What is CSS?

CSS (Cascading Style Sheets) is a style sheet language used to specify the presentation of a markup-language-authored page. It allows authors to apply predetermined rules for the presentation of a document’s content, such as font size, color, and spacing between elements on a page. CSS is used to separate document content from the document presentation, enabling the separation of document layout and content processing responsibilities. This allows a single HTML document to include both content and layout information, thereby reducing complexity and allowing the source document to be repurposed for alternate media.

It is a set of guidelines that tell the browser how to present the page. Each browser has its own implementation of the rules in the CSS spec, and the different browsers interpret these rules in different ways, resulting in slightly different renderings on different devices.

How do I get started with Flexbox?

There are several approaches to getting started with Flexbox. The first thing you’ll need to do is make sure you have a properly configured browser that supports Flexbox. From there, you can start by exploring the different layout options that are available with the Flexbox!!

In this guide, we’re going to show you how to use Flexbox to build a fluid based layout for a home page. Let’s dive right in!


This approach does not require any sophisticated coding or plugins, making it an excellent choice for novices. All you have to do is create a container for the things and arrange them in the desired order.

  • First, launch the HTML editor on your computer.
  • Then, create a new div and assign it to an ID. Make sure to give it the class “flex-container” as well.
  • Finally, create a few more divs with IDs that match the names of the columns you would like to add. Give them the class “flex-item” and then assign them values for the properties you want to change.
  • After adding your elements to the document, simply write some CSS in the same file to change the styles of the <div>s. You can also add additional styles for the <div class=”flex-container”> tag if you like.

Now, we’ll explore how to use HTML’s flexbox property.

  • Flexbox is a CSS layout module attribute that allows you to determine how items in your row should be ordered. It enables you to define width and height characteristics for each item in your row depending on specified constraints.
  • We must first establish a container before we can begin constructing our row. We’ve established a div in the code below to act as a container for all of our things.
  • Everything will be placed in this container, and the display property will be set to inline-block. This ensures that the material is arranged in a row rather than piled on top of each other.
  • Following that, we will establish the height and width of our items based on the rule we defined in our flexbox setup.
  • Finally, it is necessary to write the styles that will govern the layout. The code block below demonstrates how we established a style for each item in the grid and utilized the “flex” attribute to set the alignment of the item with respect to the other items in the row.
