== Parallax scrolling in Web design ==
One of the first implementations of parallax scrolling in the browser was created and shared in a blog post by web developer Glutnix in 2007, this included example code and a demo using JavaScript and CSS&nbsp;2 that supported Internet&nbsp;Explorer&nbsp;6 and other browsers of that era.<ref>{{cite web|title=Parallax Backgrounds - a multi-layered javascript experiment|url=https://inner.geek.nz/archives/2007/03/20/parallax-backgrounds/|work=Glutnix|publisher=inner.geek.nz|access-date=28 June 2019|author=Brett Taylor|date=20 March 2007}}</ref><ref>{{cite web|title=Showcasing the css parallax effect - 12+1 creative usages|url=https://kremalicious.com/showcasing-the-css-parallax-effect-12-creative-usages/|work=Glutnix|publisher=kremalicious.com|access-date=28 June 2019|author=Matthias Kretschmann|date=23 May 2008}}</ref> However, it wasn't until 2011 and the introduction of [[HTML5]] and [[Cascading Style Sheets#CSS 3|CSS&nbsp;3]] [[Computer programming|coding]] that the technique became popular with [[World Wide Web|Web]] designers. Advocates argue it is a simple way to embrace the fluidity of the Web.<ref name="CederholmMarcotte2010">{{cite book|author1=Dan Cederholm|author2=Ethan Marcotte|title=Handcrafted CSS: More Bulletproof Web Design|url=https://archive.org/details/handcraftedcssmo0000cede|url-access=registration|date=9 April 2010|publisher=New Riders|isbn=978-0-13-210481-4|pages=[https://archive.org/details/handcraftedcssmo0000cede/page/5 5]–}}</ref>

Proponents use parallax backgrounds as a tool to better engage users and improve the overall experience that a website provides. However, a [[Purdue University]] study, published in 2013, revealed the following findings: "... although parallax scrolling enhanced certain aspects of the user experience, it did not necessarily improve the overall user experience".<ref>{{cite journal|title=The Effects Of Parallax Scrolling On User Experience And Preference In Web Design|url=https://docs.lib.purdue.edu/cgttheses/27/|journal=Purdue University|access-date=17 April 2014|author=Dede M.

A undated study occurring during or after 2010 by Dede Frederick, James Mohler, Mihaela Vorvoreanu, and Ronald Glotzbach noted that parallax scrolling "may cause certain people to experience nausea."<ref>{{Cite journal|last=Frederick|first=Dede|title=The Effects of Parallax Scrolling on User Experience in Web Design|journal=Journal of User Experience|volume=10|issue=2}}</ref>
