問題描述
這是我不理解的 wordpress 樣式表中的一些內(nèi)容:
Here is something in a wordpress stylesheet that I don't understand:
blockquote cite,
blockquote em,
blockquote i {
font-style: normal;
}
blockquote 和 cite 之間的空格有什么作用?我知道如果它們用逗號分隔，那么 blockquote 和 cite 都會有 "font-style: normal;"現(xiàn)在它們用空格分隔，這是否意味著如果將塊引用標(biāo)簽嵌入到引用標(biāo)簽中，它將得到font-style: normal;"?
what does the space between blockquote and cite do? I understand if they are separated by a comma, then both blockquote and cite will have "font-style: normal;" now they are separated by space, does this mean if a blockquote tag is embedded into a cite tag it will get "font-style: normal;"?
謝謝.
推薦答案
空間被稱為 后代組合器.blockquote cite 選擇 blockquote 元素內(nèi)的任何 cite 元素.blockquote em 和 blockquote i 也是如此.
The space is known as the descendant combinator. blockquote cite selects any cite element within a blockquote element. Likewise for blockquote em and blockquote i.
換句話說，這不是如果將塊引用標(biāo)簽嵌入到引用標(biāo)簽中"，而是相反(此外，您不能將 blockquotes 放在 cites 放在首位).
In other words, it's not "if a blockquote tag is embedded into a cite tag", it's the other way around (besides, you can't place blockquotes in cites in the first place).
如您所見，逗號將選擇器序列分組到同一規(guī)則中.
As you note, commas group selector sequences into the same rule.
