Problems
This line enable URL Rewriting . It must be enabled via the RewriteEngine directive! and if your .htaccess file is going to use rewrite rules, you should always include this line. Otherwise, you can’t be sure if its enabled or not. The string “on” is case insensitive.
<h1>
Generally this serves as the main heading on the page. It is often the same as the title, but it does not have to be. Normally, this would be the first element inside the BODY.
Use HTML headings for headings only. Don't use headings to make text BIG or bold.
Search engines use your headings to index the structure and content of your web pages.
Users skim your pages by its headings. It is important to use headings to show the document structure.
h1 headings should be main headings, followed by h2 headings, then the less important h3, and so on.

<h2> - <h6>
These are sub headings. You should step through these in sequence. If you need to give subheadings to anything after the main heading, then you should use H2. If you need to create subsections within these sections, they should use H3, etc.
<p>
This denotes a paragraph, just like a normal paragraph in a document. In theory you can omit the closing tag, but I advise you to always include it.
<pre>
This denotes a block of preformatted text. In general you should avoid this, but it can be useful for a few things, such as displaying a block of source code, or displaying a verse of a poem. Inside a PRE block, all spaces, tabs and linebreaks are preserved, and will be displayed on the page.
<address>
This denotes a special type of paragraph that contains contact information, such as a postal or email address.
<blockquote>
This is for use when quoting text from other pages, books, documents, speeches, etc. It cannot contain text directly, and should instead contain other block level elements. They can then contain the quoted text. It is also possible to use the cite attribute to give the URL of a page where the quote was taken from, but no current browsers have a useful way to use that.
Inline elements
<em>
Indicates emphasised text - most browsers render this in italics.
<p>This is an <em>important</em> word.</p>
<strong>
Indicates strongly emphasised text - most browsers render this in bold.
<li>This is <strong>very important</strong>.</li>
<sub>
Indicates subscript text - most browsers render this in a small font, positioned near the bottom of normal text.
<h3>Oxygen is O<sub>2</sub></h3>
<sup>
Indicates superscript text - most browsers render this in a small font, positioned near the top of normal text.
<p>This is the 2<sup>nd</sup> street.</p>
<code>
Used for a short piece of programming code that is used as part of a sentence - most browsers render this in a monospace font.
<dd>This is done using the <code>x++</code> operator.</dd>
<samp>
Used for a sample output from a program, script, or form - most browsers render this in a monospace font.
<p>This script would output <samp>Hello world</samp></p>
<kbd>
Used to indicate a key combination or keyboard shortcut - most browsers render this in a monospace font.
<td>Press <kbd>Ctrl+C</kbd> to copy</td>
<var>
Used to indicate a program or code variable - most browsers render this in italics.
<li>Here, we can use the <var>window.document</var> object</li>
<dfn>
Used to indicate that the word(s) inside the DFN element are being defined in the current paragraph (or whatever the parent block element is) - most browsers render this in italics.
<p>A <dfn>heading</dfn> is a title for a section of a document.</p>
<ins>
Indicates that the inserted text has been inserted into the document after its initial creation - generally used along with the DATETIME attribute to say when the change occurred. It is also possible to use the cite attribute to give the URL of a page with more details about the change, but no current browsers have a useful way to use that. Most browsers render this with an underline or in italics. The underline can make it easy to confuse with links, but most browser have still adopted the underline convention.
<p>This is <ins datetime="2006-02-22T17:43:32GMT">not</ins> the only time this has happened.</p>
<del>
Indicates that the inserted text has been deleted - generally used along with the DATETIME attribute to say when the change occurred - most browsers render this with a line through it.
<p>There are <del datetime="2006-02-22T17:43:32GMT">loads of</del> options.</p>
<abbr> and <acronym>
Used to indicate that the word or letters are a contracted form of more words. There is a lot of confusion over where each of these should be used, but in general, the ABBR indicates that the letters are not spoken as a word (such as HTTP), whereas ACRONYM indicates that the contents are spoken as a word (such as such as laser). Future HTML versions will only have the ABBR element, so you may want to avoid the ACRONYM element altogether, and use only the ABBR element for all abbreviations and acronyms. The title attribute is used to give the full expanded form of the abbreviated word. Most browsers display this with a dotted bottom border. Internet Explorer 6- does not recognise either of these elements. Internet Explorer 7+ recognises both, but does not apply any styles to them by default.
<dd>This uses the <abbr title="HyperText Transfer Protocol">HTTP</abbr> protocol.</dd>
<q>
This is for use when quoting text from other pages, books, documents, speeches, etc. In some browsers it will automatically be given quotes at each end. It is also possible to use the cite attribute to give the URL of a page where the quote was taken from, but no current browsers have a useful way to use that.
<p>According to him <q cite="http://example.com/">there is no spoon</q>.</p>
<cite>
Used to give the title of a cited source - most browsers render this in italics.
<li>More information can be found in <cite>A Tale of Two Cities</cite>.</li>
<b>, <i>, <big>, <small>, <tt>
These elements make text bold, italic, big, small, and fixed width font respectively. HTML transitional also allows a few others such as STRIKE or S (line-through), U (underline), and FONT (font families and colours). I recommend that you avoid these, mainly because there is almost always something much more appropriate.
