css - 如何更改语义 UI 图标的颜色？

Question

我可以用代码制作竖起大拇指的图标

<i class="thumbs up icon large"></i>

但是我怎样才能把颜色从黑色变成灰色呢？我这样做是为了 chrome 扩展，我在 manifest.js 中以这种方式添加了 CSS。 :

"content_scripts": [
    {
        "matches": ["http://*/*", "https://*/*"],

        "css": [ "tab/layouts/style.css", "app/lib/semantic.min.css" ],
        "js": [ "common/owconstants.js", "common/OWprotocol.js", "3rdparty/jquery-1.10.2.min.js", "3rdparty/jquery.mCustomScrollbar.concat.min.js", "3rdparty/jquery-ui-1.10.3.custom.min.js", "common/common.js", "tab/sidebars.js", "tab/communication.js", "tab/syncobject.js", "tab/popup.js", "tab/authorization.js", "tab/userinfo.js", "tab/annotation.js", "tab/usercard.js", "tab/userlist.js", "tab/notifications.js", "tab/friendlist.js", "tab/injection.js", "tab/drops.js", "tab/chat.js", "tab/tracking.js", "tab/keywords.js", "tab/tabscript.js", "app/lib/semantic.min.js"]
    }
],
