• 开始抽签

<script setup>
import FenDang from "@/components/chouqian/FenDang.vue";
import {ref} from "vue";let isShowFenDang = ref(false)
function showFenDang(){isShowFenDang.value = true;
}</script><template><div class="flex-container"><h2>2024年世界杯预选赛亚洲区抽签仪式</h2><img src="@/assets/fendang.png" alt="Logo" class="logo"><button class="start-button" @click="showFenDang">开始抽签</button><FenDang v-if="isShowFenDang"/></div>
</template><style scoped>
.flex-container {display: flex;flex-direction: column;align-items: center;justify-content: center;text-align: center; 
}.logo {width: 600px;
}.start-button {/* 根据需要设置合适的宽度和高度 */width: 100px; height: 40px; background-color: #4CAF50;border: none;color: white; padding: 10px 20px;text-align: center; text-decoration: none;font-size: 14px; margin: 4px 2px;cursor: pointer; border-radius: 8px; transition: background-color 0.3s; 
}.start-button:hover {background-color: #45a049;
}
</style>
