<a> tag still has margin even after setting global margin and padding to 0-CodePudding

Just like the title, I want a box with size 320px*40px, with 4 smaller boxes, size 80px*40px, and with no margin or padding. I used * { margin: 0; padding: 0; }, but the margin is still there.

      line-height: 40px;
      text-align: center;
    }
    
    .box .minibox:hover {
      background-color: #edeef0;

I tried to add margin: 0; padding: 0; in the selector of the tag, but nothing happened.

Removed the width and the height, you have line-height. I could not and cannot see the issue using Chrome.

There is no margin or padding.

As you can see in the screenshot above, using dev tools on a .minibox class, the only thing affecting the look of the box is the width, height and also line-height. If you delete those properties then the box will be as wide and as high as the content inside of it.

The gap that I wanted to remove is the enter key I tapped before. The only thing I need to do is to put 4 hyperlinks in a line in my code.
