Align-content Determines the default for how cross axis lines are aligned. Align-items Determines the default for how flex items get placed on the cross axis on each line. Optional arguments: left, right, center, space-between, space-around. Justify-content Determines how content gets placed on the main axis on the current line. Possible arguments: row (default), row-reverse, column, column-reverse. The cross axis is perpendicular to the main axis. The main axis is the axis on which the items align with each other. Axes Each flex box contains two axes: the main and cross axes. Any text within the container element is wrapped in an unknown flex item. Flex item Any direct child element held within the flex container is considered a flex item. Using the CSS display property, the container can be defined as either flex or inline-flex. The following terms are associated with the flexbox layout model.įlex container Parent element that holds all flex items. Īs of December 2022, 99.68% of installed browsers (99.59% of desktop browsers and 100% of mobile browsers) support CSS Flexible Box Layout. Flexbox is originally based on a similar feature available in XUL, the user interface toolkit from Mozilla, used in Firefox. ĬSS modules included solutions akin to this, like Flexbox and grid. In the 2010s, the intensive use of popular JavaScript layout frameworks, such as Bootstrap, inspired CSS flex-box and grid layout specifications. In the 2000s the intensive use of the Web by mobile agents motivated "liquid layouts" and responsive elements for the growing variety of screen sizes. Individual items within a flex container may also be automatically rearranged to suit the available layout space. The flex directional flow can be specified rightwards, leftwards, upwards, or downwards. Moreover, the flex layout is less restrictive in terms of content flow than that of other CSS layout models, which are generally uni-directional. Flex boxes can adjust in size-either decreasing, to avoid unnecessarily monopolizing space, or increasing to make room for contents to fit within its boundaries. One of the most defining features of the flex layout is its ability to form-fit, based on its viewing environment. In short, HTML specifies the content and logical structure of the page, while the CSS specifies how it looks: its colors, fonts, formatting, layout, and styling.ĬSS flex-box layout is a particular way to specify the layout of HTML pages. To save time and code, when defining media queries we'll use mixins and loop the breakpoints we defined above.Most web pages are written in a combination of HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets). Remember, on our SCSS map, are keys and the pixels are values. Next, define various screen breakpoints in the SCSS map. Open CodePen or any code editor and go through this with me, these step by step.□ How to Enable SCSS in Codepen □įirst, define the border color, gap, and padding values in your variables. SCSS is a preprocessor of CSS which gives us much more functionality than regular CSS.įor example, we can nest child classes inside their parent class, store values in variables, and much more. Along with that, we will define some media query mixins to save time and avoid code repetition. Project Setupīefore coding, we need to save some values in variables and clear the default browser styles. Throughout this tutorial, you'll learn how Flexbox works, how its various properties and values work, and how media queries work (which help us make responsive websites). You need to know a little bit of HTML and CSS. You can reference it while doing the project and experimenting with different values. This chart contains every possible property and value you can use when using flexbox. And, depending on the flex-direction property, the layout position changes between rows and columns. So how does Flexbox architecture work? The flex-items are distributed along the Main Axis and Cross Axis. This is what Flexbox helps us do – create responsive layouts. At the same time, we need to make responsive layouts for various screen sizes. In the same way, we need a blueprint to layout our content across our browser. We need a blueprint when constructing a house.
