The way Responsive Logos adjust their image width when you resize the browser is truly impressive. It seems like they are using SVG images, but I'm not entirely sure how they are able to make the image change dynamically. Could it be through the CSS code provided at the end of the source?
@media only screen and (min-width: 15em) {
.logo1, .logo2, .logo3, .logo4, .logo5, .logo6, .logo7, .logo8 {background-position: left -900px;}
}
@media only screen and (min-width: 28em) {
.logo1, .logo2, .logo3, .logo4, .logo5, .logo6, .logo7, .logo8 {background-position: left -600px;}
}
@media only screen and (min-width: 45em){
.logo1, .logo2, .logo3, .logo4, .logo5, .logo6, .logo7, .logo8 {background-position: left -300px;}
}
@media only screen and (min-width: 60em){
.logo1, .logo2, .logo3, .logo4, .logo5, .logo6, .logo7, .logo8 {background-position: left 0px;}
}
Your assistance on this matter would be greatly appreciated!
