i'm creating some forums type task so i want to display the notifications botom of the page for few seconds like facebook notifications which is posted by the students so how can i can anyone help me :) :)

php might be involved but to display something on page for a few seconds is a task for javascript so maybe you need to start this thread in that forum to get the best chance of a relevant and timely answer i also recommend using punctuation in your post as if you are too lazy or impatient to explain your problem clearly you are also probably too lazy and impatient to write your code properly and it will be a painful thing to help you
