- Content Management Systems (CMS): Utilizes platforms like WordPress or Joomla for quick content updates without extensive coding.
Key Technologies Used in Web Development
Front-End Technologies: HTML, CSS, and JavaScript
Front-end development is pivotal in web development, utilizing three main technologies:
- HTML (HyperText Markup Language): The backbone of web content, defining the structure of a webpage.
- CSS (Cascading Style Sheets): Used to style the visual presentation of the website, including layout, colors, and fonts.
- JavaScript: A powerful programming language that allows for dynamic content, such as interactive forms and animations.
These technologies work in conjunction to provide an engaging user experience, with HTML providing the structure, CSS the style, and JavaScript the interactivity.
Back-End Development: Server-Side Programming Languages
The back-end of a website is critical for functionality, managing server operations and database interactions. Common programming languages used include:
- PHP: A widely-used scripting language for server-side programming.
