海外TECH	DEV Community	Learn CSS layouts by example - Flex (part 1)	https://dev.to/mohsenkamrani/learn-css-layouts-by-example-flex-part-1-4g62	Learn CSS layouts by example Flex part Mastering CSS layouts is one of the most challenging parts of web design Specially if you just go to the documentations and start reading dry materials with very basic examples it s even harder to get a practical understanding of the concepts In this series of posts you ll learn CSS layouts through practical examples you can use in your projects PreparationThe simplest way to directly see the result of our work is to build our website with DoTenX UI builder If you don t have an account there you can create one for free and follow along this tutorial It s worth mentioning you can build unlimited number websites on DoTenX for free and whenever you reach the initial limit of your projects you can ask for an increase Note When you create a project on DoTenX switch to advanced mode because we want to have full control over the html elements and styles Example Profile cardLet s design the following layout as our first example CSS properties we learn displayflex direction column justify contentThe component is borrowed from a great design by Syed Raju here Step We start by adding a Box which renders a div element to our page Now we go directly to the CSS properties section in the Styles tab where we directly add the CSS properties Add the following property value pairs display flexflexDirection columnalignItems centerwidth pxbackgroundColor hsla The very first step in adding applying flexbox layout is to set display property to flex which creates a flex container for us an area of a document laid out using flexbox We want the elements in our flex container to be placed in a column that s why we set the flex direction to column You might notice we used camelCase instead of kebab case to refer to the CSS property and that s because DoTenX UI builder follows ReactJS naming conventions When you render the page the resulting CSS properties will be rendered in kebab case We want to horizontally align children elements flex items in centre that s why we set align items to center Finally we set the width and background color values Step Add an image to the div by dragging an Image element from the Elements tab and dropping it inside the Box I ve used this image from Freepik but you can use the url of the image you like or upload an image Step Add a Tex element after the Image element which will ultimately render a p tag Set the text and size to the desired values I ve set it to xl in this example As our focus is on the flexbox I m using the simple options of UI builder to set the font size which is another advantage of using DoTenX UI builder allowing us to focus on what we want Step Exactly same as step just with a different text and a smaller size and a slightly faded color Step As a final touch to implement our component more accurately we set the top margin of our texts and give a border radius of px to the flex container we created in step and give it bottom padding In this published page you can see the end result Example Profile card rowThe same beautify design can be used to show more interesting features of flexbox layout CSS properties we learn flex direction row justify content Step Add a Box with width of with the following properties display flexflexDirection rowwidth Using these properties we have made the div a flex container with a horizontal layout Remember that the default value of flex direction is row anyway We also set the width to make sure our div expands the entire width of the page Leave a comment if you know an alternative for width Step Add four copies of the profile card we created in the Example to the div we created in Step To avoid repeating the steps you can use the trick I used Just export the element from the Layout tab and add the exported element to the Box This is very similar to the concept of re usable components used in advanced scenarios such as using React Vue etc Export Use After adding the cards to the parent div you can check the preview and you should have something like this Step As you can see in the preview all of our items are placed next to each each other without any space between them To fix this set justify content property of the flex container Box to space around and this is the result Here you can find the published result all the image are from Freepik Try it Now resize your browser window to see the result in smaller screens Do you see any problem How do you think we can solve the issue Comment down below and don t forget to follow for the next parts of this series showing you how to deal with such cases SummaryIn this tutorial we saw how to build vertical and horizontal layouts using Flexbox We learned about some of the commonly used terms such as flex container and flex item We also learned about setting the direction of the layout and adjusting the arrangement of the flex items It is worth mentioning as a rule of thumb if you want to set the order of flex items in the same direction as the flex container use justify content otherwise use align items If you have any questions feel free to ask and see you in the next tutorial	2022-11-27 09:06:24
