Hi so i'm making a e-mail signature but i need to be able to edit the text in outlook does the editing of text vary from email program to email program or is it a piece of code in html

so i am new to js and i made myself a sticky nav with the help of a guide but i tried to apply it on to the image in the nav as well to make it have a opacity of 0 or 1 whenever it hits the top of my browser window in chrome it adds the class and removes it but the img just stays hidden i don't know why the sticky nave works fine but the css just wont adjust on the img http://pastebin.com/ELNQdwWF
