What Is Bootstrap: A Beginner’s Guide to Bootstrap

For example, the “source code” version of Bootstrap lets you access the Sass port. This means it creates a custom stylesheet that imports Bootstrap, allowing you to modify and extend the tool as needed. Bootstrap’s primary objective is to create responsive, mobile-first websites. It ensures all interface elements of a website work optimally on all screen sizes. Bootstrap is an open-source and free CSS framework that helps in directing a responsive device-friendly mobile-first front-end webpage development tool.

The markup above will create columns that take up all the available width within the row. The columns will stack vertically with a 100% width. It’s pretty simple, and in no time you’ll get used to this. You assign 8 of the columns to the bigger column, and the remaining 4 to the smaller column. According to Bootstrap, there are 12 columns within every row.

Bootstrap is more than efficient to create a responsive and mobile first website but it is not the best in the industry. There is an alternative of Bootstrap named W3.CSS which is smaller, faster, and easier to use. A website is called responsive website which can automatically adjust itself to look good on all devices, from smart phones to desktops etc. Cloning a site can help you familiarize yourself with web development and design.

The takeaway: when to use Bootstrap

The font is now different, the spacing between each text block is altered, and the link has a different style. If you visit a website that has a link to a CDN resource, the Browser will load a cached version of the library. This is a version ‘stored’ in your Browser’s memory. If it finds none, it will make a request to fetch the requested resource. As in the example above, the addition of the cowbell class to body will give the entire document a cowbell color.

This will give the text a slightly transparent white color. With that you should have a section that looks pretty good. Just use the 1kb script that magically solves all your problems and algorithms. Now let’s apply the knowledge of grids to the project being built. When you take a look at the final design, you will realize that there are categorized sections of content. If you have “Hello World” displayed on the screen then you’re ready to follow along without any glitches.

Bootstrap is a framework

Twitter Blueprint was the first name for Bootstrap and was developed on Twitter by Mr. Mark Otto and Jacob Thornton. It was released as an open-source product on GitHub in August 2011. The framework is primarily built to encourage design uniformity and reliability of web pages across applications. List-unstyled is a bootstrap class that removes the padding and list style that comes by default with unordered lists ul. Since columns can be nested, we can include another column to house the side by side text block on large devices. In this case, the image block and the content area will occupy 50% of the available width.

Every element sits on a well defined grid structure. It is also possible to add the spacing to say top and bottom sides of an element. In the same manner you may add the same spacing to the left and right of an element too.

This will create some spacing between the image and the caption, and the text caption will be given a slightly calm color. Bootstrap allows for the use of two class names, figure-img and figure-caption As you may guessed, they are both used on the image and text block respectively. The correct way to do this is to contain the images within a figure tag and have the text block within a figcaption block. If for some reason you have styled an image to have rounded borders, you can remove the rounded borders with Bootstrap by adding the rounded-0 class. You’ll find the image having slightly round borders.

I will be using a question and answer method to explain the use of these Bootstrap styles. You just go ahead and add the class name, .cowbell to any element. Under the hood, this is the same way Bootstrap works. In the same manner, there exists a set of Bootstrap CSS classes that have been styled within the library.
