Question

What is the best way to incorporate inline CSS using jQuery data attributes along with CSS3 prefixes?

This method works well for setting the background size using inline css like so:

style="background-size:cover"

$(".tp-sliderSection .item").css('background-size', function(){
  $(this).css('background-size',$(this).data("bg-size"));
});

<div data-bg-size="cover"></div>

However, I want to enhance it by adding more styles

$(".tp-sliderSection .item").css('background-size', function(){
  $(this).css('background-size',$(this).data("bg-size"));
  $(this).css('-webkit-background-size',$(this).data("bg-size"));
  $(this).css('-moz-background-size',$(this).data("bg-size"));
});

The desired output style in CSS would be

style="background-size:cover; -webkit-background-size:cover; -moz-background-size:cover"

And so on

Answer №1

If your original code isn't working as expected, consider using .attr() instead. I've noticed that sometimes there can be issues with .data(), but switching to .attr() often resolves them.

For more information, check out: http://api.jquery.com/css/:

Starting from jQuery 1.8, the .css() setter will automatically handle prefixing the property name. For example, using .css( "user-select", "none" ) in Chrome/Safari will set it as -webkit-user-select, while Firefox will use -moz-user-select and IE10 will use -ms-user-select.

Another issue you might be having is related to returning values. Make sure you are only returning the bg-size value without setting it again. If you already have a function for background-size, just return the value. You can take a look here for clarification: http://jsbin.com/xurevijunu/edit?html,css,js,console,output

Since jQuery 1.4, .css() allows the usage of a function as the property value:

$( "div.example" ).css( "width", function( index ) { return index * 50; });

This example sets the widths of the matched elements to incrementally larger values.

Note: If nothing is returned in the setter
function (ie. function(
  index, style ){} )
, or if undefined is returned, the current value is not changed. This is useful for selectively setting values only when certain criteria are met.

Therefore, you could try this approach:

$(".tp-sliderSection .item").css('background-size', function(){
  return $(this).attr("data-bg-size");
});
