至少有两种方法可以做到这一点：

选项1：使用Bootstrap类text-center
选项2：在<embed>的父类上使用引导类d-flex justify-content-center

请参阅下面的片段。

<!DOCTYPE html>
<html lang="en">

<body>
    <div class="container text-center">
        <embed class="logo " src="https://www.google.com.br/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png" alt="Logo">
