僅為元素重置/刪除CSS樣式我肯定這之前肯定有人提過/問過，但我一直在尋找一個沒有運氣的時代，我的術語一定是錯的！我隱約記得不久前看到的一條推文，其中指出有一個CSS規則可以刪除以前在樣式表中為特定元素設置的任何樣式。一個很好的使用示例可能是在移動第一的RWD站點中，其中許多用于小屏幕視圖中特定元素的樣式需要“重置”或刪除桌面視圖中的相同元素。一種CSS規則，可以實現以下功能：.element {
all: none;}示例用法：/* mobile first */.element {
margin: 0 10;
transform: translate3d(0, 0, 0);
z-index: 50;
display: block;
etc..
etc..}@media only screen and (min-width: 980px) {
.element {
all: none;
}}因此，我們可以快速移除或重新設置樣式，而不必聲明每個屬性。合乎道理?

/* basic modern patch */

這在原則上是正確的，但個人里程可能有所不同。例如，某些元素，如TextArea默認有一個邊框，應用此重置將使那些TextArea的邊框減少。
#reset-this-parent {
all: initial;
* {
all: unset;
}}
例如，如果作者指定了一個元素的All：Initial，它將阻止所有繼承并重置所有屬性，就好像在級聯的作者、用戶或用戶代理級別中沒有出現任何規則一樣。
這對于頁面中包含的“小部件”的根元素很有用，它不希望繼承外部頁面的樣式。但是，請注意，應用于該元素的任何“默認”樣式(例如，顯示：在塊元素上的UA樣式表中的塊)也會被吹走。
getElementsByTagName(“*”)將返回DOM中的所有元素。然后可以為集合中的每個元素設置樣式：
