Questions and Answers
- 1.
Does setting margin-top and margin-bottom have an affect on an inline element?
- A.
NO
- B.
YES
Correct Answer
A. NOExplanation
Setting margin-top and margin-bottom does not have an effect on an inline element because inline elements do not have a width or height, and they are not affected by vertical margins. Inline elements are typically used for small pieces of content within a larger block-level element, and their layout is determined by the surrounding text and other inline elements. Margins can only be applied to block-level elements, which have a defined width and height and can be positioned and spaced using margins.Rate this question:

Does setting padding-top and padding-bottom on an inline element add to its dimensions?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Setting padding-top and padding-bottom on an inline element does not add to its dimensions. Padding only affects the space within the element, not its overall size. Inline elements are typically only as wide as their content, and adding padding does not change this. The padding will create space within the element, but it will not increase the width or height of the element itself.Rate this question:

If you have a <p> element with font-size: 10rem, will the text be responsive when the user resizes / drags the browser window?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When the font-size property is set to 10rem, it means that the font size will be 10 times the size of the root element's font size. Since the root element's font size does not change when the user resizes or drags the browser window, the text will not be responsive. Therefore, the answer is false.Rate this question:

- A.
It will move 5px downwards
- B.
All elements succeeding #example with move 5px upwards
- C.
Neither
Correct Answer
B. All elements succeeding #example with move 5px upwardsExplanation
The CSS code "#example { margin-bottom: -5px; }" sets a negative margin-bottom value for the element with the id "example". This will cause the element to move 5px upwards, pulling all elements succeeding it along with it. Therefore, the correct answer is "All elements succeeding #example will move 5px upwards."Rate this question:

Using a <style> element in head section is known as
- A.
External
- B.
Outline
- C.
Internal
- D.
Inline
Correct Answer
C. InternalExplanation
Using a element in the head section of an HTML document is known as internal styling. This method allows for the inclusion of CSS rules directly within the HTML file, making it easier to maintain and apply consistent styles across multiple pages. Unlike inline styling, which applies styles directly to individual HTML elements, internal styling affects all elements within the document that match the specified CSS rules. External styling, on the other hand, involves linking an external CSS file to the HTML document.Rate this question:

In HTML elements, CSS can be added in different
- A.
2 ways
- B.
3 ways
- C.
4 ways
- D.
5 ways
Correct Answer
B. 3 waysExplanation
HTML elements can have CSS added to them in three different ways. The first way is by using inline CSS, where the CSS code is directly added to the HTML element using the "style" attribute. The second way is by using internal CSS, where the CSS code is placed within the tags in the head section of the HTML document. The third way is by using external CSS, where the CSS code is placed in a separate CSS file and linked to the HTML document using the tag. These three ways provide flexibility in adding and managing CSS styles to HTML elements.Rate this question:

If form data contains sensitive or personal information, method to use is
- A.
Post
- B.
Get
- C.
Set
- D.
Append
Correct Answer
A. PostExplanation
The correct answer is "Post" because the Post method is used to send data to the server in a secure and confidential manner. When sensitive or personal information is being transmitted, it is important to use the Post method as it sends the data in the body of the HTTP request, rather than in the URL like the Get method. This ensures that the data is not visible in the browser's address bar or in server logs, providing an extra layer of security.Rate this question:

Javascript is _________ language.
- A.
Programming
- B.
