I'm wanting to have a message on every page that I can change with ease. I'm very new to JS but have worked with HTML and CSS for over 3 years now.
This is what I've got so far.
<p>NEW!!! - GO CLICK <a href="#">HERE</a> FOR DETAILS</p>
I discovered that I can create a single line of script code that will run a .js file.
document.write("<p>This is my message.</p>");
Works well and does exactly what I wanted to do. Thank you to all who helped.
