Force browser to refresh css, javascript, etc
===

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 the modifications. This leads me to use multiple browsers to refresh one and if 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 notice the previous modifications.

Thank you!
