| 17 | <P>The Base element allows the URL of the document itself to be set, to help browsers in situations where the document may be read out of context. It is especially useful in allowing browsers to determine any partial URL's, or relative paths that may be specified (for example, in <CODE><A HREF="../Anchors/anchor.htm"><A HREF></A></CODE> elements, or paths pointing to <CODE><A HREF="../Media_Embedding/img.htm"><IMG SRC=...></A></CODE> (images). The <CODE><BASE></CODE> Element should appear within the bounds of the <CODE><A HREF="head.htm"><HEAD></A></CODE> element.
|
|---|
| 18 | <P>Where the base address is not specified, the HTML user agent uses the URL it used to access the document to resolve any relative URLs.
|
|---|
| 19 | <P>The Base element uses the <SPAN CLASS="attr">HREF</SPAN> attribute, which identifies the URL, which should be a fully qualified URL

| 42 | The <CODE>CLASS</CODE> attribute is used to specify the <CODE><BASE></CODE> as using a particular style sheet class. See the <A HREF="../Style_Sheets/ov.htm" TITLE="View the Style Sheets overview">Style Sheets</A> topic for more information.

|

| 45 | The <CODE>ID</CODE> attribute can be used to either reference a unique style sheet identifier, or to provide a unique name for the <CODE><BASE></CODE> element for scripting purposes. Any <CODE><BASE></CODE> element with an <CODE>ID</CODE> attribute can be directly manipulated in script by referencing its <CODE>ID</CODE> attribute, rather than working through the <A HREF="../Scripting_Reference/allcol.htm" TITLE="View the All collection topic">All collection</A> to determine the element.

|

| 48 | The <CODE>LANG</CODE> attribute can be used to specify what language the <CODE><BASE></CODE> element is using. It accepts any valid ISO standard language abbreviation (for example <CODE>"en"</CODE> for English, <CODE>"de"</CODE> for German etc.) For more details, see the <A HREF="../Document_Localisation/ov.htm" TITLE="View the HTML localisation topic">Document Localisation</A> section for more details.

| 51 | The <STRONG>Internet Explorer</STRONG> 4.0 (and above) specific <CODE>TITLE</CODE> attribute is used for informational purposes. As the <CODE><BASE></CODE> element doesn't directly affect the display of a document, no ToolTip is presented when using the <CODE>TITLE</CODE> attribute (as with other elements).
