Hi All

Some developers suggest to create a home page component with some CSS and JAVASCRIPT and put it into the home page layout which will allow us to change the salesforce standard theme. (Blue color theme). Is this recomended. will this kind of thing affect the normal functionality if salesforce.com changed html structure in a new release.

Thanks.

sample for such a CSS and javascript shown below

document.getElementsByTagName('nav')[0].style.border="1px solid white";

document.getElementsByClassName('left')[0].style.visibility = 'hidden';

document.getElementById('phHeaderLogoImage').style.visibility = 'visible';

document.getElementsByClassName('right')[0].style.visibility = 'hidden';

document.getElementsByClassName('multiforce')[0].style.visibility = 'visible';

document.getElementsByTagName('nav')[0].style.borderTopLeftRadius = '.5em'; 

document.getElementsByTagName('nav')[0].style.borderTopRightRadius = '.5em'; 

document.getElementsByTagName('nav')[0].style.MozBorderRadiusTopleft = '.5em'; 

document.getElementsByTagName('nav')[0].style.MozBorderRadiusTopright = '.5em'; 

document.getElementsByTagName('nav')[0].style.WebkitBorderTopLeftRadius = '.5em';

document.getElementsByTagName('nav')[0].style.WebkitBorderTopRightRadius = '.5em';
