手动配置viewport-04

<meta name="viewport" content="...."> content值: 　　initial-scale=1.0 //初始缩放 假设 　　img --> width 360px 　　container --> width:960px --> 页面宽度 <meta name="viewport" content="initial-scale=1.0"> 　　那么设备垂直方向:360px 　　横着方向(就是手机打游戏的姿势):640px 页面宽度和可视区 很容易理解;页面宽度就是你的网页总体宽度,可视区就是viewport对应的属性 n个元素+2两个边框 ==>大框永远是页面的,第二个框永远是搞里面元素布局的 containner等于内容宽,外框960　　 第一种情况,就是你手机大小像素尺寸和页面一致那么不管内容多大顺序往下展示,占满屏 第二种你viewport尺寸比我页面内容要大肯定有边框,如果页面内容太窄(要居中两边留有空白太好做了)边框就会更大 第三种一行展示,就把视图变大即可 综上 name=viewport 而 content:width=页面宽度 //但这是固定的宽度 　content:device-width, initial-scale=1.0 //缩放比例 　　user-scalable //用户鼠标缩放 　　maximum-scale /

WPF中平铺的问题

由 末鹿安然 提交于 2019-12-05 04:32:51
这个问题可是困扰了好久！百度多次，才发现真的是天下文章一大抄。不过在那个抄的基础上又参考MSDN的基础知识，最后反正是试出来了！ 在国内中designer普及不够，也只能将就下photoshop了！因此就会产生很多的平铺问题！比较显著的就是1像素的平铺。下面这段代码可以解决这个问题。 <Canvas> <Canvas.Background> <VisualBrush TileMode="Tile" Viewport="0,0,2,28" ViewportUnits="Absolute"> <VisualBrush.Visual> <Image Source="图片.png"/> </VisualBrush.Visual> </VisualBrush> </Canvas.Background> </Canvas> 跟网上流传的不同之处在于。Viewport="0,0,2,28" 2，28代表你那个1像素图片（需要平铺的图片）的宽和高。后面这个是关键ViewportUnits="Absolute"> 要设置为Absolute哦！ 原文链接：https://blog.csdn.net/wuwo333/article/details/7393905 来源： https://www.cnblogs.com/331399815-Damon/p/11906104.html

R setting space between graphs on a multiplot

由 蹲街弑〆低调 提交于 2019-12-05 02:35:36
Following a previous R post Specifying ggplot2 panel width , I have been able to produce this plot: with this code. You can find the output of dput(datos) at http://ubuntuone.com/0Nlb97mOeDhSbFrbFKCeEG Now my question is how can I remove/reduce the white space between the graphs. I have found examples with ggExtra package, ggplot and facet, multiplots with options as plot.margin or panel.margin but couldn't find how to apply to my case. Thanks for your help. EDIT: I have just noticed that plots have not the same width. It is needed they have the same width so they can share x axis labels from

由 橙三吉。 提交于 2019-12-04 23:46:30
I have to check if an element in a list is within the viewport or not.For this i'm using the angular2 plugin angular-inviewport . What the plugin does is as soon as the card is withing the bottom of the window it return true.I want that the card should be in the center or at least somewhat near to the top of the window before i register the impression. For this i need the reference of the current element and compare it with the window height and Yoffset something like this (the last solution) . Below is a small snippet from my code and the callback i have. <li class="" *ngFor="let data of

WKWebView viewport shrink-to-fit not working on iOS 9.3

由 非 Y 不嫁゛ 提交于 2019-12-04 23:08:21
问题 In iOS 9.2, a WKWebView rendering HTML with fixed-width tables bigger than the device width could be told to shrink the content to fit by adding a viewport tag like this: <meta name="viewport" content="width=device-width, shrink-to-fit=YES"> This line caused the WKWebView to effectively zoom out the viewport so that the entire rendered page fit in the view frame without the need for scrollbars. For example, consider the following code, when run in viewDidLoad in a vanilla single view app:

Meta viewport ONLY for phones?

由 。_饼干妹妹 提交于 2019-12-04 21:00:56
问题 Is there a way to set the general responsive meta viewport () only for phones? We have a website that without that meta tag, zoomed out, looks fine on 7" and larger tablets, portrait and landscape, but it was just a bit too inconvenient on smaller devices. So to get it working how we wanted on phones, I had to use the <meta name="viewport"> tag, which then forced some media queries to fix things on the larger devices. Is there a way to set that meta tag on phones, and just device default

Webgl gl.viewport change

由 天大地大妈咪最大 提交于 2019-12-04 19:03:33
问题 I have a problem with canvas resizing and gl.viewport sync. Let's say that I start with both the canvas 300x300 canvas, and the initialization of gl.viewport at the same sizes ( gl.vieport(0, 0, 300, 300) ). After that, in browser's console I make my tests: I'm changing size of my canvas, using jquery, calling something like $("#scene").width(200).height(200) After this, i'm calling my resizeWindow function: function resizeWindow(width, height){ var ww = width === undefined? w.gl
