How can I position this block at top of page, but horizontally centered?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I am trying to use CSS+HTML to position a purple block at the top of the viewport. I want the purple block to be horizontally centered and appear on top of anything else. The way my code is organized, other elements (a green button) must appear above the purple block in my HTML file.



I'm using the HTML below. Properly positions the block at the top of the page and on top of other elements. But it is not horizontally centered. How can I make it horizontally centered using CSS?



Plunker here.



enter image description here



<!DOCTYPE html>
<html>
<head>
<style>
.pretty-button {
color: white;
background-color: rgba(17, 175, 29, 0.64);
border-radius: 0.6em;
border: 0.2em solid #73AD21;
padding: 0.5em;
}

.top-block {
position: absolute;
top: 0px;
height: 30px;
width: 60%;
margin: auto;
background-color: purple;
z-index: +1;
}
</style>
</head>
<body>
<button class="pretty-button">Button A</button>
<div id="div1">
<div id="div2">
<div id="div3" class="top-block">

            Just add this: transform: translateX(35%); and z-index: 999 to your .top-block class
