英文:
Can you use an ID or class of a HTML element as an identifier for CSS?
问题
我正在学习更多编程语言的路上。自从HTML 4.01以来，我从未练习过HTML。但这更多是与CSS有关的事情。
我以为，因为我看到H1和P1是有效的，所以我尝试了button1。感到愚蠢，然后考虑使用ID作为标识符。我想要在左边制作一个按钮，另一个在右边。
在w3schools和其他网站上找不到任何信息。感觉我在表达一切的时候都错了。
英文:
I'm on my road trip roundabout of learning more coding languages. Never practiced HTML since HTML 4.01. But this is more of a CSS thing.
I was expecting, since I see H1 and P1 being a thing, so I try button1. Feel stupid, then think about using an ID as an identifier. I want to make one button on the left and the other on the right side.
I can't find anything on w3schools, and other sites. I feel like I'm wording everything wrong.

是的，可以。确保类名或ID已设置为您的元素：
<div class="my-div-class" id="my-div-id"></div>
然后在样式表中，您可以使用“选择器”来访问它们。类使用前置的.选择，而ID使用前置的#选择：
.my-div-class {
/* 一些样式... */
}
#my-div-id {
/* 一些样式... */
}
您可以在W3Schools这里查看所有的CSS选择器：https://www.w3schools.com/cssref/css_selectors.php
或者在MDN这里查看：https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors
英文:
Yes, you can. Ensure the class name or ID are set to your elements:
<div class="my-div-class" id="my-div-id"></div>
And then in your stylesheet, you can access these using 'selectors'. Classes are selected with a preceding ., and IDs with a preceding #:
.my-div-class {
/* Some styles... */
}
#my-div-id {
/* Some styles... */
}
You can see all CSS selectors here from W3Schools: https://www.w3schools.com/cssref/css_selectors.php
Or here from MDN: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors
