Step 5

Add the below code in App.css 

.App {
    text - align: center;
}.App - logo {
    height: 40 vmin;
    pointer - events: none;
}
@media(prefers - reduced - motion: no - preference) {
    .App - logo {
        animation: App - logo - spin infinite 20 s linear;
    }
}.App - header {
    background - color: #282c34;
  min-height: 100vh;
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
  font-size: calc(10px + 2vmin);
  color: white;
}

.App-link {
  color: # 61 dafb;
}
@keyframes App - logo - spin {
        from {
            transform: rotate(0 deg);
        }
        to {
            transform: rotate(360 deg);
        }
    }
    /* GalleriaAdvancedDemo.css */

    }.galleria - demo.custom - galleria.custom - galleria - footer {
        display: flex;
        align - items: center;
        background - color: rgba(0, 0, 0, .9);
        color: #fff;
    }.galleria - demo.custom - galleria.custom - galleria - footer > button {

    }.galleria - demo.custom - galleria.title - container > span {
        font - size: 0.9 rem;
        padding - left: 0.829 rem;
    }.galleria - demo.custom - galleria.title - container > span.title {
        font - weight: bold;
    }

Step 6

Add the following code in package.json,

import datas from './Photos.json';
export class PhotoService {
    getImages() {
        const results1 = [];
        datas.map((datas) => {
            results1.push(datas)
        });
        return results1;
    }
}

Step 9

Run the following command

npm i 
npm start
