用 CSS 於連結後面加 icon (與副檔名相關小圖)

通常連結是 <a href ...>, 但是都沒法一眼看出, 到底是一般連結還是某種類型的檔案(除非滑鼠移到連結上, 看檔名), 拜讀兩篇文章, 用 CSS 去判斷副檔名或 class name 來給他小圖.

目前我也在副檔名是 pdf 的加上小圖, 其它的以後有空再來改~ :p

以下參考自兩位 CSS 大師的文章:

使用 CSS 於連結後面加入 icon 的方法如下:(此為我的範例)

a[href $='.pdf'] {
    padding-right: 18px;background: transparent url(/images/icon_pdf.gif) no-repeat center right;
}
a[href $='.doc'] {
    padding-right: 18px;background: transparent url(/images/icon_doc.gif) no-repeat center right;
}
a[href $='.xls'] {
    padding-right: 18px;background: transparent url(/images/icon_xls.gif) no-repeat center right;
}
a[href ^="mailto:"] {
    padding-right: 20px;background: transparent url(/images/icon_mail.gif) no-repeat center right;
}
a[class ="popup"] {
    padding-right: 18px;background: transparent url(/images/icon_popup.gif) no-repeat center right;
}
a[class ~="popup"] {
    padding-right: 18px;background: transparent url(/images/icon_popup.gif) no-repeat center right;
}
a[class ="external"] {
    padding-right: 18px;background: transparent url(/images/icon_external.gif) no-repeat center right;
}

a 後面能夠有以下幾種判斷法:

[foo] -- Has an attribute named "foo"
[foo="bar"] -- Has an attribute named "foo" with a value of "bar" ("bar")
[foo~="bar"] -- Value has the word "bar" in it somewhere ("blue bar stools")
[foo^="bar"] -- Value begins with "bar" ("barstool")
[foo$="bar"] -- Value ends with "bar" ("I was at the bar")
[foo*="bar"] -- Value has bar somewhere ("I was looking for barstools")

記得加的時後, icon 要準備好 :)

感謝 Haoming 提供他改寫的版本(可連到他的網站下載), 超方便.

我又基於他的版本再改寫一下, 主要是針對外部連結我再秀小圖(我外部連結通常都會有 target="blank", 所以改寫如下:

#content a[href $='.pdf'] {
    padding-right: 18px;background: transparent url(http://farm1.static.flickr.com/137/362353384_27b2da60cf_m.jpg) no-repeat center right;
}
#content a[href $='.doc'] {
    padding-right: 18px;background: transparent url(http://farm1.static.flickr.com/129/362353383_86d1c5ae90_m.jpg) no-repeat center right;
}
#content a[href $='.xls'] {
    padding-right: 18px;background: transparent url(http://farm1.static.flickr.com/150/362353380_d48d22e8f8_m.jpg) no-repeat center right;
}
#content a[href ^="mailto:"] {
    padding-right: 20px;background: transparent url(http://farm1.static.flickr.com/157/362353387_177cbdea21_m.jpg) no-repeat center right;
}
#content a[target ="_blank"] {
    padding-right: 18px;background: transparent url(http://farm1.static.flickr.com/128/362353389_fe347a775c_m.jpg) no-repeat center right;
}
