How to reduce the size between title and subtext?

[tuanphan]

By default, the heading (title) always has a default margin, so you will see a space between the title (heading) and subtext (paragraph), like the screenshot.

To reduce this space, you can use below CSS code

h1, h2, h3 {
margin-bottom: 0px;
}
h1+p, h2+p, h3+p {
margin-top: 0px;
}
