I\'m developing a website based on Wordpress source code through XAMPP. Sometimes I change the CSS code, scrips or something else and I notice my browser takes time to apply
Try this:
link href="styles/style.css?=time()" rel="stylesheet" type="text/css"
If you need something after the '?' that is different every time the page is accessed then the time() will do it. Leaving this in your code permanently is not really a good idea since it will only slow down page loading and probably isn't necessary.
I've found that forcing a style sheet refresh is helpful if you've made extensive changes to a page's layout and accessing the new style sheet is vital to having something sensible appear on the screen.
