# Math.abs() & Infinity, Revamped Box Model & Position Absolute

### December 31st 2023 - January 6th 2024

Hi, let's talk about what changed in BigBinary Academy this week!

### Math.abs() and Infinity added in JavaScript

Going through the course and solving practice questions with students made us realize the importance of `Math.abs()`

and `Infinity`

.

We have added them to the course.

### Improved the Box Model Chapter

The Box Model is an important concept in CSS. We have improved the lesson by adding more visual examples. We have spent some time on the visuals so we hope that they will help students understand the concept better.

Checkout the new Box Model Chapter.

### Improved the Position Absolute lessons

Our Position absolute lesson was a bit confusing. We have improved the lesson this week with the help of student feedback. It should make more sense now.

Checkout the improved Position Absolute lesson.

### Added Float Chapter to CSS good to know course

The Float concept is something that a new developer can avoid learning if they understand Flexbox. But, it is still an important concept to understand. We have made the decision to move it from the Basic Course to the CSS Good to Know Course. This way, a student who is inclined to know more can learn it, but someone who wants to simply build working layouts can skip it.
