```htmlPage top
"Page top" — is a term that refers to the end of a webpage or document. A webpage typically consists of content arranged in a specific order, and at the very top, there are headings, logos, menus, or other elements that are visible immediately when the page is opened. Page top serves as a boundary between the visible content and the beginning of the page, which is not displayed until the user scrolls down.
Often, websites use a "scroll to top" button that allows users to scroll the page to the very top with a single click. This is particularly useful on pages with a large amount of content, such as news websites, online stores, and blogs. The "scroll to top" button is usually positioned in the bottom right corner of the screen and remains visible as the user scrolls down the page.
To add the "scroll to top" functionality to your website, you can use JavaScript. Below is an example code that will help you implement a "scroll to top" button on your site:
The above code includes both HTML and JavaScript. In HTML, we create a button with the ID "myBtn" and apply styles to it using CSS. Then, we define the `onscroll` event, which triggers when the user scrolls the page. If the scroll exceeds 20 pixels, the "scroll to top" button becomes visible. Otherwise, it remains hidden.
In JavaScript, two functions are defined: `scrollFunction()` and `topFunction()`. The first function checks the page scroll and, depending on the scroll value, shows or hides the "scroll to top" button. The second function is executed when the "scroll to top" button is clicked and it scrolls the page to the top by setting the `scrollTop` to 0.
You need to insert this code into the desired location of your webpage. You can also customize the button styles by adding your own CSS classes.
This code example will help you add the "scroll to top" functionality to your website. Keep in mind that this code is just an example, and you may need to adapt it to your specific needs and usage conditions.
