Here's the solution to exercise.
Number five, we inserted a device called Container into the eight a.m. page we associated to it 90
percent of the width of the content of the page.
Therefore, in the browser preview, this will fill 90 percent of the page.
After that, we define a max height of the header.
That is a hundred pixels.
We modify the color of the background by inserting a shadow black given by all these three in this hexadecimal
encoding.
And we apply the Tahoma font to stylesheet.
Finally, we inserted a padding into the container in header and future.
The result is this.
As you see, we detached from the top and from the left.
The contents.
We still did not have such a distance.
And now the page appears with this background with a shade of black, which is lighter than before.
