Asets the width of page elements as a percent of the available screen width.

a.) fixed layout
b.) fluid layout
c.) standard layout
d.) stationary layout

B) Fluid Layout

Explanation:

Fluid layout on page will resizes itself whenever window size changes. We need to define page area as percentage rather then fix pixel width.

For Example

If user want to fill the content area with 480px, by using fluid layout user can create a layout to fill 40% of the web page area. By using percentage, content can extend or shrink with respect to the screen size.

Example in StyleSheet (Css) format

Fixed Layout

.content { width: 480px; }

Fluid Layout

.content { width: 40%; }

yes we can change both the color of the value of a cell as well as background color of a cell at the same time .

as we know that excel sheet consists of columns and rows.

and intersection of column and row is called cell.

we can change color of the cell and background of the cell at the same time.

hence the statement that

can a person change color of the cell and background of the cell at the same time is true.

i guess the correct option is letter a.

use contrasting font sizes, but the same font style
