Studied a bit about CSS Box Model. Each element can be classified to inline elements and block level elements. It is good to use only inline elements in <p> element.

Changed the design of css_usages.html and tag_usages.html by applying what I learned recently. h1~h4 tags now has their own distinct color on its left-side borders to indicate the hierarchy more clearly.

About to finish learning about CSS Box Model. Block elements have content-box at center, surrounded with padding, border, margin box in given order.

Each box (content, padding, border, margin) has its own unique properties to render them.

You can also set background for elements. Gradation is another choice.

Meanwhile, Applied CSS to css_usages.html. Layout and Design have been improved.
