Below is my code which is working fine when the window is in full size. But on window re size, the logo and the header does not appear properly.[Here is my code](https://jsfiddle.net/c7germbj/)
Do I need to change the CSS or can the same using bootstrap. I tried changing the values given in pixel to percentag. Still it didn't work.

```
<div class='header'>
    <img style='position:absolute;margin: 12px 10px;'  src='https://business.microsoft.com/-/media/mssc/footericons/xbox.ashx?h=52&la=en&w=52&hash=94B5BB82970A4CF66DBE9F0D78B7E10EBD2D9A5B'/>
    <h1 class="heading">My page</h1>
</div>

```
