Hi there,
Welcome to SeaTheme forum.

1. Please paste the custom CSS code to “Appearance > Customize: Additional CSS”:

div[data-post="20210111-201057-156"] h4 {
border: 1px solid; display: inline-block; padding: 10px; margin-bottom: 20px;
}

2. For the classes page, I found you add several fullwidth wrap.
You can use the custom CSS to define different spacing with anchor name of a fullwidth(with Enable Bottom Inner Spacer and Enable Bottom Outer Spacer)

#private-sessions.bottom-space-40-in{
	padding-bottom: 60px;
}
#private-sessions.bottom-space-40{ 
   margin-bottom: 40px; 
}

60 and 40 are the default value, please adjust them.

Regards!

If you want to add border to all Text, please update the CSS to:

div[data-post="20210111-201057-156"]  {
 border: 1px solid; display: inline-block; padding: 10px;  
}
