All questions of DHTML & CS for Class 10 Exam

D

Answer:
The correct answer is B:
Explanation:
The units '% and 'em' allow the user to adjust the font size according to their preference. Here is a detailed explanation:
- %: The percentage unit allows the user to set the font size relative to the parent element. For example, a font size of 100% is the default size inherited from the parent element, while a font size of 200% would be twice as large.
- em: The em unit also allows the user to adjust the font size relative to the parent element. However, unlike the percentage unit, the em unit is relative to the current font size. For example, if the font size is 16px, 1em would be equivalent to 16px, while 2em would be equivalent to 32px.
In summary, both the '%' and 'em' units provide flexibility for adjusting font sizes based on the user's preference.

Font weight [font-weight] The property font-weight describes how bold or "heavy" a font should be presented. A font can either be normal or bold. Some browsers even support the use of numbers between 100-900 (in hundreds) to describe the weight of a font. p {font-family: arial, verdana, sans-serif;} td {font-family: arial, verdana, sans-serif; font-weight: bold;} 

Property for Text Spacing:
The correct property to give specified spacing between text characters is the "Letter Spacing" property.
Explanation:
The "Letter Spacing" property is used to control the spacing between individual characters in a piece of text. It allows you to increase or decrease the space between letters, giving you more control over the typography and visual appearance of the text.
Usage:
To apply letter spacing to text, you can use the CSS "letter-spacing" property. Here's how it works:
- Add the CSS property to the selector that targets the text you want to modify.
- Specify a value for the letter spacing. This value can be in pixels (px), ems (em), or other units.
Example:
```
p {
letter-spacing: 2px;
}
```
In the above example, the letter spacing for all paragraphs will be increased by 2 pixels.
Other CSS Properties:
The other properties mentioned in the options are not used for giving spacing between text characters:
A: Text Decoration: This property is used to add decorations to text, such as underline, overline, or line-through.
C: Text Transform: This property is used to change the capitalization of text, such as making it all uppercase or lowercase.
D: None of the above: None of the mentioned properties are used to give spacing between text characters.
In conclusion, the correct property to give specified spacing between text characters is the "Letter Spacing" property.

• CSS is a language used to control the presentation and layout of web pages.


• It is written in a separate file with a .css extension, which is then linked to the HTML document.


• CSS allows developers to define various styles for HTML elements, such as fonts, colors, spacing, and more.


• It provides a way to create consistent and visually appealing designs across multiple web pages.


• CSS follows a cascading order, meaning that styles can be inherited from parent elements and overridden by more specific styles.


• It supports various selectors to target specific HTML elements or groups of elements.


• With CSS, developers can create responsive designs that adapt and change based on different screen sizes and devices.


• CSS can be used in conjunction with other web technologies, such as JavaScript and HTML, to enhance the functionality and interactivity of web pages.

• Separation of concerns: CSS allows the separation of design and content, making it easier to maintain and update web pages.


• Consistency: CSS enables consistent styling across multiple web pages, providing a cohesive user experience.


• Efficiency: By using CSS, developers can apply styles to multiple elements simultaneously, reducing the amount of code and improving performance.


• Flexibility: CSS provides a wide range of styling options, allowing developers to create unique and customized designs.


• Accessibility: CSS supports accessibility features, making it easier to create web pages that are usable by individuals with disabilities.

In conclusion, Cascading Style Sheets (CSS) is a powerful language that allows developers to control the visual appearance and layout of web pages. It is an essential tool for creating attractive and responsive designs.

The Decorations or Effects that can be added to text are:
1. Text Align property:
- The Text Align property is used to specify the horizontal alignment of text within an element.
- It can be set to left, right, center, or justify.
- Left aligns the text to the left edge of the element.
- Right aligns the text to the right edge of the element.
- Center aligns the text in the center of the element.
- Justify aligns the text to both the left and right edges of the element, creating a straight edge on both sides.
2. Text Indent property:
- The Text Indent property is used to specify the indentation of the first line of text within an element.
- It can be set to a specific length or percentage value.
- A positive value indents the text to the right, while a negative value indents it to the left.
- This property is commonly used in paragraphs or lists to create an indentation for each new line or item.
3. Letter spacing property:
- The Letter spacing property is used to specify the space between characters in a text.
- It can be set to a specific length or percentage value.
- A positive value increases the space between characters, while a negative value decreases it.
- This property is often used for decorative or typographic purposes to create special effects or improve readability.
4. None of the above:
- This option indicates that none of the given options (Text Align property, Text Indent property, Letter spacing property) can be used to add decorations or effects to text.
- In this case, there may be other CSS properties or techniques that can be applied to achieve the desired effect.
By using these properties, you can enhance the appearance of text by aligning it, adding indentation, or adjusting the spacing between characters.
