Whenever you upgrade something and it fails your blog gets stuck in maintenance mode.

Now I like that the message shows while you are upgrading but if it is not successful you have a bit of a problem.you can see a message as “Briefly unavailable for scheduled maintenance.check back in a minute.”

To Fix this,access your server through FileZilla.Normally .maintenance file will be in a hidden format.so make it visible and remove it.
For that
In FileZilla

Goto Server->Force Showing hidden Files.You can see .maintenace file in your root folder.just delete and reload the page.problem solved.

Single and Double Quotes
Use single and double quotes when appropriate. If you’re not evaluating anything in the string, use single quotes. You should almost never have to escape HTML quotes in a string, because you can just alternate your quoting style, like so:

echo '<a href="/static/link" title="Yeah yeah!">Link name</a>';
echo "<a href='$link' title='$linktitle'>$linkname</a>";

An exception to this is JavaScript, which sometimes requires double or single quotes. Text that goes into attributes should be run through esc_attr() so that single or double quotes do not end the attribute value and invalidate the HTML and cause a security issue. See Data Validation for further details.
Indentation

Your indentation should always reflect logical structure. Use real tabs and not spaces, as this allows the most flexibility across clients.

Exception: if you have a block of code that would be more readable if things aligned, use spaces:

[tab]$foo   = 'somevalue1';
[tab]$foo2  = 'somevalue2';
[tab]$foo34 = 'somevalue3';
[tab]$foo5  = 'somevalue4';

To style every image on your site to look a particular way, look for or add the CSS selector for the image tag. Then add your styles to the tag. For instance, let’s say that you want a black border around all of your images and you want space between the border and the image, as well as the appropriate spacing around the image and the text.

Open style.css,

img {
     margin: 5px;
     padding: 10px;
     border: solid #000000 1px
}

Inline styling of images

There are times when you just want one or two images on your site to look different from the rest. This technique is called inline styles. It applies the CSS styles directly to the image itself. For example, say you want to have an image isolated against a black background to call attention to it.

<img src="schogini.gif" alt="Schogini Systems" style="padding:25px; background: #000000; border: none" />

Pages  are for creating contents such as  Help,  About us, Contact us etc. Pages live outside of the normal blog chronology, and are often used to present information about yourself or your site that is somehow timeless information that is always applicable. You can use Pages to organize and manage any amount of content. The examples of common pages include Copyright, Legal Information, Reprint Permissions, Company Information, and Accessibility Statement.

Pages can be organized into pages and subpages.Pages can use different templates.

To create a new Page, log in to your WordPress installation with sufficient admin privileges to create new articles. Select the Administation->Pages->Add New option to begin writing a new Page.

Open header.php template file and include your javascript file inside the head tag. The code for including javascript file is :
