How to fit content?

How can I make content fit to the screen? It should fit to the screen without any overflow and no content being cut. Currently, even though my content does not fill the entire width of the screen, there is still overflow and horizontal scrollbar appears. How can I adjust the content so that it is within the width of the screen so that no scrollbar appears?

@Subhan95 are you using <meta name="viewport" content="width=device-width, initial-scale=1"> in your header?
If that’s not the solution, could you post a link to your code?
