放入div中的图片不变形的解决方法

由 与世无争的帅哥 提交于 2019-12-11 13:46:58
前言 在DIV CSS布局中对于图片排版时，如果使用CSS固定死图片大小（宽度 高度），如果图片相对于这个位置不是等比例大小，那么这张图片就会变形。以下是解决图片变形的方法。 方法 第一种 让图片和布局宽度高度成等比例，这样CSS设置死宽度和高度，图片也是等比例缩小，图片也不会变形。 <head> <meta charset="UTF-8"> <meta name="viewport" content="width=<device-width>, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> .imgcss{ width:400px; height: 400px; border:1px solid red; } .imgcss img{ width: 400px; height: 400px; } </style> </head> <body> <div class="imgcss"> <img src="./image/timg.jpg"> </div> </body> 图片原本的宽高都是800px,等比例缩小成400px后，图片不变形。如下图： 第二种 使用max-width:300px或max-height

iOS9 Safari viewport issues, meta not scaling properly?

由 半城伤御伤魂 提交于 2019-12-11 10:19:09
问题 I have a bizarre issue with a recent website deployment - the website is not scaling properly on any iOS9 Safari-mobile browser which appears to shrink the site. This does not appear to be a problem for any other device as far as I can see and I have tested it on Firefox (Android and Desktop), Chrome (Android and Desktop), Safari (Desktop), IE (Desktop). Does anyone know a fix for this? Many thanks [UPDATE] Following on from a discussion here this meta seems to do the job: <meta name=

Django permission inheritance problem and Meta

由 断了今生、忘了曾经 提交于 2019-12-11 05:31:42
问题 I understand Meta can be inherited if the superclass has abstract=True, but can't be inherited otherwise. Is this because Django somehow consumes and removes the Meta class from concrete classes? I'd like to do something as in the example below, so Derived can get the Meta properties from Base (in this case, to inherit permissions as part of django-guardian). Suggestions on how to achieve this would be appreciated. Ian class Base(Model): class Meta: permissions = (("foo", "Allowed to do foo")
