Remove extra padding from any grafana panel

Hi

I am currently trying to use Html panel. But i see unwanted padding/space at the bottom of the panel. How can i get rid of this.

If I try to size it manually I am loosing some of the text from the html panel.

<div style="width:100%;background:black;float:left;text-align:center;border: 0px solid black;line-height:0.5;">
                           <u><h2> Ent </h2></u>
                           <h3>BuildNumber = 12070</h3>
