Ch 7 More on HTML5

Introduction

Welcome back, budding web designers! In this post, we’re diving into HTML5, a powerful language that forms the backbone of the web. Chapter 7 of our “Touchpad” book introduces some advanced HTML5 tags that help us design more structured, interactive, and visually appealing websites. Let’s explore the key tags, their uses, and how they can help us create rich web experiences.

1. HTML Text Properties

HTML text properties control how text appears on the webpage. This includes properties like:

  • text-align: Aligns text to the left, right, center, or justifies it within its container.
  • text-indent: Indents the first line of text within a paragraph.
  • text-decoration: Adds decoration to text, such as underline, overline, or strikethrough.

These properties allow us to create readable, well-organized content that enhances the user experience.

2. Font Properties

Font properties in CSS help us change the appearance of text by specifying:

  • font-family: Sets the typeface (e.g., Arial, Times New Roman).
  • font-size: Adjusts the size of the text.
  • font-style: Controls the style, such as normal, italic, or oblique.
  • font-weight: Sets the thickness of text, like bold or light.

By using font properties, we can give the webpage a unique style and ensure text remains readable.

3. HTML Tags and Attributes

HTML tags form the structure of a webpage, while attributes add extra information to these tags. For example:

  • <header>, <footer>, <section>, <article>: Tags that create a structured, semantic layout for the webpage.
  • id and class: Attributes used to uniquely identify elements or group them for styling with CSS.
  • style: Inline attribute to add quick styling to individual elements.

These tags and attributes make our code organized and improve the overall structure of our website, which is beneficial for both users and search engines.

4. Background Properties

Background properties allow us to enhance the look of a webpage by adding colors or images. Some useful background properties include:

  • background-color: Sets a color as the background of an element.
  • background-image: Adds an image as the background.
  • background-repeat: Controls whether the background image repeats or not.
  • background-position: Sets the position of the background image.

These properties can be combined to create visually appealing designs that make the webpage stand out.

5. Margin Properties

Margins create space outside of an element’s borders. Margin properties help control spacing around elements, making the layout neat and aesthetically pleasing. Some examples include:

  • margin-top, margin-right, margin-bottom, and margin-left: Set specific margins for each side of an element.
  • margin: Shorthand property to set all four sides at once.

Using margins helps in positioning elements on the webpage and gives each section or component a clear, organized look.

    c. Which tag will be frequently used to write algebraic formulas?

    Long Answer Type Questions:

    a. Explain the use of horizontal ruler tag and its various attributes.
    Answer:
    The <hr> (horizontal ruler) tag is used in HTML to create a horizontal line that visually separates content. It can be styled with various CSS properties:

    • color: Sets the color of the line.
    • width: Controls the width of the horizontal line.
    • size or height: Sets the thickness of the line.
    • align: Aligns the line to the left, right, or center (although this is deprecated in HTML5, it can be done with CSS).

    b. Explain the uses of the font property in detail.
    Answer:
    The font property in CSS is a shorthand for setting multiple font-related properties in one go. It can include:

    • font-style: Determines the style of the font, such as normal, italic, or oblique.
    • font-variant: Controls whether the text is displayed in small-caps.
    • font-weight: Sets the weight (thickness) of the font, such as bold or normal.
    • font-size: Determines the size of the text.
    • font-family: Specifies the font family, like Arial, Times New Roman, etc.

    Combining these properties allows you to style text efficiently.

    c. Distinguish between:

    (i) <sub> and <sup> tags

    • <sub> (Subscript): The <sub> tag is used to display text slightly below the regular line, often used for chemical formulas or mathematical indices (e.g., H₂O).
    • <sup> (Superscript): The <sup> tag displays text slightly above the regular line, commonly used for exponents or ordinal indicators (e.g., x²).

    (ii) text-align and text-indent

    • text-align: This CSS property aligns text within a container. It can be set to values like left, right, center, or justify.
    • text-indent: This CSS property indents the first line of text within a block. It’s typically used to create paragraph indentation, measured in units like px, em, or %.

Tech Practice: Create the following web page in HTML5.

  • Title: Web Page on Environment
  • Body Content:
    • Heading: “Web Page on Environment” (Bold, Centered, and Underlined)
    • Paragraph text: “Environment is everything that is around us. It can be living (biotic) or non-living (abiotic) things. It includes physical, chemical, and other natural forces.”
    • Footer: “This web page has been created by [your name]”
