It utilises the CSS grid system and flexbox properties to create responsive websites in a fast and easy manner. It is a free tool which is available online for every front-end web developer to use. One can incorporate Bootstrap as a whole or even as a module. On the official bootstrap website, you can also find a starter HTML template for using bootstrap in your website.
If you wish to not download bootstrap on your machine, you can also add it as CDN via jsDelivr, the links for the same are:
These links can be copied directly from the official Bootstrap website. The latest version of Bootstrap is v5.0, you can explore the official documentation or in case you are following any online tutorials make sure you are using the same version which is being taught to you or else you will see some differences in your output and the tutor’s output. However, no matter which version is being used, the components are more or less the same and with every version, they are only upgraded.
We will be using version 4.5 for the purpose of this blog.
What are we building today?
We will be building a shoe-shopping website today. While you must be wondering that it requires a lot of pre-requisites to actually start building one, let me make it clear that we would be only working on the front-end aspect of the website today.
Let’s choose a colour theme for our website. While I can suggest you with amazing colour, how do you actually pick one yourself in case you encounter such a project on your own? It is fairly simple, either match the colour scheme of your website with the hero image or match the hero image with the colour scheme of your website.
Since we are looking for a colour scheme here, we will go with the former approach. Pick an HD image of a shoe online and start working on it. Some examples of websites where you can find images to work on are Unsplash and Pexels.
Sample Shoe Images:
Did you notice how the background is complementing the color schemes of the shoes? This will be our ideology behind picking the color scheme for our website. You might have to work with photoshop a bit to actually extract the image from the background, but trust me, it is worth the hard-work you are going to put in.
Now, let’s build a mind map of the website we are going to build: We need a navigation bar, we need a hero section and since we are using Bootstrap today, let’s throw in a carousel there. After that, we need an about section which will explain in a few words about the vision of the shoe company and a beautiful square picture complementing that vision right beside the text.
Now that we have compelled the users with our beautiful images and catchy text, it is time to display our products, let’s have three product categories on our website: shoes for men, shoes for women and shoes for kids. After this, let’s build a footer with all the links and FAQs for the company.
How to Build a Navigation Bar?
In our navigation bar we require the following components: Brand Name, About, Dropdown list for products and Contact Us. This is how the code for your navigation bar will look like:
The code for navigation bar can be easily taken from the official Bootstrap documentation if you are just starting out, however, once you get used to it, the classes and the structure will start coming naturally to you. In the official documentation, you can also find variations of navbars in the terms of colors, layout and other navbar items such as search buttons and search text field.
How to build a Bootstrap Carousel?
A carousel is a slideshow of images which look visually attractive in the hero section of a webpage. We would be utilising Bootstrap carousels to add some images, text and CTA buttons. We would be adding three main images on our website keeping in mind that they have to be in high definition and in accordance to the color scheme of our website.
We will be using a carousel with captions for our website, the code should look like this:
Since we required three images, we added three carousel-items, this number can be increased or decreased as per requirement. In place of the caption, you can also add in call-to-action buttons.
How to create the About Section?
Bootstrap has a jumbotron component which lets you add beautiful typography and content that stands out from the rest of the page. While it is generally used for the hero section, we can definitely experiment and put the about section in there.
The code for the same is:
You can also add in a strong image which floats to the right of the container. Since we do not need any buttons here, there is no need of adding one.
Understanding Bootstrap Grids and how to use them
Imagine your web page is divided into 12 parts along the width of the webpage. These are the 12 parts that are utilized with flexbox properties in Bootstrap Grid system. It enables us to plan out how the website will look on the desktop and how the website will look on the mobile nicely.
For example, in our webpage, after the about section, we want three categories of products to be displayed – products for men, products for women and products for kids. On a desktop, we want that these three containers are displayed in one-row side to side, however, on mobile, we want them to be stacked one on the top of the other.
Remember that we had 12 parts on our webpage, now we want 3 columns in one row, which means that we want one column to cover 4 parts, therefore we will use col-lg-4 for each column in the div container with the class row.
The code for the same is as follows:
When the screen size changes, the column layout changes according to the breakpoints. The breakpoints for Bootstrap are at 1140px, 960px, 720px and below 540px. This is the reason why a column which was taking up as much space as 4 parts on a desktop, takes up as much space as 1 part on mobile screens.
How to make a Footer?
A footer can be made without bootstrap as well, however, adding the class container gives a nice look because of Bootstrap’s design centric CSS.
Here is the code for the same:
Before the footer, you can also add in a horizontal rule using the <hr> tag, it will offer a visual bifurcation from the main content and the footer. You can add in as many links and more content in the footer as per your requirements, however, avoid filling the footer with unnecessary information and links. Doing so will make your footer look cluttered and the user will be overwhelmed with information.
Combining everything together
Now you have every component ready. All you have to do is combine them all together in a file and your website will be ready to go up and running. You can easily deploy your website using Netlify or GitHub pages. Share your output on your social media handles and tag Coding Ninjas.
Feel free to experiment with other components of bootstrap.
