'property: 0' 或 'property: 0px' 在 CSS 中? [英] 'property: 0' or 'property: 0px' in CSS?

问题描述

我已经看到这个符号被大量使用，我想知道这两个符号之间有什么显着区别吗?

I've seen this notation used a lot, and I was wondering, is there is any notable difference between these two notations?

element#id
{
  property: 0;
}

和

element#id
{
  property: 0px;
}

我一直使用 property: 0px;，因为我觉得它看起来更简洁，但我不确定浏览器对 0px 的解释是否与 不同>0.

I use property: 0px; all the time, as I find it cleaner looking, but I'm not really sure if the browser interprets 0px differently than 0.

有谁知道哪个更好或更正确?

Does anyone know which one is better or correct?

推荐答案

虽然当值为 0 时单位是可选的，但我倾向于保留它，因为我可以用通过单击值并按向上/向下箭头键来打开 Chrome 的开发人员工具.没有单位，那真的不可能.

While the unit is optional when the value is 0, I tend to leave it in, as I can then tweak the values with Chrome's Developer Tools by clicking on the value and pressing the up/down arrow keys. Without a unit, that isn't really possible.

此外，CSS 缩小器无论如何都会从 0 值中剥离单位，所以最终它并不重要.

Also, CSS minifiers strip the units off of 0 values anyways, so it won't really matter in the end.
