          </button>
        </div>
      </div>

Can anyone give me some reference to make it or the best practice to make it?

Apply the gradient with something like bg-gradient-to-b from-purple-500 to-purple-500/25:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-html -->

<script src="https://cdn.tailwindcss.com"></script>

<nav class="nav_dropshadow flex flex-wrap items-center justify-between p-3 drop-shadow-xl" style="background-color: #2F3030">
  <div class="mr-96 flex flex-shrink-0 items-center text-white bg-gradient-to-b from-purple-500 to-purple-500/25">
    <a class="font-coolvetica pl-3 font-bold text-white text-4xl">ZeroHero</a>
  </div>
  <div class="flex w-auto flex-grow items-center">
    <div class="text-xl/8 text-white flex-grow">
      <a href="#" class="text-white-200 mr-4 inline-block"> Dashboard </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Games </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Statistics </a>
    </div>
    <div class="pr-3">
      <button class="font-roboto inline-flex items-center rounded-md border-0 px-7 py-3 text-sm font-bold text-black" style="background-color: #00F0FF">Connect Wallet</button>
    </div>
  </div>
</nav>

<!-- end snippet -->

Remove the padding from the <nav>, and apply the effects to the child elements, so that the gradient can be edge-to-edge:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-html -->

<script src="https://cdn.tailwindcss.com"></script>

<nav class="nav_dropshadow flex flex-wrap items-center justify-between drop-shadow-xl" style="background-color: #2F3030">
  <div class="mr-96 flex flex-shrink-0 items-center text-white bg-gradient-to-b from-purple-500 to-purple-500/25 self-stretch">
    <a class="font-coolvetica pl-3 font-bold text-white text-4xl">ZeroHero</a>
  </div>
  <div class="flex w-auto flex-grow items-center p-3">
    <div class="text-xl/8 text-white flex-grow">
      <a href="#" class="text-white-200 mr-4 inline-block"> Dashboard </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Games </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Statistics </a>
    </div>
    <div class="pr-3">
      <button class="font-roboto inline-flex items-center rounded-md border-0 px-7 py-3 text-sm font-bold text-black" style="background-color: #00F0FF">Connect Wallet</button>
    </div>
  </div>
</nav>

<!-- end snippet -->

Add some padding to the right, for the spacing after the logo:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-html -->

<script src="https://cdn.tailwindcss.com"></script>

<nav class="nav_dropshadow flex flex-wrap items-center justify-between drop-shadow-xl" style="background-color: #2F3030">
  <div class="mr-56 flex flex-shrink-0 items-center text-white bg-gradient-to-b from-purple-500 to-purple-500/25 self-stretch pr-40">
    <a class="font-coolvetica pl-3 font-bold text-white text-4xl">ZeroHero</a>
  </div>
  <div class="flex w-auto flex-grow items-center p-3">
    <div class="text-xl/8 text-white flex-grow">
      <a href="#" class="text-white-200 mr-4 inline-block"> Dashboard </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Games </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Statistics </a>
    </div>
    <div class="pr-3">
      <button class="font-roboto inline-flex items-center rounded-md border-0 px-7 py-3 text-sm font-bold text-black" style="background-color: #00F0FF">Connect Wallet</button>
    </div>
  </div>
</nav>

<!-- end snippet -->

Apply a clip-path, something like polygon(0 0, 100% 0,calc(100% - theme(spacing.8)) 100%, 0 100%) for the angled edge, using an arbitrary property class:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-html -->

<script src="https://cdn.tailwindcss.com"></script>

<nav class="nav_dropshadow flex flex-wrap items-center justify-between drop-shadow-xl" style="background-color: #2F3030">
  <div class="mr-56 flex flex-shrink-0 items-center text-white bg-gradient-to-b from-purple-500 to-purple-500/25 self-stretch pr-40 [clip-path:polygon(0_0,100%_0,calc(100%-theme(spacing.8))_100%,0_100%)]">
    <a class="font-coolvetica pl-3 font-bold text-white text-4xl">ZeroHero</a>
  </div>
  <div class="flex w-auto flex-grow items-center p-3">
    <div class="text-xl/8 text-white flex-grow">
      <a href="#" class="text-white-200 mr-4 inline-block"> Dashboard </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Games </a>
      <a href="#" class="text-white-200 mr-4 inline-block"> Statistics </a>
    </div>
    <div class="pr-3">
      <button class="font-roboto inline-flex items-center rounded-md border-0 px-7 py-3 text-sm font-bold text-black" style="background-color: #00F0FF">Connect Wallet</button>
    </div>
  </div>
</nav>

<!-- end snippet -->
