Dear Colleague, Earlier today I built my seventh website using HTML5, CSS3, and Bootstrap4. Bootstrap seems amazing, but it never did what it should do – make my website look better. Also, my page should have a blue theme that was provided in the CSS folder. This also didn’t work. My website is supposed to look like what is shown in Figure 1 (see below). Someone told me that there are exactly 10 errors on index.html, 10 errors on contact.html, and 10 errors on events.html. Yes, 30 errors total! Can you help me find all of the errors? Hint: You should not add ANY LINES to the code. There will never be more than one error per line number.

events.html ( HELP FIND the 10 ERRORS IN THIS CODE )

Task 1: HTML and CSS Create a website using HTML5 and CSS3 only.
