Is it better to use upper case, lower case or mixed case letters for HTML4.01 coding?
Although HTML4.01 allows you to use upper case, lower case or mixed case letters in coding, I strongly suggest that you get in the habit of using all lower case for coding. When you get into more advanced & current forms of coding, it will be required, so starting that habit now so the transition will be easier. You will not be corrected for using upper case or mixed coding in this class, but I hope you will try to develop the better habit of all lower case coding at this point. Bad or outdated habits can be hard to break later when they are ingrained in your mind.
