logo missing

Hi there

Which type of graphic are you wanting to use? Will be an image or an icon say FontAwesome?

well I found a nice png image online but would it be better to do an icon?

You can use a PNG if it works for you, icons are generally better when scaled to small or large sizes. But you can try this:

<a href="tel:123-456-7890"><img src="full/URL/to_image.png" alt="phone" height="40" width="40"></a>

Just update the URL and the height width you want it.

okay everything works however if you look at the phone icon and logo at the top on a mobile phone, everything is off to the right and not centered. How do I center everything?

Can you try using the same left and right padding for the header?

Currently only the left has 40px which is making the elements not centered.

Let me know :)
