.:1:. What are the common attributes of <span>?As the span element is generic, it has no attributes of its own. Instead, it uses the attributes that are common to virtually every HTML element: id, class, style, title, lang, dir, onclick, ondblclick, onmousedown, onmouseup, onmouseover, onmousemove, onmouseout, onkeypress, onkeydown, and onkeyup.
.:2:. Is it possible to align the content in a <span> tag without placing it in a div?Inline, non-replaced elements like span have no concept of width; the box that they create wraps tightly around the content (http://www.w3.org/TR/REC-CSS2/visuren.html#inline-formatting) (see the example near the end). As such, alignment is equally meaningless. Text alignment only applies to block-level elements, like p, div, and several others.
You can style an inline element to format itself like a block-level element, and therefore give it width and align its contents, but that may, or may not, be the best solution - it depends on what exactly you're trying to do.
I could not find enough accurate information on the correct attributes/properties.The HTML specification (http://www.w3.org/TR/html4/) provides all the information you need (http://www.w3.org/TR/html4/struct/global.html#h-7.5.4). The box at the top is taken from the DTD: the grammar that defines a form of HTML (the different forms are Strict, Transitional, and Frameset). In this case, the attribute list declaration (<!ATTLIST ...>) uses an entity, attrs, to define the supported attributes. This entity expands to three other entities: coreattrs, i18n, and events. If you follow the links to these definitions, you'll see they add up to the list I gave at the start of this post.
.:3:. If there is a better way than to use the <span> tag, please What is it? :o Maybe, but you haven't clearly stated what you want to do, but merely alluded to positioning some text (and there are numerous ways to do that). Please show an example. What would be really nice is a link to what your markup is now, and a small image showing how you want it to look.
<span> is eqivalent to <a> except that it cannot support an href attribute.An a element defines a link, an anchor, or both (depending on its attributes). A span element defines nothing intrinsically as it's a generic element. They are hardly equivalent - a bad choice of words. Furthermore, there are many attributes that apply to a elements, but not to spans: charset, type, name, href, hreflang, rel, rev, accesskey, shape, coords, tabindex, focus, and blur.
