Change Number Input Arrows

### 1. **Using Pseudo-Elements (Webkit Browsers)**
You can target the spinner buttons for WebKit-based browsers (like Chrome and Edge) with the following CSS:

input[type="number"]::-webkit-inner-spin-button {
    color: red; /* Change the color */
}

input[type="number"]::-webkit-outer-spin-button {
    color: red; /* Change the color */
}

> Note: The `color` property may not work in all cases. Use `appearance: none` and replace the spinner buttons with custom designs if needed.

### 2. **Hiding Default Arrows and Creating Custom Spinners**
If changing the arrow color isn't supported by your browser, hide the default spinner and use custom buttons:

input[type="number"] {
    -webkit-appearance: none;
    -moz-appearance: textfield; /* For Firefox */
    appearance: none;
    border: 1px solid #ccc;
    padding: 8px;
}

.custom-spinner {
    display: flex;
    align-items: center;
}

.custom-spinner button {
    background-color: #f0f0f0;
    border: 1px solid #ccc;
    color: red; /* Custom arrow color */
    padding: 5px;
    cursor: pointer;
}

HTML:

<div class="custom-spinner">
    <button onclick="decrement()">-</button>
    <input type="number" id="numberInput" value="0">
    <button onclick="increment()">+</button>
</div>

JavaScript:

function increment() {
    const input = document.getElementById('numberInput');
    input.stepUp();
}

function decrement() {
    const input = document.getElementById('numberInput');
    input.stepDown();
}

### 3. **Using JavaScript Libraries**
For more advanced customizations, you can use libraries like:

– [jQuery Spinner](https://jqueryui.com/spinner/)
– [Input Number Customizer Plugins](https://plugins.jquery.com/)

This approach ensures consistent cross-browser support and eliminates reliance on browser-specific features.

### **CSS Styling for Browser-Supported Customization**

#### WebKit Browsers (Chrome, Edge, Safari):
You can target the spinner arrows using the `::-webkit-inner-spin-button` and `::-webkit-outer-spin-button` pseudo-elements. However, you can't directly change their color, but you can hide them or adjust their appearance with properties like `background-color` or `border`.

input[type="number"]::-webkit-inner-spin-button {
    background-color: lightgray; /* Change background of spinner buttons */
    border: none; /* Optional: remove borders */
}

input[type="number"]::-webkit-outer-spin-button {
    background-color: lightgray; /* Same styling as above */
    border: none;
}

#### Firefox:
Firefox does not support direct styling of the spinner buttons. You can hide them using `appearance: textfield`:

input[type="number"] {
    -moz-appearance: textfield; /* Hides arrows in Firefox */
}

#### Cross-Browser Styling:
To remove the arrows across all browsers:

input[type="number"] {
    -webkit-appearance: none; /* For Chrome, Safari, Edge */
    -moz-appearance: textfield; /* For Firefox */
    appearance: none; /* Standardized property */
}

However, hiding the arrows doesn't let you change their color. Instead, you might consider adding a `box-shadow` or background styles to emulate the appearance of custom arrows.

### **Why Color Styling Might Not Work**
Browsers tightly control native form elements for accessibility reasons, so the arrow color can't be directly modified. If styling is critical, consider creating custom input designs or adding a feature request to the browser teams via their development channels.
