Prevent <button> from shifting during click

问题:

When you have a simple element in a page and click it (hold down the mouse during click to see the effect) in IE8/9 then the button shifts a little down and to the right.

I'm assuming this is part of the default IE style. Is there anyway to prevent this behavior?

You can stop the text moving in IE button:

button:active span, button:focus span {
    position:relative;
    top: 0;
    left: 0;
}

<button><span>no move</span></button>

Put your text on a <span> and position:relative in it, it'll fix.

button span{
    position: relative;
}

No need for top and left definition.

You can apply some styles to the button. button{ margin: 0px; padding: 0px;}

If you don't mind using JavaScript, apparently this does the trick:

$(document).on('mousedown', 'button, input[type="button"], input[type="submit"]', function(e) {
  e.preventDefault();
});
