I would like to make the title of posts slightly smaller and the space between the title and the content of the post smaller . I thought this was the bit of code I needed to add to the child css file and edit but it doesn't seem to make any difference so I must have got the wrong code. Could someone tell me which line of the parent theme code would allow me to edit the size of the post title?
Here's the code I used:
margin:6px 0 0 0;
