Let me break down each of the properties and their meanings:

 

1. .container: This is a CSS class selector. It is used to target HTML elements with the class attribute set to "container." In your HTML, you would apply this class to the element you want to style with these CSS rules.

2. background-image: This property sets the background image of the container. In this case, the URL points to an image file located at '/resource/1676670272000/orman'. This image will be displayed as the background of the container.

3. background-color: This property sets the background color of the container. It uses RGBA (Red, Green, Blue, Alpha) values to specify the color. In your code, the color is a light blue with an alpha (transparency) value of 0.8, which makes it slightly transparent.

4. padding: This property adds space inside the container. In this case, 1rem (which stands for "1 root em," a relative unit of measurement). It creates padding on all sides of the container, separating its content from the container's edges.

5. margin: This property sets the margin around the container. Similar to padding, it also uses 1rem to create a margin of 1 root em on all sides of the container. Margin separates the container from other elements on the page.

6. border-radius: This property rounds the corners of the container, giving it rounded edges. A value of 0.5rem is used, which makes the corners slightly curved.

7. box-shadow: This property adds a shadow to the container. It takes four values: horizontal offset, vertical offset, blur radius, and color. In this case:

   • Horizontal offset: 0px (no horizontal offset)

   • Vertical offset: 2px (a 2-pixel shadow below the container)

   • Blur radius: 5px (the shadow is slightly blurred)

   • Color: rgba(0, 0, 0, 0.3) (a black shadow with 30% opacity)
