Hey Robert,
The headlines except for the entry title are not responsive out of the box. You will need to setup the responsive text globally in Theme Options > Typography.

Then, if you still don’t like the overall outcome of the global responsive text, you can use the Responsive Text shortcode to individually target each of your headline in your page to have font size control thus controlling how the specific headline flows in your content.
If you want to change the size of the headlines globally, regretfully, you will need custom CSS like the CSS below. It uses rem
unit so it will still be based on the font-size
setting in Typography. You will just be overriding the scale. You can use other scalable font size units like em
and %
but I won’t be going through that because that would need further technical explanation. Please watch the screencast in the secure note for explanation.
.entry-content h1 {
font-size: 2.1rem;
}
.entry-content h2 {
font-size: 1.9rem;
}
.entry-content h3 {
font-size: 1.7rem;
}
.entry-content h4 {
font-size: 1.4rem;
}
.entry-content h5 {
font-size: 1.2rem;
}
.entry-content h6 {
font-size: 1rem;
}
Please just note though that issues that might arise from the use of the custom CSS and further enhancements are not a part of our support. Headline sizing control is a known feature request so there might be an official option in the future.
Thanks.
