Bootstrap Get Started

Since Bootstrap employs a mobile first approach by design, the first text block with the class of d-md-block will also be visible on large devices. For example.btn-primary and .btn-secondary will give a blue and gray button respectively. With these in mind, we will solve these problems with the least amount of custom styles, taking advantage of the default Bootstrap styles where possible. Now that we understand the design requirements, let’s get started with the initial markup required. The code block above says, “for devices that have a minimum width of 768px …”.

Bootstrap is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. It contains HTML, CSS and (optionally) JavaScript-based design templates for typography, forms, buttons, navigation, and other interface components. One of the most convenient approaches to styling a project is by using pre-styled components. Bootstrap includes pre-styled components such as dropdown menus, alerts, or navigation bars that you can use when developing a project.

What is the difference between Bootstrap 4 and Bootstrap 5?

The grid system in Bootstrap is one of the primary elements. They create layouts of pages by using multiple columns and rows in which the content can be inserted. If the device screen on which the page is being viewed, gets bigger, the grid will scale up to 12 columns. The page is clean, responsive, and cross-browser friendly, but rather austere.

If you’re still not convinced whether Bootstrap is worth a try, here are the advantages of using it compared to other web development frameworks. Due to its popularity, more and more Bootstrap communities emerge. These are great places for web developers and web designers to share knowledge and discuss the latest versions of Bootstrap patches. List-border-y is a tiny class I have written to add borders only to the top and bottom of a list element. That’s the trick to move the column to the right — on larger devices. Align-items-center and justify-content-end do exactly as they read.

A Quick Note on Bootstrap 4

Bootstrap is one of the most popular web development frameworks out there, and it is used for developing highly-responsive projects in HTML, CSS, and JavaScript. Essentially, what Bootstrap does is reduce the time needed to get a modern website up and running. Additionally, the concept of a framework was also alien to designers, as many were used to development from the ground up. However, this proved not to be so, as it was quite simple to understand and work, without extensive knowledge of responsive design concepts.

  • By design, using Bootstrap means you’ll have a lot of divs in your markup.
  • We can choose to trigger this layout change at a screen size of less than 576px by using col-xs, or at a larger screen size of 768px with col-md.
  • This can be tricky to get right when you’re designing a website from scratch, and Bootstrap does a lot of the work here so that you don’t have to (more on this below).
  • With Bootstrap, you can conjure complex web pages from standard HTML and customize them to your needs.
  • By default, the pre tag will be displayed first, then the div .

Because it’s so popular in web development, there’s a good chance it’ll be included in your future employer’s tech stack. Bootstrap is a powerful tool that lets you quickly build attractive websites that look great on desktops, phones, and tablets. You can even eliminate the biggest drawbacks with a bit of extra time and effort. You might call Bootstrap a victim of its own success here. People everywhere are using Bootstrap to build their websites, which means that a lot of sites are built off the same template. Open-source products are great, but what happens when you have a problem?

Disabling responsiveness

Firstly, there are three div elements that are contained inside a single row. So we start a new row by adding a new div with class row. It divides the screen into 12 equal parts, and we need to specify which HTML element occupies which parts of the grid. So in short, any element will occupy a minimum of one grid in the grid system. Then we have the meta element, which is very important to understand when using Bootstrap. For this tutorial, our main CSS file will be bootstrap.css, and we must include that in all our HTML pages.

Bootstrap consists of a collection of syntax compiled in three primary files ‒ Bootstrap.css, Bootstrap.js, and Glyphicons. Keep in mind that Bootstrap requires a JS library called jQuery to run JS plugins and components. Bootstrap also provides additional classes like .img-circle and .img-rounded, what is boostrap which help to modify the images’ shape. The first container class provides a fixed-width container, while the latter offers a full-width container capable of adjusting your project to all screen sizes. Bootstrap comes with a predefined grid system, saving you from creating one from scratch.
