Learn CSS Positioning in Ten Steps. 1. position:static The default positioning for all elements is position:static, which means the element is not positioned and occurs where it normally would in the document. Normally you wouldn't specify this unless you needed to override a positioning that had been previously set. 2. position:relative If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document. Let's move div-1 down 20 pixels, and to the left 40 pixels: Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space.
It appears that position:relative is not very useful, but it will perform an important task later in this tutorial. 3. position:absolute When you specify position:absolute, the element is removed from the document and placed exactly where you tell it to go. Let's move div-1a to the top right of the page: What I really want is to position div-1a relative to div-1. Footnotes 10. Understanding z-index. How to use it The six color boxes (A, a, B, b, C, c) are "draggable", which means you can use your mouse to position them anywhere in the page.The input elements in the colored fieldsets below let you set z-index and position values for each one of these six boxes. These fieldsets are color coded, which means a fieldset's background color matches the background color of the box it is supposed to style. Set and reset Things to keep in mind: The z-index value is set once the input field loses focus or if the user presses the enter key while the caret is in that field, so you need to type some value and then TAB out of the box (or click outside of that box) for the new value to "kick-in".Dragging a box makes its position relative (note that the relevant radio button is "checked" only after that box is "dropped").The "set" and "reset" links above allow you to remove the negative margin applied by default to box A, B, C and also let you revert the document to its original state.

I have extended the Crossfader functionality by adding four new public methods: StopFade() -- Pause the progression by stopping Crossfader StartFade() -- Resume the progression by starting Crossfader SetFade(newFadeTime) -- Change the duration of the fade transition (in seconds) SetDelay(newDelayBetweenFades) -- Change the length of time between transitions (in seconds) By providing a user interface to these four methods, you can give the user control over the slideshow experience -- stop it, start it, speed it up, or slow it down.

CSS: A tribute to selectors | And all that Malarkey. CSS: A tribute to selectors I wanted to learn more about CSS attribute selectors. Two things happened on Friday which prompted me to talk about CSS attribute selectors. The first was an email plopping into my inbox, The second was working on a new web site with the mighty Brothercake. Scanning through the CSS he had written, like Alex, I was intrigued by, So, wanting to find out about these types of selectors I did a bit of reading around, but many of the explanations were a tad complicated. So I made some experiments of my own and thought I'd share them.
Before we start, if you're reading this with Internet Explorer, go and amuse yourself for a few minutes, as attribute selectors won't work in the world's most popular (sic) browser. Attribute selectors Attribute selectors allow you to target an element based upon its 'attribute'. The first example targets any element which has a specific attribute, for example all anchors which have a title attribute. Moving on Your thoughts? Replies.
CSS Rounded Corners 'Roundup' 4Google + Note: This post is continually updated as I come across new techniques. This collection of techniques to create boxes with rounded corners using CSS has become quite popular. The problem now is there are so many choices it's hard to know which one to choose. To that end I've provided some more information about each method in order to help people choose which best fits their needs. Some of these techniques use CSS and one or more background images, some use CSS, JavaScript and no images, and a couple use only CSS — no images or JavaScript required (more markup is needed though). Not Sure Which One to Use? There are so many different techniques now, it really depends on your individual requirements and preferences; particularly whether you want to use a JavaScript-based technique or not. Try out a few methods and see if there's one that fits. Click on a column heading to sort the table by that column.
