There are a number of frameworks that can be used to assist in developing & designing websites today. One of the most popular is Twitter’s Bootstrap, which takes a mobile-first approach.
Below are the basic media queries for both Bootstrap 3.0 and Bootstrap 2. You can use these as a good starting point for your site customizations (note that I’ve included non-mobile-first order for Bootstrap 3 as well, since some sites don’t use that particular method of designing sites).
/*==================================================
= Bootstrap 3 Media Queries =
==================================================*/
/*========== Mobile First Method ==========*/
/* Custom, iPhone Retina */
@media only screen and (min-width : 320px) {
}
/* Extra Small Devices, Phones */
@media only screen and (min-width : 480px) {
}
/* Small Devices, Tablets */
@media only screen and (min-width : 768px) {
}
/* Medium Devices, Desktops */
@media only screen and (min-width : 992px) {
}
/* Large Devices, Wide Screens */
@media only screen and (min-width : 1200px) {
}
/*========== Non-Mobile First Method ==========*/
/* Large Devices, Wide Screens */
@media only screen and (max-width : 1200px) {
}
/* Medium Devices, Desktops */
@media only screen and (max-width : 992px) {
}
/* Small Devices, Tablets */
@media only screen and (max-width : 768px) {
}
/* Extra Small Devices, Phones */
@media only screen and (max-width : 480px) {
}
/* Custom, iPhone Retina */
@media only screen and (max-width : 320px) {
}
/*=====================================================
= Bootstrap 2.3.2 Media Queries =
=====================================================*/
@media only screen and (max-width : 1200px) {
}
@media only screen and (max-width : 979px) {
}
@media only screen and (max-width : 767px) {
}
@media only screen and (max-width : 480px) {
}
@media only screen and (max-width : 320px) {
}
I hope these are useful. If you use a different set of media queries for Bootstrap, please discuss below.
