Common problems found in HTML

Another issue that frustrates people is "white space".  Using multiple spaces between words and paragraphs will always be reduced to one space by all browsers.  So, if you hit the space bar multiple times to form a larger separation between words or paragraphs, you will be wasting your time.  Instead, include the character code " " for each space that you need for the separation between words or paragraphs.  You will find that the " " character is not as wide as the space created by the space bar and that you will need to add more of the characters to get the separation that you desire when using multiple spaces.  One other thing on this issue is that we normally hit the space bar twice after each sentence before beginning a new sentence.  Browsers ignore the second space and the page view will only see one space between sentences.  To correct this problem, use the " " character with one space bar space and you will see the normal two spaces when viewing the sentences on the page as in these paragraphs.  The browser companies don't intend to change this issue in the near future since it can also be resolved with the "margin" and "padding" elements in your code.
