> it's the sameIt doesn't look the same to me. The logo in your second screenshot is centered, but in the first screenshot it was lined up with the "MOODLE ESHTE" logo.
Personally speaking, I don't think you should center the image. Leave it left aligned.
One trick you could try to make the logo left-aligned but appear to occupy the entire screen width on varying screen sizes is to put the image in a <div> which has a certain background color. The <div> should stretch to the right hand side of the screen. Now, remove the red border around the image and have the have the right hand side of the image fade to the background color of the <div>. This will make the image appear to stretch the entire screen width, whatever the screen size.
