improve border in faqs (#481)

Under #448 assigned to me , I improved border of faqs section

As discussed earlier, The current border in FAqs was very plain simple
white border which looks plain and unattractive.
I made it more attractive, I added glowing moving gradient borders, as
you can see in the video it looks beautiful and eye-catchy
