HTML & CSS: Building and Styling Webpages

Basic Structure: Defines the essential boilerplate for any HTML document, including the document type declaration, root element, metadata section, and visible page content.

: Declares the document type and version.

: The root element for the entire HTML page.

: Contains meta-information about the document, like character set and title.

: Encloses all the visible content of the webpage.

: Sets the title that appears in the browser tab or window.</span> </li> <li class="flex items-start"> <div class="flex-shrink-0 w-1.5 h-1.5 sm:w-2 sm:h-2 bg-primary-500 rounded-full mt-2 sm:mt-2.5

features?</h2>  <p class="text-base sm:text-lg mb-4 sm:mb-5 lg:mb-6">CSS, or Cascading Style Sheets, is the language used to describe the presentation of a document written in HTML. It dictates how HTML elements are displayed on screen, paper, or in other media, covering aspects like colors, fonts, layout, and responsiveness. By separating the document's content from its visual presentation, CSS allows for greater control over design, making websites visually appealing and consistent across different devices and browsers. This separation also streamlines development, enabling designers to update the look of an entire website from a single stylesheet without altering the underlying HTML structure.</p>  <ul

lg:mb-6">The relationship between HTML and CSS is fundamental and symbiotic in web development, akin to a building's structure and its interior design. HTML provides the essential framework and content, defining the logical organization of a webpage with elements like headings, paragraphs, and images. CSS then takes this raw structure and applies all the visual styling, including colors, fonts, spacing, and layout. This clear separation of concerns allows developers to manage content and presentation independently, leading to more maintainable, flexible, and accessible websites. Without HTML, there's no content to style; without CSS, HTML appears as plain, unformatted text.</p>  <ul class="space-y-2 sm:space-y-3 mb-4 sm:mb-5 lg:mb-6"> <li class="flex items-start"> <div class="flex-shrink-0 w-1.5 h-1.5 sm:w-2 sm:h-2 bg-primary-500 rounded-full mt-2 sm:mt-2.5 mr-2 sm:mr-3"></div> <span class="text-base sm:text-lg">HTML provides the structure: Defines the fundamental content and logical organization of a webpage, acting as the skeleton.</span> </li> <li class="flex items-start"> <div class="flex-shrink-0 w-1.5 h-1.5 sm:w-2 sm:h-2 bg-primary-500 rounded-full mt-2 sm:mt-2.5 mr-2 sm:mr-3"></div> <span class="text-base sm:text-lg">CSS provides the styling: Applies all visual presentation, including layout, colors, and typography, to that structured HTML content, acting as the skin and aesthetics.</span> </li> </ul> </div> </div> </div> </div> </section>  <section class="mb-8 sm:mb-12 lg:mb-16 max-w-5xl mx-auto px-4 sm:px-6 lg:px-0"> <div class="bg-white rounded-xl sm:rounded-2xl overflow-hidden"> <div class="mx-auto">  <h2 class="text-xl sm:text-2xl lg:text-3xl font-bold text-gray-900 mb-6 sm:mb-7 lg:mb-8"> Frequently Asked Questions </h2>  <div class="space-y-4 sm:space-y-5 lg:space-y-6"> <div class="bg-white rounded-lg sm:rounded-xl p-4 sm:p-5 lg:p-6 shadow-sm border border-gray-100"> <div class="space-y-3 sm:space-y-4">  <div class="flex items-start sm:items-center space-x-2 sm:space-x-3"> <div class="flex-shrink-0 w-5 h-5 sm:w-6 sm:h-6 bg-blue-600 text-white rounded-md sm:rounded-lg flex items-center justify-center mt-0.5 sm:mt-0"> <span class="text-xs sm:text-sm font-bold">Q</span> </div> <h3 class="text-base sm:text-lg font-semibold text-gray-900 flex-1 leading-tight sm:leading-normal">What is the primary function of HTML in web development?</h3> </div>  <div class="ml-7 sm:ml-9 pl-2 sm:pl-3 border-l-2 sm:border-l-3 border-green-200"> <div class="flex items-start space-x-1.5 sm:space-x-2"> <div class="flex-shrink-0 w-4 h-4 sm:w-5 sm:h-5 bg-green-500 text-white rounded sm:rounded-md flex items-center justify-center mt-0.5"> <span class="text-xs font-bold">A</span> </div> <p class="text-sm sm:text-base lg:text-lg text-gray-700 leading-relaxed">HTML defines the structure and content of a webpage using elements and tags.
