The content layer provides the raw data and structure of a web page using HTML. However, the content layer itself doesn't dictate the visual appearance. This is where the presentation layer comes in. The presentation layer, primarily using CSS (Cascading Style Sheets), is responsible for styling the content provided by the content layer.

CSS rules are used to control aspects like:

• Fonts: Specifying the font family, size, and color of text.
• Colors: Setting background colors, text colors, and border colors.
• Layout: Controlling the position and spacing of elements using techniques like floats, flexbox, and grid.
• Spacing: Adding margins and padding around elements.
• Visual Effects: Applying effects like shadows, gradients, and transformations.

Example: Consider an HTML paragraph. The content layer provides the text content. CSS can then be used to style that paragraph to have a specific font, color, and background. A CSS rule might look like this: p { font-family: Arial; color: blue; }. This rule would apply the specified styles to all paragraph elements on the page.

The browser receives the HTML from the content layer and the CSS from the presentation layer. It then applies the CSS rules to the HTML elements to render the final visual appearance of the web page. This separation of content and presentation allows for easy modification of the page's appearance without altering the underlying content.

Using relative file paths is essential for creating robust and portable web projects. Here's a breakdown of the reasons:

• Portability: Relative paths are relative to the location of the HTML file. This means the entire project can be moved to a different directory structure without needing to update every single stylesheet link. An absolute path, however, is fixed to a specific location and would break if the project's directory structure changes.
• Maintainability: When a project grows, the location of files might change. With relative paths, you only need to adjust the paths within the project's folder structure. Absolute paths require updating links throughout the entire website, which is time-consuming and prone to errors.
• Consistency: Relative paths ensure that stylesheets are always found relative to the HTML file, regardless of where the HTML file is located within the project. This promotes consistency and reduces the risk of broken links.

In summary, relative paths enhance the flexibility and ease of management of a web project.

The body section of the webpage should be structured using appropriate headings, subheadings, and paragraphs to present the plant information clearly and logically. A well-structured body section improves readability and user experience. Here's a suggested structure:

• Main Heading: "Plants Grown in the Community Garden" - This clearly states the purpose of the section.
• Subheadings for Plant Types: Each plant type (e.g., Tomatoes, Lavender, Roses) should have its own subheading. This allows users to quickly find information about specific plants.
• Paragraphs for Detailed Information: Within each plant type section, use paragraphs to provide details about:

• Care Requirements: (e.g., Watering frequency, sunlight needs, soil type). Use bullet points for a quick overview.
• Planting Instructions: (e.g., Depth, spacing).
• Potential Problems: (e.g., common pests or diseases).
• Benefits: (e.g., edible, ornamental, attracts pollinators).

• Images: Include relevant images of each plant type to enhance visual appeal and understanding. Alt text should be used for accessibility.

For example, a section on 'Tomatoes' might include a heading 'Tomatoes', followed by a paragraph detailing watering needs, sunlight requirements, and planting depth. A bulleted list could summarise the key care points. An image of a tomato plant would also be included.
