Here's the code I'm working with:
<nav class="navbar navbar-expand-lg navbar-md-dark navbar-lg-light" style="background-color: #11100b;" id="nav-mob">
<div class="container">
<a class="navbar-brand " href="#">
<img src="./logo dark.png" id="logochange" width="150" alt="LOGO">
</a>
<button class="navbar-toggler " type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon">
</span>
</button>
</div>
</nav>
While the hamburger sign is clickable, it's not visible against the dark background. How can I change its color or make it brighter?
