Website Coding
Website Review of lenntech.com
It was difficult to think of a website that uses a table for its data, so I am going to review a website I use to reference what element name corresponds with what abbreviation. This website does have many other uses, but I am just going to review this part since it contains a table. The website itself is pretty simply laid out with navigation along the left and the top, and the rest is just the information of the page. There are four columns in the table: one that allows you to choose how you would like the rest of the table to be sorted (symbol, density, etc.), one that shows the symbol of the element, one that gives the element name, and one that gives the atomic number of the element. If the table is sorted by something that relates to the elements in some other way besides the default information (for example, density), an extra column is added to show the density of each element, but the default sort, which is by symbol, just gives the columns mentioned above. In addition, clicking on an element name will bring you to a different part of the website which tells you specifically about the selected element.
As for the design of the table itself, it is pretty simple. There was some CSS used but not a lot. The headers of the columns are bolded, but they are not centered. Also, the element symbols are bolded since these are probably the most important thing to know about an element. Besides this, the only other design aspect I see is the border which appears 3-D on the page. Something worth mentioning though is the fact that clicking on some of the sort functions removes the borders altogether, and the content is pushed close together on the right side of the page.
Validation produced something very interesting. I validated the page with the table when it was sorted by symbol, and it produced a list of 1001 errors with the last one being a fatal error saying there are too many messages, so I assume there are a lot more errors that are not even displayed on the validation website.
