Part of the ePortfolio requirements for this course includes submitting at least two examples of homework assignments in order to demonstrate our proficiencies with HTML, CSS, and JavaScript. This website itself - entirely hand-coded using HTML, CSS, and PHP - serves as demonstration of the first two criteria.
The exercise embedded below serves to demonstrate my proficiency using JavaScript. It is also the ONLY JavaScript to be found anywhere in this site! JavaScript has numerous security issues - so many that many browsers disable JavaScript by default - so I personally avoid using it if at all possible.
