Homepage layout like demo

Hi

I want to create the same look like here in the demo about page (text on the left and image on the right). I know it’s built with the avia layout builder but just can figure out how. I am using the text box element but the text is sticking to the sides. Can’t figure out how the center align the text. Also, how to set the image like in the demo ? Like taking the full width and height.

Thanks.
