Could I suggest adding a few more meta tags to your HTML head:

  <meta charset="UTF-8" />
  <meta name="description" content="..." />
  <meta name="keywords" content="..." />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <meta name="author" content="..." />

(Fill in the '...' bits 👍)
