I created a website using HTML, CSS and JS. I have a problem when i created a html page using iframe in that i am displaying some text that exceeds the fixed size of the iframe and creating scroll bar but i want to hide the scrollbar but it should have to scroll. I used the following code in CSS as follows, ::-webkit-scrollbar { display: none; }. It is working in Chrome browser, but not supporting in firefox is there any alternative code to solve this problem in firefox.
