阅读更多关于 Python matplotlib - how to move colorbar without resizing the heatmap?

问题 Hi so I have the following commands. To specify a subplot axes in the grid for the heatmap: ax4 = plt.subplot2grid((3, 4), (1, 3), colspan=1, rowspan=1) To create my heatmap in this axes: heatmap = ax4.pcolor(data, cmap=mycm, edgecolors = 'none', picker=True) To move the plot to the right in order to center it in the axes according to other subplots: box = ax4.get_position() ax4.set_position([box.x0*1.05, box.y0, box.width * 1.05, box.height]) To show the colorbar with no padding fig.colorbar

问题 I'm certain it's something super stupid, but I've been stuck for a while, now... So, I have images on a website, and I'd like them to move slightly on hover. So I have in the HTML: <a href="someaddress"><img class="thumb" src="somefile"/></a> And in the CSS: img.thumb { position:relative; top:0px; background:#333399; } img.thumb:hover { position:relative; top:5px; background:#00CCCC; } The backgrounds are there just to see whether something is happening. Actually, the background doesn't

Finding the offset client position of an element

阅读更多关于 Finding the offset client position of an element

问题 How to find the offset client position of an element using Javascript? (I assume the same code can be written in a BHO or Gecko/NPAPI). The problem I am facing is a way to find out the offset client position of the element. The e.srcElement.offsetX/Y does not give the correct value always (same goes for clientX/Y). In some cases we also need to consider the parent element scroll. How do we do this in general? Is there an easy way for this? 回答1: function getElementTop ( Elem ) { var elem; if (

如何实现优美的骨架屏

阅读更多关于如何实现优美的骨架屏

对于前端来说，最重要的莫过于用户体验了，这次我们聊一聊骨架屏 - Skeleton Screen 我们平常对于需要请求加载的内容，可能用的比较多的是loading动画，比如在内容区域放一个菊花图，当请求结束，并且render tree构造完成后，将菊花图移除，展示用户想看的内容。虽然这种方式没啥缺点，但是现在更多的网站开始使用骨架屏代替，因为它能带过来更好的用户体验。我们看几个例子： facebook jira linkedin slack 上图展示中，我们可以看到每个site从骨架图到真实内容的一个变化。如果你细心一点你会发现，不同site对于骨架图的block位置是不一致的： facebook将用户固定的头像，author，日期和一小部分文字作为骨架主体 jira则是标题和logo对应的很整齐 linkedin可以说完全没有对齐，而是使用一种更加的展示骨架布局 slack则是使用混合的loading方式，有骨架图也有旋转圆，不仅如此，slack并没有全部使用同一种灰色值，不同的block的颜色代表的该区域的字体颜色，这又是一种切换顺滑度的提升。不过他们都有一个共同点，就是采用简约的方式布局，我们可以以此为例，创造出独一无二的风格，来提高用户体验和加强品牌的风格，我想这会比一个loading logo带来更好的效果。上面简单的介绍了一下骨架图，接下来我们来说一下具体实现吧。

问题 I'm trying to implement an application which senses position from both GPS and the network provider and shows it on a Google Map. I succeeded in doing this, but I have a question: I get the provider in the onCreate() of my Activity (it extends LocationListener) locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Criteria criteria = new Criteria(); provider = locationManager.getBestProvider(criteria, false); location = locationManager.getLastKnownLocation(provider);

阅读更多关于 Can i use position: fixed vertically and and position: absolute horizontally?

问题 I have some text at the bottom of my page saying Built By Me in it. I have this in a fixed position 35px away from the bottom and left of the window so it moves as you scroll. What i actually want is to fix it vertically, so it moves as you scroll up and down and is always 35px away from the bottom of the window, but have it positioned 35px away from the left edge of the page (not screen) so it does not move when you scroll horizontally.I checked out this solution Position element fixed

（初级）css布局一、单列布局 1、基础知识块级元素 div p ul li dl dt 行级元素 img span input strong同一行显示、无换行 2、盒子模型盒子模型（边框border、外边距margin、内边距padding、内容content）盒子模型3维立体图：自上往下（边框、内容和内边距、背景图片、背景颜色、外边距）样式追求就近原则（行内样式>内部样式>外部样式） 3、自动居中 margin： 0px auto;实现自动居中（原理：外边距=（浏览器的宽度-外包含层的宽度）/2）（此时不能同时设置浮动和绝对定位）一般情况下：父层设置一宽度，子层设置100%就可以。（子层继承父层宽度） 4、css布局笔记 4-1 margin：auto #main { width: 600px; margin: 0 auto; } 设置块级元素的 width 可以阻止它从左到右撑满容器。然后你就可以设置左右外边距为 auto 来使其水平居中。元素会占据你所指定的宽度，然后剩余的宽度会一分为二成为左右外边距。唯一的问题是，当浏览器窗口比元素的宽度还要窄时，浏览器会显示一个水平滚动条来容纳页面。让我们再来改进下这个方案。 4-2 max-width 在这种情况下使用 max-width 替代 width 可以使浏览器更好地处理小窗口的情况

relative(相对定位) 对象不可层叠、不脱离文档流，参考自身静态位置通过top,bottom,left,right定位，并且可以通过z-index进行层次分级 absolute(绝对定位) 脱离文档流，通过top,bottom,left,right定位。选取其最近一个最有定位设置的父级对象进行绝对定位，如果对象的父级没有设置定位属性， absolute元素将以body坐标原点进行定位，可以通过z-index进行层次分级。 fixed（固定定位）这里所固定的参照对像是可视窗口而并非是body或是父级元素。可通过z-index进行层次分级。 static:无特殊定位,对象遵循正常文档流 Adiv是放在Bdiv上面的，并且屏幕小的时候各个文本框就单独占一行如下：这时需要用到position ：relatic实现， <div class="row searchRow" style=""> <div class="col-lg-4 margin_b20" style=""> <div class="floatLeft zhangdan-time-title ">开始时间：</div> <div class="zhangdan-time" style=""><input type="text" value="" class="form-control" id="appDate1" >
