XHTML Tutorial 3 Test Notes

 

There are 16 basic color names supported by HTML and XHTML.

 

Any color can be thought of as a combination of three primary colors: red, green, and blue.

By varying the intensity of each primary color, you can create almost any color and any shade of color that you want.

 

Each color on the Web is represented by a triplet of numbers, called a(n) hex triplet.

 

In the RGB system, the absence of color is assigned the number 0.

 

In the RGB system, the intensity of colors is assigned a number from 0 to 255.

 

White has an RGB triplet of (255, 255, 255).

 

Originally, HTML required that color values be entered as hexadecimals.

 

In the hexadecimal system, 16 is expressed as 10.

 

In the hexadecimal system, 21 is expressed as 15.

 

Which of the following is a specific font? Arial

 

If you use a hexadecimal value for a color, you preface the hexadecimal string with a(n) pound symbol.

 

A(n) pixel represents a single dot on the output device.

 

The amount of space between pairs of letters is referred to as the kerning.

 

The two image formats supported by most Web browsers are GIF and JPEG.

 

GIF is the most commonly used image format on the Web.

 

GIF files are limited to displaying 256 colors.

 

Clip art images, line art and logos are all uses of the GIF format.

 

Animated GIFs are an effective way to compose slide shows or to simulate motion.

 

Like the JPEG format, PNG supports the full 16.7 million colors of the color palette.

 

JPEG images can use 16.7 million colors.

 

To use a single image to access multiple targets, you must set up hotspots within the image.

 

Hotspots are defined through the use of image maps.

 

A(n) image map lists the position of all hotspots within a particular image.

 

Client-side and server-side are types of image maps.
