Their setup guide is indeed a host of useful information — links to CDNs, explanations on how to install with Bower, npm, and Composer, information on integration with Autoprefixer and LESS, a bunch of templates, licenses, and translations — but it is certainly not a step by step guide to getting started which very well might be in the spirit of autodidactism.
When I discovered Bootstrap a few years ago, responsive design was still gaining in popularity, and not necessarily the expected norm. Having only ever made websites from scratch, I was a little confused about the entire concept of a framework. It is a mobile-first framework and can claim to be one of the best CSS frameworks for building responsive website designs. In my last article I focused on building responsive websites using Twitter Bootstrap 2.
From that, you should have an idea of how Bootstrap works. Then, add another div which will contain the description. Add the class. After all of that, our header will look like this:. In this section, we will use some Bootstrap Grid to divide the section into two parts. To start our grid, we have to assign the.
The first section will be on the left and will contain a picture, the second section will be on the right and contain a description. Remember that a grid is divided into 12 columns.
In the first div on the left side:. After adding the the HTML elements on the right-side, the structure of the code will look like this:. Each item in our gallery will take up 4 columns remember, col-md-4 for medium devices, col-lg-4 for large devices. Cards in Bootstrap 4 make blog design so much easier. The cards are appropriate for articles and posts.
To create a card, we use the class. We need to add some CSS style to the cards:. After adding the Blog section to our website, the design should now look something like this:. In this section we will use the grid system to distribute even space between images.
Each image takes up 3 columns. The Contact Form section will contain a form through which visitors can send an email or give feedback. We will use some Bootstrap classes to make the design beautiful and responsive. Like Bootstrap 3, Bootstrap 4 also uses the.
A small group of developers in the company put it together as an internal tool to help create consistent web interfaces.
The project kept growing until at last they decided to release it to the public for free usage in Since then, support for Bootstrap has continued both by a number of the original developers as well as a large group of contributors. It has seen several major updates over the years the last one, Bootstrap 4, in January that have, among other things, added its famous grid system, flat design, a mobile-first approach and modern CSS.
By now, the framework is among the most popular web development tools on the net. Among other things, it has become the second-most starred project on Github.
However, what exactly does it do? A Front-end Framework As mentioned in the introduction, Bootstrap is a framework for front-end development.
In computer programming, a framework is sort of like a library. It contains tools, parts and existing functionality that you can use to accomplish standard tasks quicker and easier. In the case of Bootstrap, these standard tasks are creating design patterns like forms, menus, columns, buttons and other components you frequently need for websites. Bootstrap helps you set them up by offering a large number of CSS classes you can easily apply to HTML elements to create the site components you need.
That way, you can conjure complex web pages from standard HTML and customize them to your needs. In addition to that, Bootstrap comes with a number of jQuery plugins that can provide additional functionality such as carousels, buttons, tooltips and more. The important thing to remember is that Bootstrap gives you a lot of shortcuts for creating web pages that will save you time and energy.
All you need is a basic understanding of HTML and CSS to creates that are responsive, mobile first and compatible with all modern browsers. All clear so far? Bootstrap Tutorial Step 2: Setup and Overview In order to use Bootstrap, you first need to integrate it into your development environment aka web page. For that, you have two different possibilities: load it remotely or download and use Bootstrap locally.
However, for both, you first need something to load it into. For that, the first thing you want to do is create a folder on your computer or server for the project files. In this case, I will simply call it bootstrap. Here, create a new text file and call it index. Open it with a text editor of your choice e. As such, they can be loaded in the header and footer of your web page like other assets such as custom fonts.
The framework offers a CDN content delivery network access path for that. You can find it on the Bootstrap download page , further below.
Using the remote method is a good idea as many users will already have the framework in the cache of their browser. As a consequence, this is the recommended method for live sites. However, for experimenting and development, or if you want to be independent of an Internet connection, you can also get your own copy of Bootstrap.
This is what I am doing for this tutorial because it also results in less code to post. Host Bootstrap Locally An alternative way to set up Bootstrap is to download it to your hard drive and use the files locally.
You find download options in the same place as the links to the remote version. Once you have done so, unzip the file and copy its contents into the same directory as index. In your case, make sure your path corresponds to your actual setup. For example, the names of the directories might differ if you downloaded a different version of Bootstrap. Include jQuery In order to get the full functionality of Bootstrap, you need to also load the jQuery library.
Here, too, you have to possibility to load it remotely or host it locally. In the first case, you find the link to latest version of jQuery here. These are included in the downloaded version of the framework and you also find links to remote sources in the same place as before.
However, we will load it in a different place than the style sheet. Instead of the header, it goes into the page footer, right after the call for jQuery. Plus, now the fun begins. At the moment, when you navigate to your sample site, you should simply see a blank page. Time to change that. Add a Navigation Bar The first thing we want to do is add a navigation bar to the top of the page. This allows your visitors to get around your site and discover the rest of your pages.
