You don't have any idea how much you have helped me with your videos.. I literally was on the notch of giving up css.. but now .. this is the one of those things about which I feel confident . Thanks a lot sir . Kudos to you.

[@KevinPowell]

That's amazing! Thanks so much for letting me know, that makes my day 😊

[@xClown55]

Same here, css back in my college years would be as frustrating as js now it feels kinda easy

[@Waqar_Ahmed75]

Same here...

[@zettai8087]

Wow. I hope I'll be able to share a testimony like this

[@zettai8087]

Cus I feel I just don't know how to use css to make a website look jot it ought to look and I'm frustrated

[@RealCaptainAwesome]

Whenever I question my choices that lead to me becoming a back end engineer, I watch one of your wizardry videos and feel much better.

[@KevinPowell]

🤣🤣🤣

[@zorokutend]

I choose to be on the both sides. Trust me, when you know how it works. You feel like you are god :D You can control everything in the eco system. And that feels really GOOD . Oh yeh

[@gg-gn3re]

Yea I've worked with dozens of front end guys and he knows way more than they knew. I know about the same as they did and can figure my stuff out. The lack of front end knowledge is very obvious on many sites, facebook for example uses the old 960px layout from the 1990s and is very static looking and old fashioned. It works I guess, but it is obvious they have no clue what to do there or how to fix it.

[@luizinniziul2976]

same feeling

[@elvissautet]

😅😅😅😅😅

[@bumbleguppy]

Just like the best cooking videos, showing the underlying "why" instead of simply specifying "how" imparts an understanding that can be applied to any recipe and not just the one you're working on. Thank you for your style of video.

[@pkunzel]

"They don't live in isolation, they live in relation" That is the biggest challenge I have when teaching CSS. Amazing video!

[@yourlinuxguy]

Try Grid?

[@tdematos]

The way you understand how everything comes together is unbelievably easy to understand! Definitely earned a new subscriber! 🙏

[@the-real-tridder]

great information mate, really apprecite the time you take to explain these really important concepts. The importance of relationships is so underrated when most people discuss css.

[@francopdx]

Thank you for all the tips! The differences between flex and grid in regard to parent vs child influence was very enlightening! I've been using flex for almost a couple years, but it was just a few months ago that I really started dabbling with grid.

[@BinaryStar10]

Notes to myself: -Parent dictates children's width. Children dictate height... unless you set height and possibly cause overflow issues. -A simple wrapper with max-width and margin-inline: auto. -Collapsing margins - child's margins can reach outside parent (margins merge to parent). This can be prevented by removing margins from child, adding padding to parent or changing to a formatting context where collapsing margins don't exist (such as flow-root, flex and grid). -Using flex you can have even sized columns with flex: 1. But if columns have varying sized paddings, they are not even sized. Grid on the other hand takes padding into account when calculating size and therefore columns are even sized if they are set to be even.

[@MasteringGravity]

Thanks for the notes! Mind if I also use these? 😁

[@carldrogo9492]

Use Grid NOT Flexbox. 😉

[@BinaryStar10]

@@MasteringGravity Feel free! :)

[@IamPetrus]

Hey Kevin, I was having issues with a very basic relationship between a parent-child situation kept with flexbox. Your video came up here and then I understood what was going on after a terrible feeling of frustration. And man, you named them all! Gracias Kevin!!!

[@lauramangu2516]

Amazing content as always! You are my primary source of learning when it comes to Css, Kevin! Kudos to you and thank you for these great videos. Please never stop :)

[@okthatsnice]

Dope!!!!! This is the exact question I've been wondering about for so long -- just how everything fits together and how relationships play out. Bought your CSS Demystified course just now. Excited to get a firm understanding of the fundamentals.

[@WadieGamer]

I've been following your videos for almost a year and I want to thank you so much for making my CSS learning much better.

[@andrewferguson7859]

Thank you for the clear, and quick review this topic. I always learn something, and that was certainly the case here. Just yesterday I was working with flex and grid and got myself thoroughly confused. Thanks to this refresher, I better understand what was confounding me so much yesterday.

[@tk4776]

The last tip, where flex let more control to child and/or siblings, and grid allows more control to the parent was so illuminating. I know now how to initiate a layout based on my content.

[@ilovelctr]

Omg, this is so splendid! This is the first time I've watched your video, and I immediately subscribed. Your explanation makes utter sense out of CSS, whereas I'd say CSS seems to make no sense for most devs. Thank you so much for sharing your knowledge.

