How to properly move a Bootstrap panel?

I have a problem where I want a panel from Bootstrap to be in a position like in the picture 1.

I have moved it here using some CSS:

.welcome_panel { display: inline-block; float: left; width: 340px; height: 100px; margin-top: -404px;  }

However, now I want this panel on another page, this CSS sends the panel off screen.

Any suggestions?
