Creating Interfaces with Bulma

By: Jeremy Thomas, Oleksii Potiekhin, Mikko Lauhakari, Aslam Shah, Dave Berning

Overview of this book

Bulma is a lightweight configurable CSS framework that handles all the hard work of Flexbox for you. Bulma makes creating web interfaces an easy and interesting job. This book begins with an overview of the basics of Bulma ? its terms and its concepts. Then, while designing a login page for your application, you’ll learn how to use the various tools provided by Bulma to create HTML forms and control their layout and flow. In the later chapters, you’ll design an admin area for your application, thus learning to use Bulma’s navigation and menu components. You will also add the components to your user interface for common things such as boxes, lists, and media groups, and then create pagination. As you progress through the book, you’ll create and layout some other components for your interface, including tables, design dropdown lists, and finally to integrate your web application with JavaScript. By the end of this book, you’ll be able to use the features of Bulma to your advantage and build web interfaces quickly and easily.

  • component variables are specific to each Bulma element or component, and reference either a previously defined variable, or a new literal

This can create a chain. For example:

  • In initial-variables.sass, the color blue uses a literal value: $blue: hsl(217, 71%, 53%)
  • In derived-variables.sass, the $link color uses that shade of blue: $link: $blue
  • In breadcrumb.sass, the breadcrumb items’ color use that link color: $breadcrumb-item-color: $link

This provides Bulma users with a lot of flexibility in terms of customization:

  • You can update the $blue value and it will be reflected throughout the website
  • Or you can set...
