</body>
</html>

Explanation:

This HTML and CSS code combination creates a speech bubble shape using CSS3.
The speech bubble consists of a main container div and a pseudo-element (::before) to create the arrow or triangular shape.
The main container div has a specified width, height, background color, and border radius to create the body of the speech bubble.
The pseudo-element is positioned absolutely relative to its container and is used to create the arrow shape using borders.
By adjusting the border properties of the pseudo-element, you can control the size and shape of the arrow.
The positioning of the pseudo-element is calculated using margins to align it properly with the speech bubble body.
