<p>Achievement of CSS style effects in web design

<p>Introduction:
CSS (Cascading Style Sheets) is a language for defining style and layout in web design. By using CSS, you can easily change the appearance and behavior of web page elements.

<p>How to achieve CSS style effects:

1. Add a style sheet:
   In HTML documents, use &lt ;link> tag to link to an external CSS file, or use the <style> tag to define inline styles within the document header.
2. Define selector:
   The selector is used to match HTML elements, such as #id, .class or element name (such as p).
3. Set attribute value:
   The selector is followed by curly brackets, which contains the style attribute to be applied to the matched element, such as color, font- size and background-color.

<p>Example:

<code class="html"><style>
  p {
    color: red;
    font-size: 20px;
  }
</style></code>

<p>This will make all <p> elements on the page red with a font size of 20 pixels Size display.

<p>Advanced CSS Effects:
In addition to basic styles, CSS also allows the creation of more advanced effects, such as:

• Transitions:When the attribute value of the element gradually changes over time.
• Animation: Create dynamic, visually appealing effects.
• Transformation: Change the shape or size of an element.
• Filters: Apply visual effects such as blur or hue shift.

<p>Best Practice:

• Use an external style sheet: This helps keep your HTML document clean and Ease of maintenance.
• Use semantic HTML: Apply CSS to HTML semantic elements rather than specific tags.
• Avoid too many inline styles: Inline styles can make code difficult to maintain.
• Use a CSS preprocessing language: Such as Sass or Less, which can simplify CSS code and add additional functionality.
