My published posts have an unwanted space and a faint line under every heading – whether I use H1, H2, H3, H4 or H5 sizing for the text. The formatting looks fine in draft form but in preview and publishing there is excess white space. How do I remove this please? Here is an example: http://mylowerbloodpressure.com/foods-to-avoid/does-caffeine-raise-blood-pressure.
The code you provdided to put in the CSS section did not correct this. Thanks.
