Audience Shout Out Rounds

Shoutout Block 1

Given the following CSS and HTML, what will the web site show?

<style>
    body { color: black; }
    p { color: blue; display: inline }
</style>

<p>Hello <p style="color: green">green</p> World</p>

• A blue text “Hello green world” with the word green in green
• Styles in the body are invalid, nothing will be shown
• Hello green world in black
• “Hello green world” in the colours blue, green and black (correct answer)

Solution: You can’t nest p elements, that’s why the blue isn’t applied to the last Word.

    getValue() { return this.value; }
};
console.log(calculator.add(5).pow(3).getValue())
