I'm building a small website, where.. when a user clicks on one of the menus, the current css layout must change and new css layout must be formed without page reload. what i meant to say was, the banner remains the same but the complete css layout below it is re-deployed[the CSS file containing the layout below the banner reloads]. This must happen without a HTML page reload. How can i achieve this? I'm currently thinking of having 2 different CSS files. But how to apply CSS without reloading a page?
Thanks in advance.
