Professional CSS3

Chapter 2. Mastering of Fundamentals

This chapter will master the box model, floating troubleshooting positioning, and display types. After this chapter, you will be more aware of the foundations of HTML and CSS.

In this chapter, we will cover the following topics:

  • Gaining knowledge about the traditional box model
  • Basics of floating elements
  • Foundations of positioning elements on a web page
  • Gaining knowledge about display types

Traditional box model

An understanding of the box model is the foundation of CSS theories. You have to know the impact of width, height, margin, and borders on the size of the box and how you can manage it to match the elements on a website. The main questions for coders and frontend developers in interviews are based on box model theories. Let's begin this important chapter, which will be the foundation for every upcoming subject.

Padding/margin/border/width/height

The ingredients of the final width and height of the box are as follows:

  • Width
  • Height
  • Margins
  • Paddings
  • Borders

For better understanding of the box model, the following is an image from Google Chrome inspector:

Padding/margin/border/width/height

For more clarity and better understanding of the box model, let's analyze the following image:

Padding/margin/border/width/height

In the preceding image, you can see that in the box model, we have the following four edges:

  • Content edge
  • Padding edge
  • Border edge
  • Margin edge

The width and height of the box are based on the following:

  • Width/height of content
  • Padding...

Floating elements

Floating boxes are the most used in modern layouts. The theory of floating boxes was used especially in grid systems and inline lists in CSS frameworks. For example, class and mixin inline lists (in the Zurb Foundation framework) are based on floats.

Possibilities of floating elements

Elements can be floated to the left and right side. Of course, there is a method to reset floats too. The possible values are as follows:

float: left; // will float element to left
float: right; // will float element to right
float: none; // will reset float 

Most known floating problems

When you are using floating elements, you can have some issues. The most known problems with floated elements are as follows:

  • Too big elements (because of width, margin left/right, padding left/right, and badly counted width, which is based on the box model)
  • Not cleared floats

All of these problems provide specific effects, which you can easily recognize and then fix.

Elements which are too big can be recognized when...

Display types

There are a few display types in CSS whose definition and behaviors are the foundation of frontend developers. The most known and basic display values are as follows:

  • Inline
  • Block
  • Inline-block
  • Table/table-cell
  • Flex (this will be described further in this book)

Block elements

Block elements always start from a new line. The most important properties of block elements are width and height, which can be changed from CSS code. For better understanding, let's check the following screenshot:

Block elements

It is easy to see that all the block elements are taking as much width as they can.

The mainly used HTML block-level elements are as follows:

  • address
  • article
  • aside
  • blockquote
  • canvas
  • div
  • footer
  • form
  • h1, h2, h3, h4, h5, h6
  • header
  • main
  • nav
  • ol
  • output
  • p
  • pre
  • section
  • table
  • ul
  • video

Inline elements

Inline elements can be described as elements that take as much space as they need. It can be best described using the following image:

Inline elements

The mainly used HTML inline-level elements are as follows:

  • acronym
  • cite
  • code
  • dfn
  • strong
  • samp
  • var
  • a
  • bdo
  • br
  • img...

CSS elements positioning

Understanding of positions in CSS is one of the key skills of frontend developers. It helps you to change the behavior of each element on a web page. Additionally, with a mix of positions, you can change the behavior of the inner (child) elements.

Static, relative, absolute, fixed – differences

The position static is a default value of the position, which includes every element on a web page.

The position relative is making an element relative to itself. You can easily understand it with the following code:

<p>
    Lorem
    <span> ipsum</span>
</p>

And create the SASS:

span
  position: relative
  top: -10px

What you should see before appending the styles is as shown in the following:

Static, relative, absolute, fixed – differences

In addition, after appending the styles you will see the following:

Static, relative, absolute, fixed – differences

As you can see, when we change the position to relative and move it with property top, left, right, or bottom, we will move the element from its current position.

Additionally, relatively positioned...

Summary

This chapter builds strong fundamentals for professional usage of CSS. You gathered the knowledge about the box model, positions, and floating elements. The next chapter is going to be a story about pseudoclasses.

I might have chose the wrong book as it doesn't reflect what I was looking for. This book is good if you need an overview about the CSS potential and the solid/basic in the case you intend to create your own framework. However, it doesn't help with proper html stilying nor provides a guide to enhance your element look&feel (forms,inputs,etc etc) for nowadays UI. I was definitely expecting something different and more content related to how to style an html component in order to have a decent and modern UI.

Just an awful book. Essentially unstructured documentation with edge case tricks. I regretfully dragged my team through the first few chapters before dropping it for good. Filled with edge case examples with minimum explanation. For example, flex shorthand format is used in an example with zero explanation and before any mention of flex longhand format (flex-grow, flex-shrink, etc.).
