navigation bar help!!

Well, it would be helpful if you could share the specific layout, but as this is not the case, I can only share the generic answer.

Most of the time the glow effect is the "shadow" property on the CSS parts. So, if its only the top text, imagine its something like this

.top-text-glow {
  text-shadow: [SHADOW PROPERTY];
}

Just delete it and thats it.

thank you
this is the specific layout im using
