其实我用这个标签,主要是给分享到 twitter 的时候能够让 twitter 自动抓取时生成的 card 带有缩略图。
bookmarklet 也一并分享一下吧:
```javascript
javascript:(function(){var D=640,A=480,C=screen.height,B=screen.width,H=Math.round((B/2)-(D/2)),G=0,F=document,url,text; if(C>A){G=Math.round((C/2)-(A/2))}; url=encodeURIComponent(window.location); text=encodeURIComponent(window.getSelection?window.getSelection().toString():(document.selection?document.selection.createRange().text:'')); if(text==''){ window.alert('Please, select text on the page first');}else{ window.open('http://twitter.com/share?url='+url+'&text='+text,'','left='+H+',top='+G+',width='+D+',height='+A+',personalbar=0,toolbar=0,scrollbars=1,resizable=1');}}());
