Episodes

25: Season 1 Wrap Up 16.09.2020

In this closing episode, we do a whirlwind recap of our entire first season! We go over every episode, from the box model to z-index to animations and functions and color. Listen as we recount our favorite tips and tricks and discuss what we learned in the process of making this podcast.

24: Blend Modes 09.09.2020

Today we are talking about CSS blend modes! Blend modes are super fun and allow you to specify how you want elements to interact in terms of their overlapping pixel values on the page. Links: mix-blend-mode → https://goo.gle/3m5L9mP   Isolation: Cascading Style Sheets → https://goo.gle/2GIDjiX  

23: Filters 02.09.2020

In this episode, we're talking about CSS filters! We can alter the pixels of our web apps in similar ways to our favorite design tools. From recreating Instagram filter effects, to blurring background for better legibility, we dive deep into what CSS and filters can do.

22: Animation 26.08.2020

In this episode, we're talking about CSS animations. With CSS animations a developer creates a set of keyframes, and then uses a variety of animation properties to describe how the element moves through each of the possible keyframes.  Links: Animations Level 1 Spec → https://goo.gle/2DhV0V2   Easing Level 1 Spec → https://goo.gle/3kWoWap   Scroll-Linked Animations Draft Spec → https://goo.gle/39V...

21: Gradients 19.08.2020

In this episode gradients take the stage as we share syntax secrets, tips and tricks, and probably teach you about repeating-conic-gradient. By the end, you'll be savvy with color stops, transition hints, and all the ways to interpolate color in your design.

20: Functions 12.08.2020

In this episode we talk about the runtime dynamic side of CSS, commonly recognized as a CSS function. Today, in similar fashion to other episodes, we'll be doing a massive overview of all the CSS functions, to be later deep dived.  Links: CSS Tricks Guide to CSS Functions → https://goo.gle/2XRb7Ah   CSS Variables → https://goo.gle/2XRb2fX   Functional Notations Spec → https://goo.gle/3gJwavQ   Cub...

19: Z-Index and Stacking Context 05.08.2020

In today's episode, we're talking about z-index and stacking context. This is a pretty in-depth topic, but it's something that we see all the time and it can definitely bite if you aren't aware of what's going on.

18: Focus 30.07.2020

Today we discuss: focus! Focus  is something we regularly deal with when writing styles and is also very tied to markup and attributes like tabindex, so we'll be discussing all of those things in this episode!

17: Shadows 22.07.2020

Today we're talking about shadows! Box shadows, drop shadows, text shadows, and everything in between. Shadows can exist all over our UIs without us even realizing it because sometimes, they just look like borders.   box-shadow spec →  https://goo.gle/32JVdL4   text-shadow spec → https://goo.gle/2ZMdiGo   Sass pixel art → https://goo.gle/3hsjQjp   Any image to CSS → https://goo.gle/2WKnm0L   Easin...

16: Borders 15.07.2020

Today we're talking about borders! And while this sounds relatively simplistic, borders in CSS can actually get pretty complex very quickly. It's not just color and style that you can adjust, but also also border images, where you control how the image repeats itself and what slice of the image you want to show.

15: Pseudo Selectors 01.07.2020

In this episode we break down functional and regular pseudo selectors, CSS's special hook into encapsulated element states. We can't control them, but we can leverage them to provide rich interactive feedback from our interfaces.   Links: Selectors Level 4 → https://goo.gle/2ZiJLmt   a:link vs. a styling demo → https://goo.gle/2NGwWgd   Hacking Visited for Una's Blog → https://goo.gle/3eIo0TC   :f...

12: Logical Properties 27.05.2020

The days of  euro-centric spacing like `margin-top` are limited: instead, say hello to `margin-block-start` to define space that works within any linguistic context based on your layout needs.

5: Inheritance 08.04.2020

Inheritance and its effects in CSS are found all over your styles, almost invisibly, until further investigation through devtools or docs. In today's episode, we illuminate the aspects of inheritance, how they're useful, things to watch out for, and of course tips, tricks and vocabulary.    Links Spec: css-cascade-3 → https://goo.gle/39KZPR6   List of inherits or not → https://goo.gle/2wn0yKF

2: Selectors 18.03.2020

Get ready to learn some new CSS vocabulary! In this episode we talk about selectors, a syntax used to find elements (subjects) in a tree.

We go over universal selectors, type selectors, class selectors, ID selectors, attribute selectors, pseudo selectors, complex and compound selectors, and various combinators. A lot of things...

1: The Box Model 12.03.2020

Where do scrollbars go, inside or outside the box? In this episode Una and Adam answer that and much more in their discussion of the CSS box model. Everything in CSS starts as a box, and while that's a straight forward concept to initially think about, it can get complex quite quickly. Not only do boxes surround elements, but letters in a sentence each have a box too. How many boxes are there!? Lo...
