Change heading font size

I want to change the H2 font size of this post: https://akaricitybinhtan.com/tien-do-du-an-akari-city-binh-tan-thang-5-2018/
I using this CSS:
h1, h2,h3, h4, h5, h6 {
font-size: 25;
font-family: “sans-serif”;
font-weight: bold;
color: black;
}
but it’s the “font-size” takes no effect.
Thank you for supporting!

Hey there

You are almost there, you just need to add px to 25 :slight_smile: this is final code:

h1, h2,h3, h4, h5, h6 {
font-size: 25px;
font-family: “sans-serif”;
font-weight: bold;
color: black;
}

Thank you!!!
