Create a Card Component

The heading area of the Card component is empty, this is because it didn’t receive the header prop. The header prop expects another component, the CardHeader.

1. Import the CardHeader.

   TypeScript Copy

   import { Card, CardHeader } from "@ui5/webcomponents-react";

2. Add the CardHeader component to your Card and give it a title by setting the titleText prop:

   TypeScript Copy

   <div>
     <Card header={<CardHeader titleText="Card" />}>
       This is the content area of the Card
     </Card>
   </div>

3. Our template applies the SAP defined font-family for all texts that don’t implement font-family themselves. (see index.css file) To enable this on a single text without using CSS, you can use the Text component. Let’s wrap the text content of the Card inside the Text component:

   TypeScript Copy

   import { Card, CardHeader, Text } from "@ui5/webcomponents-react";

   TypeScript Copy

   <div>
     <Card header={<CardHeader titleText="Card" />}>
       <Text>This is the content area of the Card</Text>
     </Card>
   </div>

In this step, we will only apply inline-styling. You can also style your component using CSS (modules), but this and many more information regarding the styling approach of UI5 Web Components (for React) will be covered in chapter six of the tutorial series.

The Card now spreads across the whole screen, this behavior is intended, so it takes up the whole space of its container.

1. To restrict the width of the Card, add the style prop.

   TypeScript Copy

   <Card header={<CardHeader titleText="Card" />} style={{ width: "300px" }}>
     <Text>This is the content area of the Card</Text>
   </Card>

   

2. The content of the card is way too close to the border of the Card, so a padding is needed. You can define your own spacing, or use the standard SAP spacing variables. In this example we’re using one of the global CSS Variables from the theming-base-content repo, which are already included when using UI5 Web Components.

   The CSS var in question is --sapContent_Space_S (1rem) and we’re going to apply it via inline-style again:

   TypeScript Copy

    <Text style={{padding: "var(--sapContent_Space_S)"}}>
      This is the content area of the Card
    </Text>

   Hereby you get a standardized content-padding.

After this step MyApp.tsx should look like this:

import { Card, CardHeader, Text } from "@ui5/webcomponents-react";

export function MyApp() {
  return (
    <div>
      <Card header={<CardHeader titleText="Card" />} style={{ width: "300px" }}>
        <Text style={{ padding: "var(--sapContent_Space_S)" }}>
          This is the content area of the Card
        </Text>
      </Card>
    </div>
  );
}

And your application like this:

1. The Card header can also be interactive, to enable this set interactive to true.

   TypeScript Copy

   <Card
     header={<CardHeader titleText="Card" interactive />}
     ...
   </Card>

   We didn’t pass a value to interactive, because it defaults to true if the value is omitted.

   When you now click or focus the header, the appropriate styles are applied, so users know they can interact with it.

2. To make the header react to a click (or SPACE/ENTER press), add a function as value to the onClick prop.

   TypeScript Copy

   <Card
     header={
       <CardHeader
         titleText="Card"
         interactive
         onClick={handleHeaderClick}
       />
     }
   >
     ...
   </Card>

3. Now, add the callback function right in the beginning of the component (definition function):

   TypeScript Copy

   export function MyApp() {
     const handleHeaderClick = () => {
       alert("Header clicked");
   };
   ...

The file should now look like this:

import { Card, CardHeader, Text } from "@ui5/webcomponents-react";

export function MyApp() {
  const handleHeaderClick = () => {
    alert("Header clicked");
  };
  return (
    <div>
      <Card
        header={
          <CardHeader
            titleText="Card"
            interactive
            onClick={handleHeaderClick}
          />
        }
        style={{ width: "300px" }}
      >
        <Text style={{ padding: "var(--sapContent_Space_S)" }}>
          This is the content area of the Card
        </Text>
      </Card>
    </div>
  );
}

Now the header opens an alert box on click.
