Firefox徑向漸變問題

Question

嘗試將徑向漸變設置爲bg。問題是，所有其他瀏覽器顯示漸變，在Firefox不。怎麼了？產生這個網站http://www.colorzilla.com/gradient-editor/這個代碼（與IE9支持）

Answer 1

你需要補充一點：

html { 
    height: 100%; 
} 

因爲內body所有的元素都絕對定位，body沒有高度。

您已經添加到height: 100%body，但html也沒有height，所以height: 100%上body什麼也沒做。

將height: 100%添加到html使其與視口一樣高，然後height: 100%對body有效。
