I wish when I started learning CSS that they would just start with teaching rem instead of px. It would have saved me a lot of time and brain power.
@jackdavenport5011
The main reason I started using em/rem is because it just looks more consistent since all of the font sizes are multiples of the base font size which makes the design of your site look more consistent. I had no idea about the accessibility benefits but I'm glad I do now! Great video :)
@dasten123
For some reason, I have never even thought about using rem on media queries. But it makes total sense!

I've been setting html {font-size: 10px} then body {font-size: 1.6rem} etc for a long time. After watching this, I set the browser font size to 'very large' and the font-size on my web page stayed the same! (as I'd predicted after watching your video). But, following up on an earlier comment on this thread, I went looking for a vscode extension and found one that works: "Convert px to rem" v0.0.10 - by gwanduke. So you could write your entire CSS file in px, then select all/some, then Ctrl+Shift+P, then type: convert px to rem of selections. PS. Excellent video, very informative!

Oh my god, I was searching for how to use Rems and ems a few minutes ago and your video was on the suggested panel! I'm so happy I'm subscribed to this channel!

This is the best argument I have seen for useing rem over px. Great video

Thank you for considering accessibility in this video! I AM someone who uses the built-in font size setting in my browser for accessibility reasons and always wondered why it didn't always affect things in the way I expect. I see many comments from viewers who don't understand why someone would use the font size setting rather than just zooming. For my own needs, the answer is that the the font size setting's intended behaviour specifically involves increasing the font size across all websites. Zooming w/ ctrl+ or a page's menu increases the size of everything, which is not always what I want. It also functions on a per-website basis unless you use a global zoom setting, which is right next to the increase font size setting in the browser I use anyways. It's not any more work to set a global font size vs a global zoom setting on my end as a user, and font size is more likely than per-page OR global zoom to give me the behaviour I want. If you just need to zoom in to get a better view of one particular thing every so often, per-page zooming works just fine. For someone who needs or prefers ALL fonts to be a certain minimum size across all websites, without significantly impacting the viewing experience of other elements of the page, setting the font size setting in browser is a much better choice. If you read the Josh Comeau article Coder Coder linked, his article explains much the same thing as I've found through my own personal experience.

Love the way you explained every case with examples. Great work. Thank you!
@msegmx
The "rem" function is a great idea. One improvement though, instead of concatenating with "rem", better multiply by 1 rem, so that the result is treated as a unit "rem" rather than a string "rem". Instead of "math.div($pixel, 16) + rem;" use "math.div($pixel, 16) * 1rem;". That way, you can reuse the function in other Scss calculations.
@E6hosting
It took me 10 minutes until I noticed you weren't Kevin Powell, excellent video. Thank you for explaining the maths I always thought rems and ems were just voodoo magic numbers.
@christiaanterveen4633
I started building a new Drupal theme for the first time in 10 years and came accross rems in the coding standard. Your video really helped me understand how to use them and why this is important. Thank you.
@zshn
I really liked how you explained the merits. Very well done. On the topic of using var vs SCSS functions; I think the issue root vars solve is of distributed values being harder to modify / maintain / update. root variables help centralize the different values used across the system and SCSS functions are not a replacement to it. Even if you use a SCSS function to convert pixels to rem; you now have hundreds of places where magic numbers are used - 16, 32, 24, 1000, etc. As leads / reviewers; I'd like a more consistent model of defining & standardizing those values. So both root vars and SCSS functions can and should be used together. One (root vars) helps in make change configurable and centralized, the other (functions) makes it consistent and reliable.

My mother knows how to zoom in but prefers a larger font size. Some people said users can just zoom in but I find it a bit annoying when having to swipe left and right continuously just to read text on a website. That's why browsers support changing font size.
@archer201977
i moved on to rems, em for long time, i can say you are correct in many ways.
@ProudIndian-s2v
Atlast I found someone who talks on the issues I am facing in the design
@jordallef2586
Hello! I'm new to English so I'll try my best to show my gratitude, I must have to get advanced in english and consume much about programming, because here in Brazil the resources are rare. I think I understand what you propose to show in this video, I like the level of English it's easy to know what you are talking about. So starting today I will just use Rem/Em, thanks too much for this video! Peace ✌️
@j-lewis
Girl, you're the eyes-opener, you know that? I'll subscribe, good stuff!
@chrisbergr
Oh thank you! I finally got the point why we should use rem/em in media queries. And it’s so obvious!
