海外TECH	DEV Community	How the CSS Box Model Works	https://dev.to/smpnjn/css-box-model-37bl	How the CSS Box Model WorksThe CSS box model is a term thrown around in CSS with very little context but is probably the most fundamental things you can know in CSS Simply put the box model determines the size margin and padding of any object on the page It also refers to the weird way CSS handles inline and block content The Box ModelIn HTML every element creates a box Some of these elements such as span and p are inline meaning they are in line with text rather than structural elements of the page Other elements like div are large block elements Each element carries a different type so getting familiar with these is useful when learning both HTML and CSS Block elements have a fixed width and height which sometime span the entire page while inline elements are within lines of text meaning they have content floating beside them Another type of element which is often used is an inline block which is simply a block of fixed width and height within an inline context such as within a block of text Regardless of whether an element is inline or a block all elements have a number of core box attributes Those are shown in the image below div width px height px padding px border px solid black margin px For padding and margin we can also refer to each side separately on the same line In CSS when we are referring to each side the order is top right bottom left Take a look at the example below div top side padding px right side padding px bottom side padding px left side padding px padding px px px px We can also directly call out these by using the properties padding top padding right padding bottom and padding left The exact same properties exist for margin i e div margin left px Try it OutBelow is a demo div element which with some sliders Use the sliders to adjust the box model properties and see how it affects the div Quick Case StudyLet s think a little bit more about how box models work We create a new div and give it a width of px a padding of px and a border of px as shown below We also add px of margin div width px padding px border px solid black margin px How big is the box Since the width is px the padding is px and the border is px the total width rendered on the page is actually px To explain a bit more the width as shown in the diagram is the width excluding the padding Since we said the padding is px CSS adds px to all sides of the box That means px on the left and px on the right which is px in total When we add that to our width we get px Finally we have px of border the whole way around the div which is px on the left hand side and px on the right hand side The result is px px px or px DisplayThe CSS box model also has another property called display which among other things can allow you to hide an item Display also lets us set a specific HTML to block or inline For the purposes of the box model let s think about a few key properties none the item is hidden inline the item is inline i e inline with text it cannot have a width or height added to it block the item is a block i e it takes up the entire width and starts on a new line inline block the item is inline with text but it can have a width and height added to it in CSS contents the item is displayed as if its container does not exist and is added to the container above An example of the CSS box model display propertyLet s take a look at a quick example The code is shown below for an example where a span is forced to be a block element span elements are typically inline so this example will give this span the box properties of an element like a div span display inline width px height px padding px Box SizingThe way CSS manages padding width and border separately has always been a point of contention in the CSS community As such a property has been created to remedy this known as box sizing Box sizing lets us override this default behaviour Let s think about our px width box which ended up being px wide We can set box sizing to border box the width includes border and padding Our total width will now be px even with the padding and border content box the default behaviour the width excludes border and padding Our total width will now be px Now we have way more control and can set our widths with certainty that they will display as we expect them to on the page BordersBorders are another way we can affect the box model Borders can be defined as surrounding the entire element or on a specific side using border top border right border bottom or border left Here is an example div border px solid red border top px solid black A border property can be split out into separate lines too px solid red can be written as div border width px border color red border style solid Similarly we can apply these to a single side i e border top width border top color or border top style for the top side We can do this for any side The color accepts any color and you can learn more about colors in the color section the border style property accepts the following values none hidden dotted dashed solid double groove ridge inset outset Border RadiusFinally border radius lets us added rounded edges to our divs Note this does not affect the box model so the size of the element remains the same but it does affect its aesthetics It accepts any unit but I am using pixels as an example below The larger the unit the bigger the rounding Here is an example in code of how it looks div border radius px ConclusionThat s everything you need to know to understand the box model If you re interested in testing your knowledge I ve also made a quiz which you can check out here Thanks for reading	2022-07-16 10:44:57
