Question: I'm developing a website based on WordPress source code through XAMPP. Sometimes I change the CSS code, scripts or something else and I notice my browser takes time to apply the modifications. This leads me to use multiple browsers to refresh one and if it doesn't apply the new styles I try the second one and it's always this.

There is some way of avoiding this problem?

Sometimes I'm changing code without noticing the previous modifications.

Answer: 
You can turn off caching with Firefox's web developer toolbar.
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.
