問題：
I've always used single quotes when writing my HTML by hand.在手動編寫 HTML 時，我總是使用單引號。 I work with a lot of rendered HTML which always uses double quotes.我使用了很多渲染的 HTML，它們總是使用雙引號。 This allows me to determine if the HTML was written by hand or generated.這使我能夠確定 HTML 是手工編寫還是生成的。 Is this a good idea?這是一個好主意嗎？
What is the difference between the two?兩者有什麼區別？ I know they both work and are supported by all modern browsers but is there a real difference where one is actually better than the other in different situations?我知道它們都可以工作並且受到所有現代瀏覽器的支持，但是在不同情況下一個實際上比另一個更好的真正區別是否存在？
