In jQuery, fontSize and font-size are both valid in the css() function, but in animate(), it has to be fontSize?

In jQuery, fontSize and font-size are both valid in the css() function, but in animate(), it has to be fontSize?

Are there more rules for other functions?

so the safest is still the form fontSize

Update: our project uses jQuery 1.3.1, and it will not work... but I just checked that 1.4.2 will work with "font-size" even for animate.

Solution

  • from the .animate() API page:

    The .animate() method allows us to create animation effects on any numeric CSS property. The only required parameter is a map of CSS properties. This map is similar to the one that can be sent to the .css() method, except that the range of properties is more restrictive.
