Multiple choice javascript

How do you put a message in the browser's status bar?

  1. window.status = "put your message here"

Multiple choice javascript

Which property would you use to redirect visitor to another page?

  1. window.location.href

  2. document.href

  3. java.redirect.url

  4. link.redirect.href
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To redirect a visitor to another page using JavaScript, you can use the window.location.href property. This property sets or returns the entire URL of the current page, including the protocol, host name, path, and the file name of the current page. By assigning a new URL to this property, you can redirect the user to a new page.

Option A is correct: window.location.href

Option B is incorrect because there's no document.href property.

Option C is incorrect because there's no java.redirect.url property.

Option D is incorrect because there's no link.redirect.href property.

Therefore, the correct answer is:

The Answer is: A

  1. this is a good practice

  2. this is REQUIRED

  3. this ensures browser compatibility

  4. this ensures OS compatibility
Reveal answer Fill a bubble to check yourself

Multiple choice web-design

Which of the following is NOT true of navigation?

  1. A good navigation plan should include shortcuts.

  2. Common navigational schemes include the items: FAQ, Search, About, and Site Map.

  3. The visitor should not have to click more than 3 times to reach a desired page.

  4. Icons and logos should be avoided in navigational structures because graphic files increase download times.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The question asks what is NOT true - option D claims icons should be avoided due to download time, which is outdated thinking. Modern web design embraces icons for visual communication and improved UX. Options A, B, and C describe legitimate navigation best practices: shortcuts are useful, FAQ/About/SiteMap are standard elements, and the '3-click rule' is a common (though debated) heuristic.

Multiple choice css html

In what form are style rules presented?

  1. selector { property: value }

  2. selector { property= value }

  3. selector ( property: value )

  4. selector ( property= value )
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

CSS style rules follow the syntax 'selector { property: value }' where the selector targets HTML elements, properties and values are separated by a colon (not equals sign), and the declaration block uses curly braces { }. Options B and D incorrectly use '=' instead of ':'. Options C and D use parentheses instead of curly braces, which is incorrect CSS syntax.
