    Thanks a lot bro,
    I was always looking for something like this to test immediately on production, and it has always been there.
    This is incredible.

    Umar, thank you for this. Any serious developer who doesn't subscribe to your lessons is a fart. So much goodness in one video it's hard to understate how outstanding this is. Thank you for sharing this and all of your lessons!

    3:05 The MDN website itself is also an excellent example of using the "font-display: swap" property. You can see it really clearly if you step frame by frame through the video with "," and "." as the website loads.

    Amazing job Umar! I love the voice, humor, and the flow of your content. I thought I was pretty good with Chrome dev tools but I learned something new in every minute of this video.

    This is great Umar. I was just working on a competitive analysis to compare what important elements are loading by 1st meaningful paint, your screenshot tip just made this project A LOT easier. Another great vid, I'm so going to reference this one! The 10:38 mark, hahahaha

      I know....I saw that and didn't believe what was happening. It took me back to my old sublime text days before VS Code came and forced that persky Shift in between.

    Finally, the hack of "window.onbeforeunload = function() { return '';}" is coming to an end for me :D

    Local Override seems to be functioning a bit differently on my chrome build. The overrides are being applied after the initial stylesheets. So for example, "color: red" would only be applied half a second after the white text shows. Because of this, "font-display:swap" also didn't work because of how the local overrides are being applied after the initial stylesheets loaded.
    Regardless of whatever this is(bug/my own stupidity/ etc), this is an awesome video!! Time to dive into your whole series!!

    This is really great! Just one thing I'd like to point out that I didn't notice you mention, this isn't in stable Chrome yet. It was slated for release in Chrome 64, and is even displayed in the "What New" tab in DevTools, however it was pulled at the last minute. So I assume you're using a Canary build of Chrome to be able to use the feature. Chrome 65 is supposed to have it. Thanks for the great example, is going to help massively when I can finally use it! (I'm on Linux machine, where Canary isn't available :( )

      I'm on Ubuntu and using local overrides for a while now. The package is "google-chrome-beta" there is even another one called "google-chrome-unstable" which is one version ahead of beta

    display-font ***** Great property - Didn't know of its existence

    @AlexanderWigmore Před 6 lety

    Great vid-what happens to the local override file if the live CSS changes and they haven't used a unique query string? Does the local override forever take charge until you manually pull the latest changes?
    Also, here's the font-display caniuse for anyone that's interested: caniuse.com/#feat=css-font-rendering-controls

    The internet of 5 years ago wasnt slow enought for this to make any difference...
    guess how it will be 5 years from now when this css atribute may be supported by half of the browsers
