A little snip of code

This little bit of code is what I am using when it comes to doing the headings, their color and border, aswell as giving the border themselves a colour and size. NOTE: The headings themselves are just named "Heading 1" and "Heading 2" just as placeholders.

 <h1 style="border: 2px solid aquamarine;">Heading 1</h1>
  <h2 style="border:2px solid aquamarine;">Heading 2</h2>
  <style>
table {
  font: Times New Roman;
  border-collapse: collapse;
  width: 100%;
  font-size: 100%;
  margin: 50px;
