Summary
the paradox comes in many forms. The most trivial one is a paralogy effect that reacts to the user’s scroll style. Today, I have sure to experiment on a different kind of parallax effect that proceeds to cursor development and mobile accelerator instead.
Suggest Interactive BG (Background), an item that will let you create a collective background or any fundamental on the page that proceeds to your cursor movement.
HOW TO USE INTERACTIVE BG
How does this work?
The approach is to apply the image as a training and move the background position bestow to the cursor’s position on moves over. First, I began to explore with a function that moves the backdrop position, but it spawn a little jaggedness in the energy when the cursor enters the image and the backdrop position needs to be reset to be moved.
This is not a good user training so in the end, I sure to use CSS3’s transform matrix, which allows me to act the background relative to the center equal without having to calculate it myself. Another advantage of using matrix is that I can also employ the scale and the position all in one go without accept to call and alive multiple values.
After I had ended a test on the desktop, I accomplished that this will not work on mobile because there is no mouse affair on smartphones and tablets, so rather of not supporting mobile, I pronounced to experiment on the new JS event called “device motion” which let me resolve the state of the accelerometer. After a few trials and errors, I was able to convert the “accelerationIncludingGravity” value into a usable data for my CSS3’s matrix transformation.
How-Tos
First and foremost, make sure you’ve contained the latest jQuery library (preferably 2.0.0 or higher) available here, and then include jQuery.interactive_bg.js which can be found here, into your document’s <head>. Make sure you have a training image in place so that you can allusion it in your code to be used as a collective background.
Now, let’s begin laying the markup:
Make sure you switch the
Make sure you switch the
data-ibg-bg attribute with the district of your prepared background image. For example, if your picture is in the root folder and is called “background.png”, change the attribute to”/background.png".Now, you can call the function as follows and your background will spring to life.

JS
- strength: This choice will let you control the background movement stamina when the cursor is moved. The higher the value, the faster and easier the cursor step the background. The default value is 25.
- scale: You can set the scale to which the background will be zoomed when on mouse hover. The choice accepts the normal CSS scale value so 1 means initial scale which will disable the scaling graphics on entrance and on exit. The default value is 1.05.
- animationSpeed: You can represent the time it takes for the escalate entrance and exit to be dynamic. The option welcome the CSS duration such as “100ms” or “2.5s”. The default value is “100ms”.
- contain: If you set the scale to be above than 1, this option, when set to true, will prohibit the enlarged objects/background from flow out of its container. Set this to false if you want the ratio content to spill out. The default value is true.
- wrapContent: This option lets you choose if you want every element inside the defined jar to react to your cursor or just the training. Toggle it to true to have every element central react the same way. The default value is false.

Interactive Background with Accelerometer
The great thing about this components is that you don’t have to do everything. The plugin will naturally detect when to apply the accelerometer effect instead of the conventional mouse events using data such as the time of the accelerometer events and the screen size. Try the demo on your smartphone and see for yourself.
