Question: What are HTML forms, and how do you create them?

Question: Can you explain the difference between '<strong>' and '<b>' tags in HTML?
|
Answer: Both '<strong>' and '<b>' tags are used to apply bold formatting to text.
However, '<strong>' is a semantic tag indicating that the enclosed text is of strong importance,
while '<b>' is presentational, used to apply bold styling without conveying additional semantic meaning.
It's recommended to use '<strong>' for emphasis on important content and '<b>' for purely stylistic purposes.

Question: Can you explain what is an '<iframe>' tag in HTML?
|
Answer: The '<iframe>' tag is used to embed another HTML document within the current document.
It is commonly used for displaying content from external sources such as maps, videos, or advertisements.
However, '<iframe>' can also be a security risk if not used carefully, as it can be exploited
for cross-site scripting (XSS) attacks or clickjacking. It's important to ensure that the content
inside the '<iframe>' is from a trusted source and that appropriate security measures are in place.

Question: Can you explain the concept of HTML entities?
|
Answer: HTML entities are special codes used to represent characters that have special meanings in HTML,
such as '<', '>', &, and non-breaking space.
For example:
• '<' represents '<'
• '>' represents '>'
• '&' represents '&'
• ' ' represents a non-breaking space.
Using HTML entities ensures that special characters are displayed correctly
in web browsers and avoids potential parsing errors.

Question: What is the purpose of the 'placeholder' attribute in HTML form elements?
|
Answer: The 'placeholder' attribute is used to provide a hint or example text within
an input field to indicate the expected format or value.
It is typically used for input fields where the expected value is not immediately obvious.
For example, '<input type="text" placeholder="Enter your email">' displays the text
"Enter your email" inside the text input field until the user starts typing.
