问题 I am trying to do something that, I thought, was very simple. The header of a website I am building is a solid color that needs to span the entire width of the screen regardless of which browser it is veiwed in. What I have created so far works wonderful on desktops and laptops, but when I test it on a tablet or a mobile phone, the header does not span all the way to the right. The content inside of the header does span all the way however, which is really confusing to me. The only way I can

阅读更多关于 OAuth on REST API for mobile app

问题 Ι'm working on the backend of a mobile app, building a RESTful API using ASP.NET MVC 4 Web Api. The app will run on iOS and Android.

阅读更多关于 What's the best way to make a mobile friendly site?

问题 Speaking entirely in technology-free terms, what is the best way to make a mobile friendly site?

Android ignores maximum-scale when using fixed-width viewport meta-tag

阅读更多关于 Android ignores maximum-scale when using fixed-width viewport meta-tag

问题 I have a fixed-width web page (640 pixels wide). I would like this page to shrink to the width of a mobile device. However, if the device's native width is larger than 640 pixels, I do not want it stretched. Seems simple enough: <meta name="viewport" content="width=640, maximum-scale=1.0" /> This works as expected in iPad/iPhone. However, on an Android tablet (ex. in landscape mode), the content gets scaled up to fit the display. In other words, Android is simply ignoring maximum-scale=1 .
