IE sometimes gets confused when you name a class or an id using a tag name.

Note that some search engines can not search certain sites unless the robots.txt file is present.

You are never going to exactly fill a screen with an image. There are too many differences in screen resolution, aspect ratio, and browser configurations among different computers for you to expect...

There is no way to fill the viewport exactly that works on all computers, browsers, window sizes, screen resolutions, and screen aspect ratios. Do not attempt to do this. It is not intended to be...

This is a homework assignment. Do not give the answer.

Negative numbers are not part of the W3C definition for margin. Browsers go into quirks mode when they encounter them.

Note that it is NOT necessary to make a separate style sheet for IE. I have...

First of all, 0px is an invalid style attribute. Some browsers throw out all styles where a unit of measure is attached to a 0 value.

Second, as long as you define all of your sizes in pixels, you...

The background image url belongs in a style for the body tag.

I am not sure what you mean to make the image transparent. The background is supposed to be on the bottom, so there should be nothing...

The problem is that vertical centering can not be done in a way that works on all computers, browsers, screen resolutions, screen aspect ratios, browser configurations, and current browser window...

- Alignment is not inherited from div to table. You need to apply the style to the td tags.

- The php script may be overriding the style.

- If there is any syntax error in the style, the entire...

We have too much government. They should not have control of your site.

You will either have to use .gif instead of .jpg, and set a transparent color, or match the background color in the background of the image.

I don't like curved corners either.

You have to set your body overflow style to scroll.

That dotted line indicates that the picture has the focus. That is a windows function. It is supposed to be there.

Neither 0 px nor 0px is a valid code.

0 px has a space in it, which makes it two different items.

0px does not work on some browsers, and causes the entire style to be eliminated. Those...

If you want the table to be the width of the screen, use:

width: 100%;


Remember that different computers have different screen widths in pixels.

You might have to tell FF where the port is.

Go into Tools/Options and check the settings.

What kind of connection do you have?

Is that bot-ulism?

Something is disabled in his browser.

There is a setting on some browsers to print just the text, to save paper.

No, they are not. Many people with visual problems use 800X600 to make the text large enough to read.

I don't click on links with IP addresses in them. They can go to malware sites.

Check these:

- Don't put size styles (width, height), and surrounding styles (margin, border, padding) on the...

No. This would require a script.

First of all, I wish the hover attribute had never been invented. I hate pages that change when you move the mouse without clicking. They make the page not accessible to the disabled.

Your problem...

You can't do it that way. You have to make an image with a transparent color in it.

Usually this must be a .gif image. You create the image in an image editor, using a specific color you do not...

You can't reference an address on your own disk drive and expect that image to work when the page is uploaded. You have done this in your body css.

The only way I know to compatibly include a font the user does not have installed is to create an image file containing the text in the font you want, and put the image on the website.

There is a separate w3c frameset doctype if you want frames in xhtml.

Frames are deprecated in the strict xhtml doctype.

If you are expecting the background color to fill the div around the edge of the square image, you need some padding.

If you expect the background color to fill in around an irregularly shaped...

Never put size styles (width, height) and surround styles (margin, border, padding) in the same style or on the same web page tag.

Instead, nest two box objects. Put the size styles on one box...

Is your image larger than the viewport?

You don't. The user does this.

The user right-clicks on the image, and selects Save Image As from the menu.

It would be a security violation if a web page did this on its own.

Just leave the divs transparent. As long as you don't specify a background, they will show the background under them.

Be careful putting images under text. Many people have trouble reading that.

Stop the bots, and you are no longer indexed on search engines.

He was just struck by lightning. :icon_mrgreen:

It usually works. But you can not guarantee that it will work every time. When it doesn't work, the user can refresh the page, and hopefully the path will not go though an old routing computer the...

0px is not a valid style. Use just 0 for all 0 values. Do not attach a unit of measure. It causes some browsers to throw away the style.

It could be that the server doesn't know how to use a .pptx file yet. Or it might not know to serve some auxillary file.

Did you use some built in file in the presentation, but forget to upload...

Don't use pixels to define sizes. This introduces incompatibilities that depend on screen resolution.

A cracker may be trying to overload the site to exploit vulnerability.
