how to do span in html code example

Example 1: span html

The HTML <span> element is a generic inline container for
pieces of content, which does not inherently represent anything. 
It is mostly used for grouping and styling bits of content.
<span> is very much like a <div> element, but <div> is a 
block-level element whereas a <span> is an inline element.

Example 2: html span

A <span> element used to color a part of a text:
  
<span style="font-size:30px">&#9776; </span> 
<!-- &#9776 is a color value -->
