Marquee validating w3c
Once it has disappeared off the other side, it starts again (assuming more than one iteration has been specified).This is often referred to as "scrolling" (eg, scrolling text, scrolling images, etc). As with any CSS property, if a browser doesn't support a proprietary extension, it will simply ignore it.Although HTML and CSS validation icons no longer appear at the bottom of every modern-facing website, there is still a general sentiment that validation is necessary.Can we satisfy standards compliance without the need for validation, or, alternatively, is there a better approach to validation? Validation was created, in part, to drum up interest for standards compliance after newfangled browsers like Netscape and Internet Explorer started extending the capabilities of HTML in the early 1990s. Many rebuffed these additions as going beyond the original intent of the language, to provide document structure, not influence stylistic choices. Our framework is tested in almost every perceivable browser, and battle-tested daily by our 20-plus team of engineers and designers, and yet we still don't meet validation, even though it renders well in most every browser.This made us wonder if validation is still relevant?
Also, marquees have since been dropped from the CSS3 specification.Also, scrolling text too fast can make it unreadable to some people, particularly those with visual impairments. To combat this, most client-side scripting allows marquees to be programmed to stop when the mouse is over them.Unlike its blinking counterpart, the marquee element has several attributes that can be used to control and adjust the appearance of the marquee.The marquee tag is a non-standard HTML element which causes text to scroll up, down, left or right automatically. As with the blink element, marquee-tagged images or text are not always completely visible on rendered pages, making printing such pages an inefficient (if not impossible) task; typically multiple attempts are required to capture all text that could be displayed where messages scroll or blink.The tag was first introduced in early versions of Microsoft's Internet Explorer, and was compared to Netscape's blink element, as a proprietary non-standard extension to the HTML standard with usability problems. The version of marquee makes text jitter back and forth but does not obscure any part of it if scrolling widths are set correctly.
