Change font size for my collection pages (H1, H2, H3)

[Rebekah82]

Hi, we are using an external 3rd party theme - and I would love to change the font sizes for all of our HEADINGS (H1, H2, H3, H4) in the Rich Text Editor when loading content/copy for our collection pages.

How can assign different font sizes for our headings??

/============================================================================

==============================================================================/

h1, h2, h3, h4, h5, h6 {
display: block;
@include headerFontStack;
margin: 0 0 ($gutter / 4);

a {
text-decoration: none;
font-weight: inherit;
}
@include media-query($medium-up) {
margin: 0 0 ($gutter / 2);
}
}

h1 {
font-size: em(floor($type_header_base_size * 0.85));
@include media-query($medium-up) {
font-size: em($type_header_base_size);
}
}

h2 {
font-size: em(floor($type_header_base_size * 0.9 * 0.85));
@include media-query($medium-up) {
font-size: em(floor($type_header_base_size * 0.9));
}
}

h3 {
font-size: em(floor($type_header_base_size * 0.85 * 0.85));
@include media-query($medium-up) {
font-size: em(floor($type_header_base_size * 0.85));
}
}

h4 {
font-size: em(floor($type_header_base_size * 0.54 * 0.85));
@include media-query($medium-up) {
font-size: em(floor($type_header_base_size * 0.54));
}
}

h5,
h6 {
font-size: em(floor($type_header_base_size * 0.5));
}

.h1 { @extend h1; }

.h2 { @extend h2; }

.h3 { @extend h3; }

.h4 { @extend h4; }

.h5 { @extend h5; }

.h6 { @extend h6; }

// Standardize text spacing sometimes

.text-spacing {
margin-bottom: $gutter / 2;
}

@Rebekah82 ,

1. In your Shopify Admin go to online store > themes > actions > edit code
2. In your theme.liquid file, find the (press CTRL + F or command + F on Mac)
3. paste this code right above the tag:

h1{
    font-size: 20px;
}

h2{
    font-size: 19px;
}

h3{
    font-size: 18px;
}

h4{
    font-size: 17px;
}

h5{
    font-size: 16px;
}

h6{
    font-size: 15px;
}

@media (max-width: 767px){
    h1{
        font-size: 20px;
    }
    
    h2{
        font-size: 19px;
    }
    
    h3{
        font-size: 18px;
    }
    
    h4{
        font-size: 17px;
    }
    
    h5{
        font-size: 16px;
    }
    
    h6{
        font-size: 15px;
    }
}

You can change the values as per your wish. The ones below the “media” line are for mobile devices.

Kind regards,
Diego

Sorry this wouldn’t work. The code needs to be changed in the: Assets > theme.scss.liquid

@Rebekah82

You can move the code to theme.scss. Why exactly wouldn’t it work?

Thank you so much, worked straight away!
