Clearing a float container without source markup

Clearing a float container without source markup
(This clearing technique was developed by Tony Aslett, of csscreator.com. The earliest known mention of the basic :after idea is found here.) Notice as of March 4th, 2008: The article you are reading is getting a bit old and much new information on the subject of clearing has appeared since it was written. You may find this newer article very interesting. Clearing Floats The Old Fashioned Way When a float is contained within a container box that has a visible border or background, that float does not automatically force the container's bottom edge down as the float is made taller. This float-enclosing behavior in IE can also be 'toggled' off again just by hovering of links within the container, if that hovering alters either the link background or one of several other CSS properties. The W3C suggests placing a "cleared" element last in the container box, which is then recognized by the container height, forcing the container to enclose the float above that cleared element too. <div><!

CSS - Clearing floats Page last changed today A common problem with float-based layouts is that the floats' container doesn't want to stretch up to accomodate the floats. If you want to add, say, a border around all floats (ie. a border around the container) you'll have to command the browsers somehow to stretch up the container all the way. Let's try it.

Step by step CSS float tutorial Floatutorial takes you through the basics of floating elements such as images, drop caps, next and back buttons, image galleries, inline lists and multi-column layouts. General info Tutorial 1. Floating an image to the right Downloading a Complete Picasa Web Album (Without Installing Picasa) Google's Picasa Web Album supports downloading an entire album, however, it requires the Picasa software to do so. Bummer if you are on a Mac, or don't want to (or can't) install Picasa on your computer. There's another tutorial online that suggests using a Greasemonkey script to surface the download links, then use the DownThemAll Firefox extension to grab the links. Sadly, the Greasemonkey script in question stopped working after a recent code change on the picasa website. I was able to easily fix it, but due to the lack of an open license, I am unable to share the script with you :( However, I found an alternative solution: The album's RSS feed!

Contained Floats, enclosing floats with pure CSS known as the clearfix technique Author: Tony Aslett First created 8-May-2004 There is a large and growing movement by web developers and designers towards web standards. Part of that movement focuses on clean mark-up, which has many long term benefits such as easier maintenance, lighter pages and better support by browsers of the future. One thing that has bugged me was the need to add clearing elements to the mark-up to keep a container wrapped around a floated element. Most people use a division, horizontal rule or a break and set it to clear both to keep the container around the float.

How to: CSS Large Background Since I posted the huge collection of Large Background Websites, I received several email requests on how to make a large background site with CSS.

Understanding Floats A mini-tutorial on how the CSS float and clear properties work, and how to use them in your page. Note: all examples in this tutorial use inline-CSS to illustrate what is going on. You should not do this in your pages, but should instead abstract the styles out into a separate style sheet. For more information, see the "Separate Style from Content" tip in another tutorial of mine, "How to Develop with CSS".

All About Floats By Chris Coyier On What is "Float"? Float is a CSS positioning property. To understand its purpose and origin, we can look to print design. In a print layout, images may be set into the page such that text wraps around them as needed. This is commonly and appropriately called "text wrap". About rel="canonical" - Webmaster Tools Help This article describes how you can use canonical URLs to improve link and ranking signals for content available through multiple URL structures or via syndication. In the world of content management and online shopping systems, it's common for the same content to be accessed through multiple URLs. With content syndication, it's also easy for content to be distributed to different URLs and domains entirely. For example: While these systems make it more convenient to develop and distribute content, they cause some challenges when people use search engines to reach your page.

The Clearfix: Force an Element To Self-Clear its Children This will do you fine these days (IE 8 and up): Apply it to any parent element in which you need to clear the floats. For example: You would use this instead of clearing the float with something like <br style="clear: both;" /> at the bottom of the parent (easy to forget, not handleable right in CSS, non-semantic) or using something like overflow: hidden; on the parent (you don't always want to hide overflow). Now for a bit of history! This was the original popular version, designed to support browsers as far back as it possibly could: Objects, Images, and Applets in HTML documents 13.1 Introduction to objects, images, and applets HTML's multimedia features allow authors to include images, applets (programs that are automatically downloaded and run on the user's machine), video clips, and other HTML documents in their pages. For example, to include a PNG image in a document, authors may write: <BODY><P>Here's a closeup of the Grand Canyon: <OBJECT data="canyon.png" type="image/png"> This is a <EM>closeup</EM> of the Grand Canyon.
