Create a simple html page with 2-second refresh

I don’t really have experience with html/js/php programming but just did a simple page for my station. Besides a main html, I added a realtime page using steel gauges. WD is uploading customclientraw.txt to my server every 2 or 3 seconds.
Is there a (really) simple way to set up a html/php page that would update the parameters from the customclientraw.txt in the same way as the steelgauges do? I could modify the steelgauges page but I just want to keep my page really simple and small.
Thanks!

I PM’d you some code that may help.
