Attributes are use to guide web browser to render an HTML element. As an HTML tag is processed, the looks to these attributes as guides for the construction of web elements. Without any attribute values specified, the browser will render the element using the default setting(s) (usually very boring).
The title attribute titles an HTML element and adds a tiny text pop-up to any HTML element, offering your web viewers a tool-tip mechanism where information can be found or where a better description of an HTML element can be seen.
Much like the tool tips found in word processing programs, this attribute can add spice to any page while offering the user priceless interactivity. As the mouse hovers over the element, a tool tip is displayed, giving the viewer just one extra piece of information.
<h2 title="Hello There!">Titled Heading Tag</h2>
If you wish to change the horizontal alignment of your elements, you may do so using the align attribute. It allows you to align things left, right, or center. By default, most elements are automatically aligned left, unless otherwise specified.
HTML Align Attribute:
<h2 align="center">Centered Heading</h2>
