17. Give me an example of a site that is a good resource for scientific information.

[apod.gsfc.nasa.gov] This is the URL for one of my favorite astronomy sites: "Astronomy Picture of the Day" which is part of the NASA web site. I have learned so much about astronomy, meteorology and other sciences from this web site.

1. Why is it better to use iframes than using frames?

Web pages using frames are really several different html documents that come together to create one "web page." The frame tag replaces the body tag on the html document. Because of this, each html document must be coded separately, which can take a long time and a lot of typing, making it an arduous task to maintain. In addition, because the page involves the use of several different documents, this means each one of them needs to be loaded separately which can lengthen the time needed to load the page. This extra time to load the page could be the difference between when a user chooses to wait for the page to load or decides that it is not worth waiting and navigates away from your page.

On the other hand, iframes consist of one frame that is embedded onto a single web page. This offers the advantages of frames, which include a consistent look throughout a web site without the disadvantages of frames. Instead of having to code several different html documents to make the appearance of one page, there is one iframe that interchanges with another to give the appearance of moving to another page while the background remains the same. Another advantage is that for iframes the browser only has to look for one html document and loads it much the same as if it were loading an image. This means quicker load times than frames. Also, using frames, the user can resize an individual frame thereby altering the look of the page. This is not the case with iframes, giving the web developer a little more control in the presentation of the page.

12. Tell us in detail how you create a table in Dream Weaver?

Once you have your page open (or have a new HTML page created), you put your cursor in the spot where you want to put your table. Then you click on the "insert" button, then click on table. This brings up a box which allows you to add rows and columns, set your table width, put in a border, and cell padding and spacing. Once you set these (which can be changed later), click OK.

Once you have your table added, you can select your table and the properties will be displayed at the bottom of the screen. You can change your table here, align it, add background or border colors, etc.

You can also select a row or a column and merge the cells in the properties area on the bottom left of the screen. You can chage the width or height of a row or column by just dragging that area of the table over with the mouse.

13. Give us an example of why you might want to start a table other than one.

Is this a typo? :)

Note from Dan: It should say, start a table numbering from a value other than one.

I assume that is actually a list starting with a number other than 1.

<ol start="7">

<li>seven</li>
<li>eight</li>
<li>nine</li>

</ol>

Will give you

7. seven
8. eight
9. nine

14. Give us an example of why you might want to override an unordered list bullet.

While using HTML and CSS to construct an unordered list you only have three choices of bullets; square, circle, and disc. While they look fine, one may wish to use a small graphic that is more fitting with the page structure. For the custom bullet one only needs to include this CSS code.

list-style:url(file-location)

file-location being the absolute or relative url of the picture that you want to use.

Personal edit:

you should probably use this css code, though the above works.

list-style-image:url(file-location)

2. Why are frames becoming less popular?
Frames require additional web pages and a frameset cannot be changed once it is in use. iframes can be deleted or created as the need arises without requiring a re-design of the entire web site.

18. Find a scientific site that uses tables or lists to present information.
CERN (http://public.web.cern.ch/Public/Welcome.html) uses tables throughout their website. MIT (http://www.mit.edu/) uses tables, lists and divs; many of the pages uses lists and divs instead of tables.

4. Give us an example of a good use of definition lists. If in your web site like the one we are creating for the class you have words that most people don't know the meanings for, or in our case the English translation for. You would use a definition list to explain to the people looking at your web site what the words mean in English.
14. Give us an example of why you might want to override an unordered list bullet. You might want to override the bullet if you have a graphic that would work well with your web site and that would not take away from what you are trying to say.

-If you would want to change the bullets to an image of your choice.

The lays out the advantages and disadvantages in a pretty straightforward way.
