WP Spectrum Theme: Logo Height & Widget Position in Header

Hello

I am trying to make two changes to a new website I am building. I am stuck and would appreciate any help.

With both issues I can correct them with the help of Firebug however when I try and find out where the code is within multiple files I get stuck. Common sense would tell me that references to the logo an header widget position would be in the header.php, but I cannot find the lines of code I need there.

Problem 1: I need to adjust the logo height (not the image size)(which I can do in firebug by adjusting the height number in the code).

Problem 2: I need to adjust the position of the Telephone number widget (which I can do in firebug by adjusting the column number in the code)

Please could someone help me locate these lines of code in my files which I am accessing by FTP.

When using firebug CSS is really easy to find because it shows the file name and line number. Why is HTML always so difficult to find?

Thanks in advance for your help

Mike
