Inline Element V/S Block Element
In HTML we can display elements or group elements either in a single line or in a block for this we will use inline elements and block elements.
Block-Level Elements
Display Behavior:
Block-level elements occupy the full width available by default (from left to right in a parent container).
They start on a new line and push the following content to a new line.

you can see the text is written in different lines just because the heading element is a block element and takes the whole width
Dimensions:
- You can set the width, height, margin, and padding of block-level elements.
Usage:
- They are typically used for larger sections of content or structure.
Common Block-Level Elements:
<div>,<p>,<h1>,<h2>,<h3>,<ul>,<ol>,<table>,<section>,<article>,<footer>,<header>, etc.
<h1>examples of block element</h1>
<p>block element take whole width</p>
<section>
this is section tag
it is also a block element
</section>

again you can see in the above example we have used some block elements such as <p>, <h1>, and <section> and all the content is in a new line because the block element takes the whole width
Inline Elements
Display Behavior:
Inline elements only occupy the space needed for their content.
They do not start on a new line; instead, they flow along with the text and other inline elements within a block-level element.
Dimensions:
- You cannot directly set the width and height of inline elements. Only
paddingandmargin(horizontal) can be applied, but not vertical margins.
- You cannot directly set the width and height of inline elements. Only
Usage:
- Inline elements are typically used for smaller pieces of content, like formatting a few words within a paragraph.
Common Inline Elements:
<span>,<a>,<img>,<b>,<i>,<u>,<em>,<strong>,<abbr>,<code>, etc.
examples:
<span> This is inline element </span>
<a href="https://www.google.com">link is also a inline element</a>

The inline elements take up that much space which is needed for their content <span>, <a> tag in the above example takes only the required space unlike block elements
