Responsive Design Techniques

For each section in this document, complete the challenge as described.

Make the <body> of this document be 800px wide and 90% the width of the viewport, whichever is smaller. Center the body on the page no matter how wide the viewport is.

Make the background-color of this document to #eaf6ff when the viewport width is 640px or more.

Make the <h1> on this page have a font-size of 1.5rem when the viewport width is below 500px, and 2.5rem when the viewport width is above 640px .

Turn the following list into a grid of boxes that wrap horizontally (side-by-side until they run out of room and wrap to the next line). Make each <aside> 170px wide, with a 10px margin. Set the font-size for the boxes to be 0.8rem. Be sure to remove the bullets associated with the <li> tags, and remove the default padding-left on the <ul>.

As above, make a grid of boxes that wrap horizontally. This time, give each <li> a width of 100%. When the viewport width is greater than 480px, make each <li> be 50% wide. If the viewport is greater than 640px, make each <li> be 25% wide. The grid should be 1-across at small widths, 2-across at medium widths, and 4-across and large widths. Don't set a width on the <aside> elements, but be sure they have a 10% margin.

Now, set the <ul> to have a margin of -10px left and right, 1rem top and bottom. What happens?
