} 

@-moz-keyframes bounce-up { /* Firefox */

  60% {transform: translateY(-12.5px);}  
}

/* Animations for stats section */
.animate--fade-in-left {
  animation: fadein-left 2s;
  -moz-animation: fadein-left 2s; /* Firefox */
  -webkit-animation: fadein-left 2s; /* Safari and Chrome */
  -o-animation: fadein-left 2s; /* Opera */
}

The CSS code above defines a number of keyframe animations for a website. The animations include bounce-1, bounce-up, and fade-in-left. These animations can be applied to elements on a website using the animation property and giving the name of the keyframe animation as the value, along with any additional animation properties such as duration and delay. For example, to apply the bounce-up animation to an element with the class my-element, the following code could be used:

Additionally, the code defines some classes that can be applied to elements to trigger the animations, such as animate—bounce-up and animate—fade-in-left. These classes can be added to an element along with the animation property to trigger the animation. For example:

<div class="my-element animate--bounce-up">
  This element will bounce up when the page loads.
</div>

Note that in order for these animations to work properly, the website must also include the necessary vendor prefixes for different browsers, as shown in the code above.

}

The code above is a React component that renders a command bar at the top of the page. The command bar has a button that allows the user to toggle between light and dark themes for the page. The command bar also has several other buttons for performing various actions.

The component uses the useContext hook to get the current theme from the Context object and to dispatch actions that update the theme. The useEffect hook is used to set the initial theme to dark when the component is first rendered.

The CustomButton and CustomMenuItem components are custom renderers for the command bar buttons and menu items, respectively. These custom renderers allow the developer to control the styles of the buttons and menu items.

The command bar is rendered using the CommandBar component from the office-ui-fabric-react library. This component allows the developer to specify the items that appear in the command bar and their behavior. The items that appear in the overflow menu (the menu that appears when there are too many items to fit in the command bar) are determined automatically by the CommandBar component.

Overall, this component provides a user-friendly way to access common actions and to toggle between light and dark themes for the page.

  )
}

The code above is a React component that renders a row with two columns. The first column contains a large DocumentCard component with an image. The second column contains two smaller DocumentCard components with icons.

The DocumentCard components are from the office-ui-fabric-react library. These components are used to display documents or other information in a visually appealing way. The DocumentCard component can display a preview image, title, and other details about the document.

The component uses the DocumentCard component from the office-ui-fabric-react library to render the card. It sets the height and imageFit properties on the DocumentCardImage component to control the size and fit of the preview image. The DocumentCardTitle component is used to display the title and secondary title of the document.

Overall, this component provides a user-friendly way to display information about documents or other items in a visually appealing way.
