HTML Headings from Largest to Smallest : "h1 to h6"

HTML heading tags (<h1> to <h6>) are structural elements used to define headings or titles within a document. By default, browsers apply certain styles to these heading tags, and these styles can vary slightly between browsers. Here's a general overview of the default styles for heading tags.

Font Size:

• Each heading tag has a default font size, with <h1> being the largest and <h6> the smallest. The font size decreases as the heading level increases.

h1 {
   font-size: 2em; /* Typically larger */
}

h2 {
   font-size: 1.5em;
}

h3 {
   font-size: 1.17em;
}

h4 {
   font-size: 1em;
}

h5 {
   font-size: 0.83em;
}

h6 {
   font-size: 0.67em; /* Typically smaller */
}

Margin and Padding:

• The default margins and padding around heading tags may vary between browsers. It's generally a good practice to reset or normalize these styles using a CSS reset or a CSS framework like Normalize.css to ensure consistent styling across different browsers.

h1, h2, h3, h4, h5, h6 {
  margin-top: 0.67em;    /* Adjusted for spacing between headings and other elements */
  margin-bottom: 0.67em; /* Adjusted for spacing between headings and other elements */
}

Font Weight:

• Heading tags often have a bold font weight by default, emphasizing their role as headings.

h1, h2, h3, h4, h5, h6 {
  font-weight: bold;
}

Line Height:

• The default line height may vary, but it is often set to provide a visually pleasing spacing between lines of text within a heading.

h1, h2, h3, h4, h5, h6 {
  line-height: 1.2; /* Adjusted for good readability */
}

It's important to note that these values can be affected by user-agent stylesheets and may be overridden by custom styles in your CSS. To ensure consistent styling and improve cross-browser compatibility, web developers often use a CSS reset or normalization techniques at the beginning of their stylesheets. This helps create a consistent baseline for styling across different browsers and devices.
