At the risk of over-repeating myself: every element in web design is a rectangular box. This was my What we haven’t talked about much is the box itself. How is the size of the box calculated exactly? Here is a diagram: If you are a Firebug user, you might be used to the diagram like this, which does a nice job of showing you the numbers affecting any box on the page: Notice in both examples the margin is in the white. Margin is unique in that it doesn’t affect the size of the box itself per se, but it affects other content interacting with the box, and thus an important part of the CSS box model. The size of the box itself is calculated like this: Width width + padding-left + padding-right + border-left + border-right Height height + padding-top + padding-bottom + border-top + border-bottom What if these values are undeclared? If padding or borders are undeclared, they are either zero (likely if you are using a not zero especially on form elements that are commonly not reset). If the width of a box is undeclared (and the box is a block level element), things get a little weirder. Let’s start with that, and then move on to some other good-to-know stuff about the box model. The Default Width of Block Level Boxes If you don’t declare a width, and the box has static or relative positioning, the width will remain 100% in width and the padding and border will push inwards instead of outward. But if you explicitly set the width of the box to be 100%, the padding will push the box...

If you're learning web development, you might have come across a concept called the Box Model in CSS. In this blog post, we'll dive into what the Box Model is, why it's important, and how you can use it effectively to create beautiful and responsive web designs. We'll explain everything in an easy-to-understand manner, with simple code examples and helpful analogies to make sure you grasp the concept. So, let's get started! What is the Box Model? In the world of web design, every element on a webpage can be thought of as a rectangular box. This might seem a bit strange at first, but it's a really powerful way to think about how elements are displayed on the screen. The Box Model is a set of rules that dictate how the dimensions, padding, borders, and margins of these boxes should be calculated and rendered. By understanding and using these rules, you can control the layout and positioning of elements on your webpage with precision. Let's break down the components of the Box Model one by one: Content: This is the actual text, images, or other media that make up the element. The dimensions of the content (width and height) can be set using CSS properties like width and height. Padding: This is the space between the content and the border of the box. You can think of padding as a cushion that surrounds the content, giving it some breathing room. Padding can be set using the CSS property padding, or by specifying individual values for each side with properties like padding-top...

CSS Box Model In this tutorial you will learn how elements are visually laid out on the web pages. What is Box Model? Every element that can be displayed on a web page is comprised of one or more rectangular boxes. CSS box model typically describes how these rectangular boxes are laid out on a web page. These boxes can have different properties and can interact with each other in different ways, but every box has a content area and optional surrounding padding, border, and margin areas. The following diagram demonstrates how the width, height, padding, border, and margin CSS properties determines how much space an element can take on a web page. Padding is the transparent space between the element's content and its border (or edge of the box, if it has no border), whereas margin is the transparent space around the border. Also, if an element has the Width and Height of the Elements Usually when you set the width and height of an element using the CSS width and height properties, in reality you are only setting the width and height of the content area of that element. The actual width and height of the element's box depends on the several factors. The actual space that an element's box might take on a web page is calculated like this: Box Size CSS Properties TotalWidth width + padding-left + padding-right + border-left + border-right + margin-left + margin-right TotalHeight height + padding-top + padding-bottom + border-top + border-bottom + margin-top + margin-bottom You w...

CSS boxes are the building blocks of any web page styled with CSS. Making them nice looking is both fun and challenging. It's fun because it's all about turning a design idea into working code; it's challenging because of the constraints of CSS. Let's do some fancy boxes. Before we start getting into the practical side of it, make sure you are familiar with On the technical side, Creating fancy boxes are all about mastering CSS border and background properties and how to apply them to a given box. But beyond the technics it's also all about unleashing your creativity. It will not be done in one day, and some web developers spend their whole life having fun with it. We are about to see many examples, but we will always work on the most simple piece of HTML possible, a simple element: Hi! I want to be fancy. Ok, that's a very small bit of HTML, what can we tweak on that element? All the following: • Its box model properties: width, height, padding, border, etc. • Its background properties: background, background-color, background-image, background-position, background-size, etc. • Its pseudo-element: ::before and ::after • and some aside properties like: box-shadow, rotate, outline, etc. So we have a very large playground. Let the fun begin. .fancy Yes, we get a circle: When we talk about a fancy box, the core properties to handle that are Before we jump to some practical examples, let's step back a bit as there are two things you should know about backgrounds. • It's poss...