[@jpisello]

That last thing with the padding on the flex items blew my mind! Learned something new today, so thanks Kevin!

[@goannacs6861]

I learn HTML and CSS. I even attend some kind of online school and Udemy. But you are the only one who really helps me understand every bit. You have such a calming and logical way to explain things. You just feel secure about it afterwards. It's strange. It's like you were born for this stuff haha 😆

[@aarondeimund6898]

Thanks for making these! I'm a developer in the I.T. department of a manufacturing company and the only one on my team with a good grasp of css, largely because of your videos. Thanks for helping me make my corner of the internet a little more awesome!

Great stuff for someone who is starting out and facing common issues in CSS.

Thanks Kevin for explaining some of the most confused things of CSS . I think you should add the link to the course in the description. It might help people reach to the course easier. As well as make your video become more friendly to search engine.

An excellent video showing the differences. Thanks for this simplified explanation of this difference. I really prefer CSS grid for the rough layout and the content can be arranged with flex then. And I think this is the way it meant to be, right?!

[@a5tr00]

I basically started learning about CSS from your videos. And time to time I hear people say “I hate css”, “it is so frustrating” etc… Man, I don’t understand them… Is it because you, Kevin, makes CSS look so easy , simple and lovely? I don’t have any other explanation:)

[@TroenderTass]

You don't understand people get tired of hasseling around with stupid layouts and inconsistent properties that might not even work un certain elements, or in certain browsers, when they can do more interesting programming in stead?

[@EricRohlfs]

30 years and I never thought about it about width an height had inverse relationships with children. Mind blown

That padding in flex really caught me by surprise. What if the padding is applied to a div nested within the flex child? Would it still cause issues? Great video btw.

[@Bkamron]

I'm kinda happy I started CSS way back I'm the late 00s I still use techniques from the XHTML days (remember those days?) And the somehow still kinda work for me. If I had to learn all over again, it would be so daunting I'd probably give up.

[@danielgarner100]

Great video

[@octothorpe12]

That's I think the important thing to consider: Flex is 1D, so it gives you the illusion of columns. They'll only ever look like true columns if you explicitly make them all the same (and even then everything gets wild when items wrap). If you want 'set and forget' true columns, you kinda need to go Grid.

[@glebpanchenko5500]

cool, you are a great teacher

Wow Kevin, really nicely explained. I have been doing these kind of things rather instinctively and successfully but never really breaking it down this way. I acutally had a few “oh right” moments. Thanks for joggin the ol’ noggin

Yeah I think a lot of the time, it clicks for some people on a more instinctive level, which is great when it happens!

[@George10767]

I have discovered that the tags "div" and "article" have identical functions. Please say if you disagree. Also you can put a "div" function inside a "div" function, and a "article" function inside an "article" function. Also, of course, you can put an "article" function inside a "div" function and vice-versa.

[@nomadshiba]

i always use grid or flex and use block and inline-block, inline and stuff, basically the default displays only if im actually rendering an article, a document etc basically what html has been made for originally other than that everything is always inside a grid mostly flex is only useful if stuff has dynamic different sizes, based on content, such as navigation menu, tags list, or such

[@Fleshbits1]

Do you have a video that explains how you are seeing your results, editing css, etc. for noobs? Looks like you have the css open as a tab in vscode and the page open in something else? It refreshes automatically?

[@christopherportorreal]

@kevinPowell I have a problem when starting to design. I'm practicing with Frontend Mentor, and the designs are normally created with Mobile: 375px and 1440px widths. How should I start setting the right space to work? Should I use max-width or just the width at the beginning?

for the even columns with flex:1, can we use a wrapper in each element, and the wrapper child content put the padding? Ill test it

[@okthatsnice]

at 5:08 why are the .wrapper element's horizontal margins inside of the parent (header) whereas the h1's top margin is outside of its parent / applied to the parent (the header element)?

[@sanfords]

Can't seem to pay for the demystified course. The Pay Now button never gets enabled even though I entered everything.

[@josephlivengood4508]

Is this why you use a reset CSS to remove all the default margin from the h tags? Just curious @7:40

[@someone5502]

I wish I could use grid and more up to date features but I always have to cater for IE, and older browsers, as most sites I cater to at work are business sites. I love web development but I hate how it takes years before I can actually start using certain things.
