Q & A

What is the purpose of the h1 tag in HTML?

The h1 tag in HTML is used to define the most important heading on a webpage, typically the main title of the page.

What causes confusion between HTML and CSS when mixed together?

Confusion arises when HTML and CSS are mixed because the browser has to determine whether a line of code is HTML or CSS, which can lead to styling issues.

How can browser confusion between HTML and CSS be resolved?

Browser confusion can be resolved by ensuring that CSS code is always placed between opening and closing style tags, which helps the browser understand that the code within is CSS and not HTML.

What is the role of the style tag in HTML?

The style tag in HTML is used to embed CSS directly into an HTML document, allowing for the styling of the webpage without the need for external stylesheets.

Why is it important to keep the content of the style tag separate from the content of the HTML?

It's important to keep the content of the style tag separate from HTML because the style tag's content is not displayed on the webpage, whereas HTML content is meant to be displayed and read by users.

What is the syntax for writing CSS rules?

The syntax for writing CSS rules involves a selector, followed by an opening curly brace, the declaration block with properties and values, and then a closing curly brace.

How can you change the color of a paragraph in CSS?

You can change the color of a paragraph in CSS by using the color property within a rule set that targets the paragraph element, like so: p { color: green; }.

What does the 'font-size' property in CSS do?

The 'font-size' property in CSS is used to set the size of the font, which determines the size of the letters displayed on the webpage.

Why might a heading not display the desired color even after setting it in CSS?

A heading might not display the desired color if there are conflicting CSS rules or if the CSS is not properly linked to the HTML document, or if the browser cache needs to be cleared.

How can you create a heading size in CSS that is not available in HTML?

You can create a custom heading size in CSS by using the 'font-size' property and specifying a value that is not one of the standard HTML heading sizes.

Why might an additional h1 element not be displayed as expected?

An additional h1 element might not be displayed as expected if there is a CSS rule that is not correctly targeting it, or if there is a syntax error in the CSS that needs to be corrected.
