I also wanted to keep it quite simple, so adding some styles without heavily cusomizing the page. I switched the page to the edit mode, Added a Content Editor Web Part, in which I added my CSS styles and texts.
<style>
#s4-workspace
{
background-image: url(‘LinkToYourImage/bkg2.jpg’);
background-size: cover;
}
#contentBox
{
margin: 0px;
}
#sideNavBox
{
display: none;
}
#contentRow
{
position: absolute;
bottom: 100px;
left:0px;
right: 0px;
}
</style>
<img src="LogoLink/logo.svg" style="width:100px; padding-top: 20px; display:block; margin: 0 auto;"/>
