<p><strong style="color: rgb(187, 187, 187);">CSS </strong><span style="color: rgb(187, 187, 187);">(Cascading Style Sheets) is a web technology that provides the browser with a style for displaying different elements of web pages1. CSS allows you to control the properties of web pages, such as colour, font, background, border, position and size, and to improve the design.</span></p><p><br></p><p><span style="color: rgb(187, 187, 187);">To use CSS, you need to add a &lt;style&gt; tag to the &lt;head&gt; section of your HTML document. Inside this tag you can write your CSS code. There are two basic parts to CSS code: the selector and the declaration. The selector specifies the HTML element you want to style. The declaration shows what properties the element has and how to change them.</span></p><p><br></p><p>Example CSS code:</p><p><br></p><pre class="ql-syntax" spellcheck="false">&lt;style&gt; 
h1 { 
/* h1 selector 
/ color: blue; 
/ colour declaration 
/ font-size: 36px; 
/ font size declaration /
 } 
p {
 / p selector / color: red;
 / colour declaration 
/ font family: Arial; 
/ font declaration */
 } 
&lt;/style&gt;.
</pre><p><br></p><p><span style="color: rgb(187, 187, 187);">In this code, we have specified that the colour of the h1 headings is blue and the font size is 36px, the colour of the p paragraphs is red and the font is Arial. This is how we changed the appearance of our web page.</span></p><p><br></p><p><span style="color: rgb(187, 187, 187);">CSS allows you to easily control the design of your web pages, giving them a more professional and aesthetic look.</span></p>
