Your `main` element should have at least two `section` elements within it showcasing the event features. 1. Your `section` elements each should have an `h2` within them. 1. Your body should have a top and bottom padding of `50px`. 1. Your body should have a top and bottom margin of `0`, and a left and right margin that centers itself. 1. Your body should have a width set relative to the width of the viewport. 1. Your body should use the `calc` function to set its `min-height` property to 100% of the viewport's height minus all padding applied to the top and bottom of the body. 1. You should have at least one `hr` within your flyer. 1. You should set the `width` of all `hr` and `section` elements to a percent value relative to its parent. **Note:** Be sure to link your stylesheet in your HTML and apply your CSS.
