1omegazip Hi
You are using custom code for font size in custom css
.acm-hero .hero-content .hero-content-inner h2 {
color: #ffffff;
font-size: 30px;
line-height: 1.333;
font-weight: 600;
}
to apply different code in screen size you need re define the code using media queries
Example you want above code to work till screen size is 992px
@media(min-width:992px){
.acm-hero .hero-content .hero-content-inner h2 {
color: #ffffff;
font-size: 30px;
line-height: 1.333;
font-weight: 600;
}}
To apply it on specific screen sizes
@media(max-width:1200px)and(min-width:992px){
.acm-hero .hero-content .hero-content-inner h2 {
color: #ffffff;
font-size: 30px;
line-height: 1.333;
font-weight: 600;
}}
