文章所描述,flex的盒子模型如下图所呈现,与一般的盒子模型不同的地方,在于Flexbox的盒子模型具有水平的起点与终点(main start、main end),垂直的起点与终点(cross start、cross end),水平轴与垂直轴(main axis、cross axis),然后元素具有水平尺寸与垂直尺寸(main size、cross size),这些都是相当重要的布局概念。 Flexbox属性介绍 再来我们先看看Flexbox有哪些属性: display flex-direction justify-content align-items align-self align-content flex-wrap order flex display display是我们熟知的CSS属性,对于Flexbox来说,多了有两种方式可以设定,预设为“flex”,其布局方式与block几乎类似,都会强迫换行,但设定display:flex的子元素却具备了更多弹性的设定,此外另外一种方式则是“inline-flex”,和inline-block也是几乎雷同,意义上都是一个display

CSS: Is a hidden object clickable?

孤街醉人 提交于 2019-12-17 15:54:24
问题 If the visibility property of the style of an HTML element is set to hidden , is it still clickable? When the display property is set to none , the element is not even part of the DOM tree, so that is not a problem. But I was wondering if a hidden element still responds to mouse events. 回答1: With display: none it is still part of the DOM. It just isn't rendered in the viewport. As for clicks on elements with visibility: hidden , the events are not fired. jsFiddle. $('div').click(function() {

JavaScript - add transition between display:none and display:block

问题 I am using JavaScript to toggle notification like below. How can I add transition between display: block and display: none; I don't want to add an external library like jQuery because I am only going to be using the toggle effect alone. var btn = document.querySelector('button'); btn.addEventListener('click', function(){ var hint = document.getElementById('hint'); if(hint.style.display == 'none'){ hint.style.display = 'block'; } else{ hint.style.display = 'none'; } }); div#hint{ background:

Best replacement for font tag in html

浪尽此生 提交于 2019-12-17 09:49:41
问题 Since the font tag in HTML is being deprecated in HTML5 (and I understand why) is there a clean solution for applying certain attributes and styles to only portions of a paragraph text? I'm using JavaScript to parse an XML file that relies on the fact that the font tag allows portions of wrapping text to be formatted using class-based CSS. I realize the "anchor" ( a ) tag could also be used for this purpose, but that way seems very backwards and unnatural. EDIT When I asked this question (a

display:none与visible:hidden的区别

display:none与visible:hidden的区别 display:none和visible:hidden都能把网页上某个元素隐藏起来,但两者有区别: display:none ---不为被隐藏的对象保留其物理空间,即该对象在页面上彻底消失,通俗来说就是看不见也摸不到。 visible:hidden--- 使对象在网页上不可见,但该对象在网页上所占的空间没有改变,通俗来说就是看不见但摸得到。 例子: <html> <head> <title>display:none和visible:hidden的区别</title> </head> <body > <span style="display:none; 隐藏区域</span><span style=" background-color:Green">显示区域</span><br /> <span style="visibility:hidden; 隐藏区域</span><span style="background-color:Green">显示区域</span> </body> </html> display:none和visible:hidden都能把网页上某个元素隐藏起来,但两者有区别: display:none ---不为被隐藏的对象保留其物理空间,即该对象在页面上彻底消失,通俗来说就是看不见也摸不到。

CSS3 Flex布局(伸缩布局盒模型)学习

CSS3 Flex布局(伸缩布局盒模型)学习 转自:http://www.xifengxx.com/web-front-end/1408.html CSS2定义了四种布局:块布局、行内布局、表格布局盒定位布局。 CSS3引入了一种新的布局模式——Flexbox布局,即伸缩布局盒(Flexible Box)模型,此布局对于设计比较复杂的页面非常有用,特别是“垂直居中”布局,非常容易实现。 Flexbox布局语法有三种: 旧版本:2009年版本,使用display:box或者display:inline-box; [目前仅Safari浏览器支持] 混合版本:2011年版本,使用display:flexbox或者display:inline-flexbox; [仅IE10支持] 最新版本:使用display:flex或者display:inline-flex. [目前的主流浏览器均支持,不过在Webkit内核浏览器需要使用前缀“-webkit-”] 对于Flex布局,最初是通过看绿叶学习网,学的是flexbox旧版本,感觉很简单;然后又看了大漠老师的《图解CSS3-核心技术与案例实战》,其中详细介绍了三种布局,但我理解的不深,有些迷糊。最后通过网上找到了阮一峰翻译的一篇文章,直观易懂,终于明晰了Flex布局。 关于Flexbox布局旧版本(display:box/inline-box

Show DataFrame as table in iPython Notebook

问题 I am using iPython notebook. When I do this: df I get a beautiful table with cells. However, if i do this: df1 df2 it doesn't print the first beautiful table. If I try this: print df1 print df2 It prints out the table in a different format that spills columns over and makes the output very tall. Is there a way to force it to print out the beautiful tables for both datasets? 回答1: You'll need to use the HTML() or display() functions from IPython's display module: from IPython.display import
