Can't Change Heading 1 font size

Hi,

I have been trying to change the “H1 Font Size” in Sydney’s customization from so many days but I am not able to. No matter what number I put in there, the heading font size doesn’t change.
I can change the “Body font size”, “Menu Items” and other headings size except H1.

I tried changing it from “style.css” by increasing the font size as shown below, but it was of no help.

“.page-title h1 {
margin: 0;
font-size: 52px;
color: #ccc;”

I think this is a bug, please fix it. If it is not, then kindly help me.
I can attach the screenshot if required.

Hi,

In your styles.css file, please use these below code instead:

.page h1.title-post {
  margin: 0;
  font-size: 52px;
  color: #ccc;
}

Regards,
Awan
