When it comes to building layouts and positioning content on a page there are a handful of different techniques to use. Which technique to use largely depends on the content and the goals of the page, as some techniques may be better than others. For example, the ability to float elements side by side provides a nice, clean layout that is receptive to the different elements on a page.
The float CSS property places an element on the left or right side of its container, allowing text and inline elements to wrap around it. The element is removed from the normal flow of the page, though still remaining a part of the flow in contrast to absolute positioning. The source for this interactive example is stored in a GitHub repository.
In this chapter, we'll take a look at how the various CSS layout properties can be used to influence the sizing, positioning and overall layout of a page. I have also included a number of puzzles to help you review the things you have learned in the previous chapters. This chapter is organized by use case rather than by property or feature.
CSS allows to release the elements of the normal flow of the document and position them at will with absolute, relative, fixed and floating properties. The block elements always generate a new line and are ordered one below the other, the inline elements do not generate a new line and they are ordered side by side. CSS also offers us the possibility of releasing the elements of the normal flow of the document and accommodating them at will.
What I do is this:. My problem is this: I feel this margin solution is a somewhat inelegant and convoluted one. Put your three divs inside another div that is the same height as the smaller divs and three times the width of the sum of the smaller divs.
Given the following markup, we might be told to have main and sidebar side by side and the contact section appear in the sidebar but all the way down. First, for our main and sidebar divs to stand by side by side, we can simply float them:. The trick is now to create a positioning context of content div in which we can position contact absolutely.
In the visual formatting model, each element in the document tree generates zero or more boxes according to the box model. The layout of these boxes is governed by:. The properties defined in this chapter and the next apply to both continuous media and paged media. However, the meanings of the margin properties vary when applied to paged media see the page model for details.
Layout is the operation of positioning and styling elements of content in a given space. It aims to position the content text, images, notes… in a hierarchical and harmonious way balancing the zones, colors and spaces, contrastsin order to facilitate display and the flow of reading. Layout is more complex than the flow of content from one page to the next with appropriate elements of stylization.
