CSS is the de-facto way of styling web applications. Although various other approaches exist (CSS-in-JS, styling inline with JS, etc.), the simplicity of this way ensures it is a timeless method for defining the way our end result looks and behaves.
In this training we will explore an atomic approach towards styling. The main idea is to use small, composable utility classes that augment the HTML in order to obtain the desired result. This provides great flexibility, decreases CSS specificity and allows for greater maintainability in the face of future changes. Along the way, we will dive deep into both basic and advanced CSS knowledge and APIs (positioning, display types, flexbox, grid, etc.).
This training assumes the participants are already familiar with basic CSS knowledge, such as common rules, selectors, classes vs. IDs, etc. Thus, the aforementioned concepts will not be discussed or detailed during the training.
This training targets intermediate developers who would like to upgrade their CSS knowledge by finding out more about how CSS works in-depth and understanding what it takes to build a scalable and maintainable CSS codebase.
