<h4>Summary</h4>
The Smooth Page Scroll Up/Down Buttons plugin for WordPress adds buttons to every page of your site, that can be used to (smoothly) scroll up or down exactly one screen/page at a time. This can be particularly handy for pages with a lot of text/content, or in cases wherever a browser’s scrollbar is just not good enough (or not present at all, like on tablets) to enable one-click, one-screen scrolling.
BONUS BUTTON! Optionally, you can add a “Back to top” button, that will take the visitor right back to the very top of the page.
No knowledge of any coding (HTML, CSS, JavaScript, PHP) is required at all.
<h4>Features</h4>
<ul>
<li>Button positioning: choose between three options of where you want the buttons to appear — next to eachother at the bottom right, on top of eachother at the bottom right, or one at the top right and the other at the bottom right.</li>
<li>Scrolling distance: scroll a full page with each click, half a page, or however far you want.</li>
<li>Button size: choose the size of the buttons.</li>
<li>Scrolling speed: set the speed at which pages should scroll from one page to another.</li>
<li>‘Back to top’ button: optionally, include an additional button that takes the user back to the very top of the page.</li>
</ul>
