1. Components Not Initializing

Understanding the Issue

Materialize CSS components such as modals, dropdowns, or carousels do not function as expected.

Root Causes

  • Missing or incorrect initialization of Materialize components.
  • Conflicts with other JavaScript libraries.
  • Incorrect DOM structure preventing component binding.

Fix

Ensure Materialize JavaScript is properly included:

<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>

Initialize components correctly in JavaScript:

document.addEventListener("DOMContentLoaded", function() {
    M.AutoInit();
});

Manually initialize specific components if needed:

var elems = document.querySelectorAll(".modal");
var instances = M.Modal.init(elems);

2. Layout and Alignment Issues

Understanding the Issue

UI components do not align properly, break on different screen sizes, or behave unexpectedly.

Root Causes

  • Incorrect usage of Materialize grid classes.
  • Conflicting CSS rules overriding Materialize styles.
  • Viewport meta tag missing, affecting responsive behavior.

Fix

Ensure the viewport meta tag is included in the HTML:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Use Materialize grid classes correctly:

<div class="row">
    <div class="col s12 m6 l4">Content Here</div>
</div>

Inspect conflicting CSS rules and override carefully:

.custom-class {
    display: flex !important;
}

3. JavaScript Conflicts

Understanding the Issue

Materialize JavaScript functions do not work due to conflicts with other frameworks or libraries.

Root Causes

  • jQuery and Materialize both trying to manipulate the DOM.
  • Multiple JavaScript libraries using the same global variables.
  • Improper loading order of scripts.

Fix

Ensure proper script loading order:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>

Use jQuery noConflict mode if needed:

var $jq = jQuery.noConflict();

Check for duplicate event bindings:

$(document).off("click", ".dropdown-trigger").on("click", ".dropdown-trigger", function() {
    M.Dropdown.init(this);
});

4. Performance Issues

Understanding the Issue

Materialize CSS applications experience slow performance, animations lag, or page rendering is delayed.

Root Causes

  • Excessive use of animations and JavaScript-heavy components.
  • Large images slowing down rendering.
  • Too many Materialize instances running simultaneously.

Fix

Disable excessive animations:

M.toast({html: "Hello!", displayLength: 2000});

Optimize images using lazy loading:

<img src="/image.jpg" loading="lazy" />

Manually destroy unused instances:

var instance = M.Carousel.getInstance(element);
instance.destroy();

5. Compatibility Problems

Understanding the Issue

Materialize CSS does not work correctly across different browsers or mobile devices.

Root Causes

  • CSS inconsistencies between browsers.
  • JavaScript features not supported in older browsers.
  • Viewport settings affecting responsiveness.

Fix

Ensure cross-browser compatibility:

@supports (display: grid) {
    .custom-class { display: grid; }
}

Use polyfills for unsupported JavaScript features:

<script src="https://cdn.jsdelivr.net/npm/@babel/polyfill"></script>

Test responsiveness using Materialize breakpoints:

@media only screen and (max-width: 600px) {
    .mobile-adjust { font-size: 14px; }
}

Conclusion

Materialize CSS is a robust front-end framework, but troubleshooting component initialization, layout misalignment, JavaScript conflicts, performance issues, and browser compatibility problems is essential for smooth development. By ensuring proper script loading, using responsive design principles, and optimizing animations, developers can create high-performance applications with Materialize CSS.

FAQs
