Body top gap; should I use margin or padding?

问题

So, I'm working on a website with a fixed header (which is used to navigate).
I use padding-top on body to lower the content to fit with the header.

This is how it looks like right now:

body
{
    background-color: red; 
    padding-top: 50px;
}
.header {
    background-color: yellow;
    position: fixed;
    width: 100%;
    height: 50px;
    top: 0;
    left: 0;
}

<div class="header">
    Header
</div>

My question is: What would be better to use in this situation? margin-top or padding-top?

回答1:

There's no actual better way to do it. It's just to you. Maybe one will be slightly faster to render then another but nothing that someone could notice.

As a tip anyway is to make the header positioned as fixed so it scrolls down with the user.
