如何在选择时使 HTML 单选按钮变为粗体?
在 HTML 中，我有以下单选按钮选项
In HTML, I have the following radio button choices
o 选择 1
o 选择 2
o 选择 3
o Choice 1
o Choice 2
o Choice 3
我想要做的是，当有人从上方选择一个单选按钮时，与所选单选按钮对应的文本变为粗体.
What I would like to do is when someone SELECTs a radio button from above, that the text corresponding to that radio button selected becomes bold.
因此，例如 - 如果该人选择选择 2"，则单选按钮选择现在看起来像:
So, for example - if the person selects "Choice 2", the radio button selection would now look like:
o 选择 1
o 选择 2
o 选择 3
o Choice 1
o Choice 2
o Choice 3
我该怎么做?我假设必须使用 JavaScript 或 CSS.
How do I do this? I assume either JavaScript or CSS has to be used.

更新:如果不使用 jQuery，你将如何实现nickf"解决方案?
推荐答案
你可以纯粹用 CSS 来做到这一点，但你需要将每个输入的文本包装在 span 或其他标签中:
You can do this purely with CSS, but you need to wrap the text of each input in a span or other tag:
<input type="radio" name="group1" value="Milk"><span>Milk</span><br>
然后只使用兄弟选择器:
Then just use the sibling selector:
input[type="radio"]:checked+span { font-weight: bold; }
