The method is used to get the number of pixels to the left of the page by which the webpage is displaced to the right. To calculate the current horizontal position of the webpage in pixels and window.pageXOffset values functions are used with the OR (|) operator because one of them may return 0 value in the browsers. Since some of browsers do not support the former method then this method comes as an alternative.Ĭalculating the current horizontal position of the page: The window.pageYOffset method of JavaScript also calculates the number of pixels from the top of the webpage by which the page is scrolled down. To calculate the current vertical scroll position of the web page in pixels and window.pageYOffset functions are used with OR (|) operator because one of them may return 0 value in some of the browsers.ĭ method of JavaScript calculates the number of pixels from the top of the webpage by which the page is scrolled down. To do this we need to fix the vertical and horizontal position of the page to the current values which can be done using the following JavaScript functions.Ĭalculating the current vertical position of the page: We can set the position of this windows.onscroll event to a fixed value then it will prevent the page from scrolling in the vertical or horizontal direction or both. The onscroll event on windows is triggered when the window's scrollbar is being scrolled. One of the ways to disable scroll on a webpage is using the window.onscroll event. By Overriding the window.onscroll Function The prerequisite for understanding this article is the basic understanding of CSS and JavaScript DOM methods like querySelector, and getElementById as well as adding the event listeners to HTML elements. We shall explore different methods to disable and enable the scrolling functionality of a webpage along with some example code snippets. We are able to see the text overflow into another area because the default value here is visible even though we did not specify that.Scrolling a webpage while navigating can be controlled by using some JavaScript and CSS or either one of them as well. In a real life project, this would be even more annoying because you'd have this text overlapping other elements on the page. The text can't fit into the white container so it overflows and crosses the container's border. Now have a look at what's happening with the container and the text: You could be working on a project and then realize that a piece of text crosses the border. The text sits comfortably in the white container without crossing the container's border on both axis. Then we made our paragraph's text color green. ![]() ![]() We set the background color of our div element which acts as a container to be white. ![]() We've given our page a background color of black.

Lorem ipsum dolor sit amet consectetur adipisicing elit. With this property, we can see our content clearly when it overflows into another area. This is the default value that the overflow property takes if none is specified. We will go over the following values of the overflow property and see how they work: When this happens, it makes the content "overflow" into another area, either horizontally (X-axis) or vertically (Y-axis). It helps us control what happens when an element's content is too big to fit into an area. In this tutorial, we will talk about an important CSS property – the overflow property.
