Hello td8000,
Navigate Additional CSS option and put below css into textarea then click on Save & Publish button.
#header h1.site-title {
font-size: 38px;
margin-top: -25px;
}
#header h2.site-description {
font-size: 28px;
}

If there no Additional CSS option or not work then put css code into you current active theme’s style.css file located at wp-content/themes/your_current_theme/ folder.
Note : All Changes you done in any file of theme are gone when you update theme. So prefer Child Theme.
Hope this will helps you.
