Q1:Most Web pages I've seen on the Internet use <center> instead of <div align="center">. Should I be using <center> to make sure that my pages are compatible with older Web browsers?
A1: For maximum compatibility, you might prefer to use both the obsolete <center> tag and the new <div align="center"> tag, like this: <div align="center"><center>. This text will be centered in both old and new browsers. Don't forget to end the centered section with </center></div>.
Q2:I used <ul type="square">, but the bullets came out round, not square.
A2: Are you using Netscape Navigator 2 or higher or Microsoft IE 4 or higher? Alternative bullet types don't show up in any other Web browsers yet.
Q3:I've seen pages on the Internet that use three-dimensional little balls or other special graphics for bullets. How do they do that?
A3: That trick is a little bit beyond what this hour covers. You'll find out how to do it yourself at the end of Chapter 9, “Putting Graphics on a Web Page.”
Q4:How do I “full justify” text, so that both the left and right margins are flush?
A4: You don't. HTML 4 does not support full-justified text. You will be able to full justify text in the future using style sheets (see Hour 15), although that feature of the style sheet standard isn't supported by any current Web browser.
Q5:What languages have had Unicode assignments to their characters?
A5: Nearly all of them. In looking through the official Unicode handbook, you can even find a coding for the Cherokee and Canadian Aboriginal languages.
Q6:Is it possible for me to create my own entities?
A6: Yes, it is. You simply use the same syntax as the definitions in Figure 5.7.
