A few weeks ago I wrote about the Traditional Box Model and the ‘box-sizing’ CSS property, which, in essence, allowed you to easily create two adjacent boxes with a width of 50% and any amount of padding, because padding was included in the width. In this article I will talk about a different method of achieving this with the help of the ‘calc()’ expression.
One of the first things you come to learn about when first introduced to CSS is the box model. It works on the condition that every element within HTML is square and the box model defines how each element is then subsequently defined in terms of width and height. Although not explicitly mentioned, it was introduced in 1996 with the CSS1 specification (those were they days ‘ey?).
Columns are lovely things. They allow you to read text easier, make chunks of text look nicer and now with the power and beauty of CSS3 you can make columns dynamically – yey! No more table columns and splitting of paragraphs to achieve the same effect.
