Parallax Websites Take User Experience to a Whole New Level
Parallax websites are all about getting the right user experience. The smooth scrolling experience makes even the lengthy pages look impressive. It’s the perfect ingredient for a memorable website user experience. No wonder that these websites are often very good at conversion.
7 Pro Tips for Parallax Websites
- Depth Correction – Parallax websites are all about creating the right depth using the 3D effect. When an element is represented on the screen using the Z axis, the size effectively changes as the viewpoint shifts closer or farther from the axis. To take care of this effect, a Scale() is applied to the element so that the image can be rendered clearly. At every viewpoint, the image is always visible from the original size. To calculate the Scale() factor, use 1 + (translateZ * -1) / perspective.
- Layer Speed Control – Z translation values and perspective are used to control the speed of the layers. Elements that scroll slower have a negative Z value and faster scrolling elements have a positive Z value. The parallax effect can be increased by taking the Z value further from the 0.
- Parallax Sections – This is an advanced concept that has recently seen great success. The same page can have different parallax effects. The page is broken into distinct sections and different effects can be applied as per the requirements. Different Z values can be set for every group and a new style/effect can be achieved for the various sections. But there’s a catch! When the elements are grouped, the content of a group cannot be clipped. If you try to set Overflow: hidden, the parallax effect will be broken by the group. This unclipped content will lead to descendant elements to overflow. This has to be done very carefully by being cautious with the Z index value groups to make sure that right content is hidden and revealed to the user scrolling through the webpage.
- Mobile Optimized or Responsive – You have to take an approach in this case. For example whether you want mobile optimized or want to turn off the scrolling animations for smartphones. A developer must first ensure that the scrolling library and effects are implemented after the site is made responsive. Videos from parallax websites are not played automatically on mobiles. So, there should be a fall back image in place for such situations. For effective smartphone optimization, it is recommended to disable scrolling effects.
Parallax websites are all about savoring the experience. But it has to be done correctly to take advantage of the impressive features. Follow these pro tips and you will be doing good in no time. For one thing is sure that parallax websites are here to stay. So make the most of this amazing design trend.
