the question about footer color

how can I change the footer color ? set background in CSS? which part of css can I change ?Thanks

It depends on the skin you use. For default skin: div.gridbox div.ftr td, for other skins div.gridbox_[skin name] div.ftr td

thanks. how I can format the total of footer in 2 decimal place (0.00)???

If this mask is applied to the whole column:

mygrid.setNumberFormat(“0.00”,COLUMN_INDEX);

you can try to use the following approach:
 
mygrid.attachEvent(“onStatReady”,function(){

     mygrid.ftr.rows[1].cells[COLUMN_INDEX].innerHTML = mygrid._aplNF(mygrid.ftr.rows[1].cells[COLUMN_INDEX].innerHTML,COLUMN_INDEX);

})
 
The COLUMN_INDEX is index of formatted column. onStatReady is internal event. It occurs when footers’ values are calculated.
