Question

I have 2 divs, 70% and 30% widths, within a 100% width containing div. On click I want the 70% div to change to 100% width and ‘slide over’ the 30% div and on second click retract back to 70% and reinstate the 30% div. I’ve half achieved the desired effect below; it ‘slides over’ the smaller div but retains it’s 70% width. I can’t get the width to expand to 100% without having a stutter animation as I’ve invoked the width change after the toggle or it expanding to 100% but the other 30% div still being visible and knocking the divs onto 2 lines.

I did see another similar question that works but they are static widths and I couldn’t successfully convert them into percentages without the above problems cropping up again.

$('#trigger').click(function() {

$('#sidebar').animate({width: 'toggle'});

});​

JS – Second Attempt

$('#trigger').toggle(function() {
    $('#sidebar').animate({width: '+=22em'});
    $('#activity').animate({width: '-=22em'});
},function() {
    $('#sidebar').animate({width: '-=22em'});
    $('#activity').animate({width: '+=22em'});
});​

Answer 1

You can do something like this?

http://jsfiddle.net/kjDYh/2/

basically set the nav to 0px and main to 100%?

$('#trigger').toggle(function() {
    $('#sidebar').animate({width: '100%'});
    $('#activity').animate({width: '0px'});
},function() {
    $('#sidebar').animate({width: '70%'});
    $('#activity').animate({width: '30%'});
});​
