A structural elements is any element that separates the content for section to section. The common forms of structure changes are contrasting color, dividing lines, even large text. Without structural elements a page will look the way the internet was when it started; straight text with images all one column, one solid background or repeating pattern.
In my site there are only 3 main color structures, 1 text structural element with the help of 1 divider. If you look up at the header of the page is the first section. It contains one of the focal points, my main links, and a mini bio. Then comes this section, where the main content is. This also where you’ll find the dividers and larger text, which is located in the Toolbox and Portfolio pages. Finally there’s the third color section the footer. In this section is the Featured, Calender, and Credits.
