In order to use this method you have to put the c-box text to every container. But then it allows you to change all of them from one place and you keep the freedom to do a few container manually, because if you don’t put in the c-box value then it simply doesn’t apply. And ofcourse the big benefit that you can add multiple breakpoints. So you can even add more than what I have over here.
<style>
/* CONTAINER BOXED LAYOUT*/
/* Ultra wide */
@media (max-width: 3840px) {
.c-box {--content-width: 55%;}}
/* Desktop */
@media (max-width: 1920px) {
.c-box {--content-width: 65%;}}
/* Laptop big */
@media (max-width: 1600px) {
.c-box {--content-width: 74%;}}
/* Laptop small */
@media (max-width: 1366px) {
.c-box {--content-width: 77%;}}
/* Tablet portrait */
@media (max-width: 1200px) {
.c-box {--content-width: 80%;}}
/* Mobile */
@media (max-width: 767px) {
.c-box {--content-width: 85%;}}
</style>
