There are many different ways to use the web besides a mouse and a pair of eyes. Users navigate for example with a keyboard only or with their voice.
All the functionality, including menus, links and forms should work using a keyboard only. This is essential for all assistive technology to work properly. The only way to test this, at the moment, is manually. The best time to test this is during development.
How to keyboard test:
Tab through your pages, links and forms to do the following tests:
Confirm that all links can be reached and activated via keyboard, including any in dropdown submenus.
Confirm that all links get a visible focus indicator (e.g., a border highlight).
Confirm that all form input fields and buttons can be accessed and used via keyboard.
Confirm that all interactions, buttons, and other controls can be triggered via keyboard — any action you can complete with a mouse must also be performable via keyboard.
Confirm that focus doesn’t move in unexpected ways around the page.
Confirm that using shift+tab to move backwards works as well.
The HTML <blockquote> Element (or HTML Block Quotation Element) indicates that the enclosed text is an extended quotation. Usually, this is rendered visually by indentation (see Notes for how to change it). A URL for the source of the quotation may be given using the cite attribute, while a text representation of the source can be given using the <cite> element.

These tests are a big deal, but this tag is no longer supported in HTML5.
Cite Tag
“Code is poetry.” —Automattic
Code Tag
This tag styles blocks of code. .post-title {
margin: 0 0 5px;
font-weight: bold;
font-size: 38px;
line-height: 1.2;
and here's a line of some really, really, really, really long text, just to see how it is handled and to find out how it overflows;
}
You will learn later on in these tests that word-wrap: break-word; will be your best friend.
Delete Tag
This tag will let you strike out text, but this tag is recommended supported in HTML5 (use the <s> instead).
Emphasize Tag
The emphasize tag should italicizetext.
Horizontal Rule Tag
This sentence is following a <hr /> tag.
Insert Tag
This tag should denote inserted text.
Keyboard Tag
This scarcely known tag emulates keyboard text, which is usually styled like the <code> tag.
Preformatted Tag
This tag is for preserving whitespace as typed, such as in poetry or ASCII art.
The Road Not Taken
Robert Frost
Two roads diverged in a yellow wood,
And sorry I could not travel both (\_/)
And be one traveler, long I stood (='.'=)
And looked down one as far as I could (")_(")
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim, |\_/|
Because it was grassy and wanted wear; / @ @ \
Though as for that the passing there ( > º < )
Had worn them really about the same, `>>x<<´
/ O \
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference.
and here's a line of some really, really, really, really long text, just to see how it is handled and to find out how it overflows;
Welcome to image alignment! The best way to demonstrate the ebb and flow of the various image positioning options is to nestle them snuggly among an ocean of words. Grab a paddle and let’s get started.
On the topic of alignment, it should be noted that users can choose from the options of None, Left, Right, and Center. In addition, they also get the options of Thumbnail, Medium, Large & Fullsize. Be sure to try this page in RTL mode and it should look the same as LTR.
The image above happens to be centered.
The rest of this paragraph is filler for the sake of seeing the text wrap around the 150×150 image, which is left aligned.
As you can see the should be some space above, below, and to the right of the image. The text should not be creeping on the image. Creeping is just not right. Images need breathing room too. Let them speak like you words. Let them do their jobs without any hassle from the text. In about one more sentence here, we’ll see that the text moves from the right of the image down below the image in seamless transition. Again, letting the do it’s thang. Mission accomplished!
And now for a massively large image. It also has no alignment.
The image above, though 1200px wide, should not overflow the content area. It should remain contained with no visible disruption to the flow of content.
And we try the large image again, with the center alignment since that sometimes is a problem. The image above, though 1200px wide, should not overflow the content area. It should remain contained with no visible disruption to the flow of content.
And now we’re going to shift things to the right align. Again, there should be plenty of room above, below, and to the left of the image. Just look at him there… Hey guy! Way to rock that right side. I don’t care what the left aligned image says, you look great. Don’t let anyone else tell you differently.
In just a bit here, you should see the text start to wrap below the right aligned image and settle in nicely. There should still be plenty of room and everything should be sitting pretty. Yeah… Just like that. It never felt so good to be right.
And just when you thought we were done, we’re going to do them all over again with captions!
The image above happens to be centered. The caption also has a link in it, just to see if it does anything funky.
Bigger caption than the image usually is.

Comment for massive image for your eyeballs.
The image above, though 1200px wide, should not overflow the content area. It should remain contained with no visible disruption to the flow of content. This massive image is centered.
And again with the big image centered. The image above, though 1200px wide, should not overflow the content area. It should remain contained with no visible disruption to the flow of content.
Feels good to be right all the time.

And that’s a wrap, yo! You survived the tumultuous waters of alignment. Image alignment achievement unlocked! One last thing: The last item in this post’s content is a thumbnail floated right. Make sure any elements after the content are clearing properly.
