Webpage starts zoomed in on mobile devices

问题 I'm using this code on my webpage <meta name="viewport" content="width=1000, initial-scale=1.0, maximum-scale=1.0"> I would think the initial scale would make sure the webpage was zoomed out, but it doesn't. Any ideas? I've tried this: <meta name="viewport" content="width=device-width, initial-scale=1.0"/> But, I need the width to be set to 1000px or it doesn't look correct. Answer: <meta name="viewport" content="width=1000; user-scalable=0;" /> 回答1: initial-scale=1.0 tells the browser to set

问题 I'm trying to figure out how to leverage the mobile viewport meta tag to automatically zoom the contents of a HTML page to fit into a web view. Constraints: The HTML may or may not have fixed size elements (ex img has a fixed width of 640). In other words I don't want to force the content to be fluid and use %'s. I do not know the size of the webview, I just know its aspect ratio For example, if I have a single image (640x100px) I want the image to zoom out if the webview is 300x250 (scale

0074 二倍图：物理像素&物理像素比、背景缩放background-size

由 假如想象 提交于 2019-12-26 15:37:57
3.1物理像素&物理像素比 物理像素点指的是屏幕显示的最小颗粒，是物理真实存在的。这是厂商在出厂时就设置好了，比如苹果6 是 750* 1334。 我们开发时候的1px 不是一定等于1个物理像素的。 一个px的能显示的物理像素点的个数，称为 物理像素比 或 屏幕像素比 。 如果把1张100*100的图片放到手机里面会按照物理像素比给我们缩放。 lRetina（视网膜屏幕）是一种显示技术，可以将把更多的物理像素点压缩至一块屏幕里，从而达到更高的分辨率，并提高屏幕显示的细腻程度。 对于一张 50px * 50px 的图片,在手机或 Retina 屏中打开，按照刚才的物理像素比会放大倍数，这样会造成图片模糊。 在标准的viewport设置中，使用倍图来提高图片质量，解决在高清设备中的模糊问题。 通常使用二倍图， 因为iPhone 6 的影响背景图片 注意缩放问题。 ​ /* 1. 物理像素 就是我们说的分辨率 iPhone8的物理像素是 750 */ ​ /* 2. 在 iPhone8里面， 1px 开发像素 = 2个物理像素 */ demo：二倍图做法 <!DOCTYPE html> < html lang = " en " > < head > < meta charset = " UTF-8 " > < meta name = " viewport " content = "

响应式设计的点点

移动web已经是大势所趋，所占份额迅猛增加。如果没有足够时间和精力做一套完全全新的移动端程序，那么，响应式设计也许是个不错的选择。不过，如果有条件并且需要移动端网页，移动端的很多优势还是不可替代的，比如定位功能。 响应式设计，使得可以使用同一网站在智能手机、电脑及其他设备上完美显示。它可以根据用户的屏幕尺寸，合理的为现在的和将来的设备提供好的浏览体验。 viewport viewport指的是浏览器窗口内的内容区域，即网页实际显示的区域，而屏幕尺寸是指设备的物理显示区域。可以阻止浏览器自动调整页面大小： <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"> 不过一般不会阻止用户手动缩放页面大小。 media-query media query可以为特定的输出设备定制显示效果。已经得到了很多浏览器的大力支持。在不支持的浏览器IE6-8中，也可使用respond.js这个polyfill. 一些例子： <link rel="stylesheet" media="screen and (max-width:600px)" href="small.css" type="text/css" />

问题 after reading a lot about browser viewport width issues, I concluded to make a trial to see that if I understood the concept. I used javascript below: This script prints "Your viewport width is WidthxHeight" Element 1: At a 1920 x 1080 resolution, HP x2301 screen without any scroll bar: JS printed: Your viewport width is 1920x955 Element 2: At a 1920 x 1080 resolution, HP x2301 screen with scroll bar (I increased the height of page with lots of lorem Ipsum string paragraphs): JS printed: Your
