``` ### CSS Files **Reset CSS (reset.css)**: This file resets the default browser styles to ensure consistency across different browsers. ```css /* Reset default browser styles */ html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video { margin: 0; padding: 0; border: 0; font-size: 100%; font: inherit; vertical-align: baseline; } /* HTML5 display-role reset for older browsers */ article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section { display: block; } body { line-height: 1; } ol, ul { list-style: none; } blockquote, q { quotes: none; } blockquote:before, blockquote:after, q:before, q:after { content: ''; content: none; } table { border-collapse: collapse; border-spacing: 0; } ``` **Main CSS (main.css)**: This file contains the main styles for your landing page. ```css /* Global Styles */ body { font-family: Arial, sans-serif; line-height: 1.6; margin: 0; padding: 0; background-color: #f4f4f4; color: #333; } /* Header Styles */ header { background: #333; color: #fff; padding: 1rem 0; text-align: center; } header .logo img { max-width: 100px; } header nav ul { display: flex; justify-content: center; list-style: none; padding: 0; } header nav ul li { margin: 0 1rem; } header nav ul li a { color: #fff; text-decoration: none; font-weight: bold; } /* Hero Section */ .hero { background: #fff; padding: 2rem; text-align: center; } .hero h1 { margin-bottom: 1rem; font-size: 2.5rem; } .hero p { font-size: 1.2rem; } /* Features Section */ .features { display: flex; justify-content: space-around; padding: 2rem; background: #e9e9e9; } .feature { flex: 1; margin: 0 1rem; padding: 1rem; background: #fff; border-radius: 5px; text-align: center; } .feature h2 { margin-bottom: 1rem; font-size: 1.5rem; } .feature p { font-size: 1rem; } /* Footer Styles */ footer { background: #333; color: #fff; text-align: center; padding: 1rem 0; } ``` ### Component CSS Files To keep your styles modular and maintainable, break down the main CSS file into component-specific files. This example includes styles for the header, footer, and main content. **Header CSS (components/header.css)**: ```css header { background: #333; color: #fff; padding: 1rem 0; text-align: center; } header .logo img { max-width: 100px; } header nav ul { display: flex; justify-content: center; list-style: none; padding: 0; } header nav ul li { margin: 0 1rem; } header nav ul li a { color: #fff; text-decoration: none; font-weight: bold; } ``` **Footer CSS (components/footer.css)**: ```css footer { background: #333; color: #fff; text-align: center; padding: 1rem 0; } ``` **Main Content CSS (components/main-content.css)**: ```css /* Hero Section */ .hero { background: #fff; padding: 2rem; text-align: center; } .hero h1 { margin-bottom: 1rem; font-size: 2.5rem; } .hero p { font-size: 1.2rem; } /* Features Section */ .features { display: flex; justify-content: space-around; padding: 2rem; background: #e9e9e9; } .feature { flex: 1; margin: 0 1rem; padding: 1rem; background: #fff; border-radius: 5px; text-align: center; } .feature h2 { margin-bottom: 1rem; font-size: 1.5rem; } .feature p { font-size: 1rem; } ``` ### Combining CSS Files To combine these component-specific CSS files into a single main CSS file, you can use a CSS preprocessor like SASS or simply import them into `main.css` using the `@import` rule. **Updated Main CSS (main.css)**: ```css @import url('components/header.css'); @import url('components/footer.css'); @import url('components/main-content.css'); /* Global Styles */ body { font-family: Arial, sans-serif; line-height: 1.6; margin: 0; padding: 0; background-color: #f4f4f4; color: #333; } ``` ### Web-Safe Fonts and Colors **Web-Safe Fonts**: Use fonts that are widely available on most systems to ensure consistency: - Arial - Verdana - Georgia - Times New Roman - Courier New - Tahoma **Web-Safe Colors**: Stick to standard color names or hexadecimal values: - White: `#ffffff` - Black: `#000000` - Gray: `#808080` - Red: `#ff0000` - Blue: `#0000ff` - Green: `#008000` ### Accessibility Considerations 1. **Semantic HTML**: Use proper HTML elements (`

`, `

`) to give structure and meaning to your content. 2. **ARIA Attributes**: Enhance accessibility with ARIA (Accessible Rich Internet Applications) attributes where necessary. 3. **Alt Text for Images**: Always provide meaningful `alt` attributes for images. 4. **Keyboard Navigation**: Ensure that your site can be navigated using a keyboard. 5. **Color Contrast**: Make sure there is sufficient contrast between text and background colors for readability. ### Summary 1. **Organize Files**: Use a clear and maintainable project structure with separate folders for CSS, images, and JavaScript. 2. **Boilerplate HTML**: Create a basic HTML file with semantic structure and minimal content, with accessibility in mind. 3. **Modular CSS**: Split CSS into component-specific files for easier management and scalability. 4. **Combine CSS**: Use `@import` or a CSS preprocessor to combine component-specific CSS files into a main CSS file. 5. **Web-Safe Items**: Use web-safe fonts and colors for consistency across different systems and browsers. 6. **Accessibility**: Implement accessibility best practices to make your site usable for everyone. By following this structured approach, you can build and maintain HTML and CSS projects that are well-organized, scalable, and accessible. This will align with standard web development practices and help you learn CSS effectively. --- ### Accessibility Considerations #### Semantic HTML **Use Proper HTML Elements**: Use semantic HTML elements like `

`, `

`, and `

` to give structure and meaning to your content. This improves accessibility by helping assistive technologies understand the structure of your webpage. - **Header**: Wrap the introductory content or navigational links for the webpage. ```html

Website Title

``` - **Nav**: Use the `

` element for the navigation section. ```html ``` - **Main**: Enclose the main content of the document. ```html

``` - **Footer**: Wrap the footer content. ```html ``` ### ARIA Attributes **Enhance Accessibility with ARIA (Accessible Rich Internet Applications) Attributes**: - **aria-label**: Provides an accessible name to an element. ```html Home ``` - **aria-hidden**: Indicates whether an element is visible to screen readers. ```html ``` - **aria-live**: Announce dynamic changes in content to screen readers. ```html

New content loaded dynamically.

``` ### Alt Text for Images **Always Provide Meaningful `alt` Attributes for Images**: - **Informative Image**: Describe the content of the image. ```html

``` - **Decorative Image**: Use an empty `alt` attribute for decorative images. ```html

``` ### Keyboard Navigation **Ensure that Your Site Can Be Navigated Using a Keyboard**: - **Focus Order**: Ensure a logical focus order for interactive elements. ```html Skip to main content ``` - **Focus Styles**: Provide visible focus indicators for interactive elements. ```css a:focus { outline: 2px solid #000; } ``` ### Color Contrast **Ensure Sufficient Contrast Between Text and Background Colors for Readability**: - **WCAG Guidelines**: Follow the Web Content Accessibility Guidelines (WCAG) for color contrast (e.g., 4.5:1 for normal text, 3:1 for large text). ```css body { color: #333; background-color: #f4f4f4; } ``` ### Additional Best Practices 1. **Headings**: Use heading tags (`

`, `

`, etc.) appropriately to define the structure and hierarchy of your content. 2. Forms: Label form elements properly. ```html Email: ``` 3. Links: Ensure link text is descriptive and meaningful out of context. ```html Learn more about our services ``` 4. Tables: Use tables for tabular data, with appropriate headers. ```html

``` By integrating these accessibility considerations into your HTML and CSS, you ensure your website is usable and accessible to a wider audience, including people with disabilities. This aligns with best practices and standards in web development.
