Home / CSS3 Previews / Multiple Backgrounds with CSS3 CSS3 allows web designers to specify multiple background images for box elements, using nothing more than a simple comma-separated list. Browser support for multiple backgrounds is relatively widespread with Mozilla Firefox (3.6+), Safari/Chrome (1.0/1.3+), Opera (10.5+) and even Internet Explorer (9.0+) all implementing the feature. Here’s a basic example: This box has two background images, the first a sheep (aligned to the bottom and center) and the second a grass and sky background (aligned to the top-left corner). Here’s the code for this: How it Works Multiple background images can be specified using either the individual background properties or the background shorthand property. Specifying multiple backgrounds using the individual background properties Multiple background images are specified using a comma-separated list of values for the background-image property, with each value generating a separate ‘background layer’. = | none

15.1 Introduction Setting font properties will be among the most common uses of style sheets. Unfortunately, there exists no well-defined and universally accepted taxonomy for classifying fonts, and terms that apply to one font family may not be appropriate for others. E.g., 'italic' is commonly used to label slanted text, but slanted text may also be labeled as being Oblique, Slanted, Incline, Cursive or Kursiv. 15.2 Font matching algorithm Because there is no accepted, universal taxonomy of font properties, matching of properties to font faces must be done carefully. The User Agent makes (or accesses) a database of relevant CSS 2.1 properties of all the fonts of which the UA is aware. (The above algorithm can be optimized to avoid having to revisit the CSS 2.1 properties for each character.) The per-property matching rules from (2) above are as follows: 'font-style' is tried first. 15.3 Font family: the 'font-family' property There are two types of font family names: serif sans-serif cursive

6 CSS Tricks to Align Content Vertically
Let’s talk about vertical alignment in CSS, or to be more precise how it is not doable. CSS has not yet provided an official way to center content vertically within its container. It’s a problem that probably has frustrated web developers everywhere. But not to fear, in this post, we’re going to run by you a few tricks that can help you imitate the effect. These tricks may however have limitations, and you may have to use more than one trick to complete the illusion. Recommended Reading: How To Obtain Equal Column Height With CSS 1. The first trick we are going to see here uses the position property. We will first set the position of the container element to relative, then we set the child element position to absolute. To align it vertically, move the child element position from the top, by half of the container’s height, and pull it up by half of the child element width. 2. CSS3 Transform has made it easy to put content at the center. 3. 4. 5. 6.
CSS - jquery - Transitions
This post will introduce you to CSS transitions and CSS transforms: the CSS power couple. When used together, these properties allow you to create simple animations and add valuable interaction and visual feedback for your users. Just remember when adding any kind of movement to your project to keep it simple, subtle, and consistent. The movement you create should convey meaning, always enhancing, not distracting from the interaction for your users. So what are transforms and transitions? At their most basic level, transforms move or change the appearance of an element, while transitions make the element smoothly and gradually change from one state to another. CSS transitions: an introduction Let’s start with CSS transitions. Hover below: In this post I’ll be using transitions in conjunction with transforms. There are two properties that are required in order for the transition to take effect: 1. transition-property 2. transition-duration Note: Transition Shorthand CSS syntax examples: scale skew

HTML Event Attributes
curriculum/README.md at master · dev-academy-programme/curriculum
DOM Events are sent to notify code of interesting things that have taken place. Each event is represented by an object which is based on the Event interface, and may have additional custom fields and/or functions used to get additional information about what happened. Events can represent everything from basic user interactions to automated notifications of things happening in the rendering model. This article offers a list of events that can be sent; some are standard events defined in official specifications, while others are events used internally by specific browsers; for example, Mozilla-specific events are listed so that add-ons can use them to interact with the browser. Standard events These events are defined in official Web specifications, and should be common across browsers. Non-standard events Mozilla-specific events Note: those events are never exposed to web content and can only be used in chrome content context. XUL events Add-on-specific events Developer tool-specific events
As a web developer, you will probably take advantage of a whole range of different tags when putting together your next site build. Chances are high that you are already well versed in some of the commonly known tags introduced in HTML5 such as <article>, <header> and <footer>, however you might not be aware of some of the lesser known / edge case tags you could be taking advantage of. Some of these tags are either brand new in HTML5 or have been repurposed from the HTML4 specification. For each tag, we will go through what the W3C specification says and apply a practical example to showcase how you might use it. A Quick Word on Interpretation While the W3C specifications are great for conceptual overviews, sometimes they lack practical examples, which makes it challenging when searching for the best way to use some of these tags. You might have used some of these tags before — perhaps just not in the same way. 1 – Contextual Highlighting With <mark> “Relevance’ is hard to describe.

Hover To View Hidden Text Overflow
When text must stay on one line, but there is not enough room for it all, here is a solution. A mouse hover can display text that doesn't otherwise fit on the line. Sometimes, for design or other reasons, a line of text must remain as one line. It may not break into multiple lines. The solution is pure CSS. The CSS Declarations The CSS declaration white-space:nowrap; keeps all text on one line. If there is more text than fits on the line, it will extend past the right side of the div or other container. One way to correct it is to reduce the font size of the text until it fits within the container. Another way to correct it is to use the CSS declaration overflow:hidden; to clip any text that extends past the right side of the container. At this point, the class for the container with the one long line of text has these two CSS declarations: white-space:nowrap; overflow:hidden; Optionally, use the CSS declaration text-overflow:ellipsis; to print an elipsis where some of the text is clipped.
Color Picker — HTML Color Codes
Analogous Complementary Triadic Tetradic Analogous Neutral Shades Tints Tones Color Picker Use the color picker by clicking and dragging your cursor inside the picker area to highlight a color on the right. Color Harmonies Color harmonies are particularly pleasing combinations of two or more colors derived from their relationship on a color wheel. Complementary colors Colors that are directly opposite one another on the color wheel are known as complementary colors. Triadic colors Triadic harmonies consist of three colors equidistant from one another on the color wheel. Tetradic colors Tetradic color harmonies are formed by two sets of complementary colors 60 degrees apart on the color wheel. Analogous colors Analogous harmonies are created by selecting the colors directly adjacent to a chosen color. Neutral colors Neutral schemes, like analogous harmonies, are formed by taking the colors on either side of a chosen color but at half the distance. Color Shades, Tints and Tones

The float property is a valuable and powerful asset to any web designer/developer working with HTML and CSS. Tragically, it can also cause frustration and confusion if you don’t fully understand how it works. Article Continues Below Also, in the past, it’s been linked to some pretty nasty browser bugs so it’s normal to get nervous about using the float property in your CSS rule sets. We see floats in the print world every time we pick up a magazine article with an image on the left or right with text flowing nicely around it. The definition#section1 Let’s start with the definition of a float. A float is a box that is shifted to the left or right on the current line. The float property has four values that we can apply to it: left, right, inherit, and none. Here is a simple example like the magazine reference above, Example A and the corresponding markup: How floats behave#section2 Nothing too complex, but still pretty cool right? Let’s look at a few more examples. In the clear#section3
