#42: All About Floats Screencast

Even more-so than z-index (which we covered a few weeks ago), the float property is known to cause episodes of hair-pulling and monitor-punching. It seems simple enough in theory, but there are plenty of quirks to watch out for. We go from start to finish in this screencast defining what float is, how it works, how and why to clear them, and some browser differences.

    You can also fix the IE6 double-margin bug by applying “display: inline;” to the respective floated element.. much easier and way cleaner than a javascript-solution (also, it’ll work for people who have javascript disabled).

    And no.. I have no idea why this works, but then again, I have no idea why IE6 doesn’t render it properly in the first place, so there you go.

    Nice, Helps a lot! If you want another idea how about tables, I know they are classic and outdated, but how about for organizing huge amounts of data?

    What do you tell your clients?
    “sorry i currently don’t support the worlds most distributed browser “

    Nice tutorial Chris. I heard last week i think, that Firefox now had 20% of the browser market, which is great news and hopefully we can get rid of IE altogether!! Just wondered Chris on the last part with the article, it shows in a diagram with the side bar being pushed down in IE6, what is the font that is used where it says “Push Down”??

    Hey Chris,

    Been enjoying your screencasts since you started them and I have learned a ton.

    I took HTML and CSS in school, yet I’ve found that these web tutorials are so much more efficient and knowledgable.

    Keep up the good work!

    Nacho, easy clearing is a great method, if you know how to use it and it is not as inconsistent as you might think. Chris should have mention it anyway ;)

    Re: 6:40 into the screencast: One of the easiest reasons to understand why a containing element "collapses" when floats are inside, is so that multiple paragraphs will wrap around a really tall floated image that's contained inside the first paragraph tag.

    Actually, IE6 is only used by approximately 20%, according to w3c. Another 26% user IE7, and a growing portion (44%) use Firefox.

    It all really boils down to who the target user is. IE6 is only a piece of the Microsoft family, a lot of people forget that IE7 comprises a little more than half of the total number of IE users.

    Hi everyone :-)
    Great Vid !

    I was wondering if anyone can help me with something….
    Im a mac user, and i have no means of buying a pc, but i want to be able to check up on my websites on IE 6-7 etc…..

    I see on the video that it's possible… can anyone tell me how this is done?
    Do I have to run Parallels to do so? (Or something similar?)
    I currently use the browsershots.org website, but i would like to be able to see what I do on IE….

    Thanks so much for any help you guys can provide.. :-)

    Great video, as always. I love that you cover the more complicated stuff to the basics.

    I like to view videos on my iphone and would love to see a iphone feed of the videos. The only requirements are that the resolution is max 640×480 and it uses h264 or MP4 for video codec and aac or mp3 as audio codec.

    Either way, keep making your videos, they are really useful!

    I was just explaining clearing floats to a designer I work with. This is a great help!

    A way that I like to have a parent container wrap around floated elements is the float the container. I then set the width to 100% or to the fixed width that the container should hold, thus not allowing any elements below the container to wrap.

    Great vid Chris! Although, I have to admit I was a little distracted at ~1:26. You opened Firefox and I saw "…en nerd" in your google search and my mind began to wander. :^)

    Ha! I believe I was searching for what the internet considered the difference to be between a "geek" and a "nerd". I'm doing a blog design for a client with the word "geek" in the title, I wanted to maybe play off that a little.

    @Garro- In the vid Chris is using VMWare which will cost you about $80 plus you will have to buy a copy of Windows. Personally I have an old Sony laptop running XP (and Ubuntu) and that's where I do all my testing for the dreaded IE.

    Hey, Codeweavers has a great solution that's about US$40 bucks that allows you to run some MS stuff without buying windows. Works great, that's how we check IE6. Just google it and it will come up.

    Has anyone tried the Float (Nearly) Everything method? You can read more about it over at orderedlist.com I prefer it over the overflow method.

    THANK YOU!!!

    I had not touched a website I had been working on for ages and the layout was killing me. I had always wondered why FireBug would only highlight a small portion of the div when I hovered over it and did not extend the way it should.

    It’s really hard to understand this concept, but visually seeing happening will definitely make it easier to remember in the future. Thanks again!! :-)
