I am tweening my navbar in by height, is this a good idea?


I am asking that because I am worried if javascript were to fail for the user the navbar would never show.

Hi LazyRectangle  :)


Welcome to the GreenSock forums. 


It's always good practice to have a fallback for those scenarios. You can set up a check if the user has JavaScript disabled and if they do you can set the height of the nav bar via your CSS. Modernizr makes that pretty easy for you.




You can also use a <noscript> tag to display a message for those users as well. 


Hopefully that helps a bit.


Happy tweening and thanks for being a Club GreenSock member.

Thanks for that reply PointC, that is the answer i needed. I am pretty new to web stuff so i'm still finding my feet.


GSAP is great and it's good to know they have a good forum.
