问题 Upload Base64 Image Facebook Graph API i want to use this script that link is attached how i can use this in my wordpress post? i want to use this for fbcover photo site. 回答1: Take a look at this code I hacked together from various examples - you can use this to post a pure base64 string to the Facebook API - no server side processing. Here's a demo: http://rocky-plains-2911.herokuapp.com/ This javascript handles the converting of a HTML5 Canvas element to base64 and using the Facebook API to

Prevent fixed-position background-image: cover from resizing in mobile browsers upon address bar hide

Sorry for a lack of example on this one, but I figure it's easy enough to understand. I have a fixed background on my site, which is currently implemented like this: #background { position: fixed; top: 0; bottom: 0; left: 0; right: 0; background-color: #28305e; background-image: url(../images/background.jpg); background-size: cover; -moz-background-size: cover; background-position: center center; z-index: -10; } <div id="background"></div> This is great in all browsers so far except for mobile browsers where they hide the address bar upon scroll-down. When the address bar is hidden, the

The UIImage "image" is always empty ("null") though the cover is shown in the music app by apple. in iOS 7 it works fine, but with iOS 8 I get no cover.

background-size: cover not working in portrait on Android tablet

I'm using the background-size property for a full width and height background image but having trouble getting it to fully cover in Chrome on a Nexus7 tablet in portrait view. It only covers the width and not the height i.e. there is about 200px of white space below it. However when I view the site in desktop Chrome (or anything else) and on a vertical monitor to emulate portrait dimensions it covers no problem. Anyone have a solution?

I need to cover background in my site and I always see lags/slugs on mouse over or any other action. Do you have any idea how to fix this issue? I have a working example here (If I didnt update the code yet) : http://natgeo.geryit.com ul#posters li { background-position: center center; background-repeat: no-repeat; background-size: cover; float: left; height: 170px; position: relative; width: 25%; } It appears webkit doesn't cache the resized image and renders it every time, causing the lag. You're out of luck when it comes to background-size in chrome. I've seen people do it with Javascript /
