I need some help with HTML and JS

• Using the onmouseover event handler and JavaScript
  • Make the first heading have red text and become 42pt in size when the third heading is moused over.
• When the fourth heading is clicked
  • change its content to read,This is a fun Valentine!
• Use onmouseover in the fifth heading
• to do something neat to both the fifth and sixth headings
  • and use onmouseout to set them back to how they were.

• When you mouse over the seventh heading
  • change the first heading to read, So glad you are here followed by the first name that the user entered in the first prompt box.

Hint: you will concatenate the value of the variable used to store the first name with the message. Variable names are not enclosed in quotes we want the value of the variable, not the name of the variable to appear.
