making the arrows more prominent?

You can use media query in your ninja-slider.css file to make a separate copy for the navigation control styles (suppose you have a larger navs-for-mobile.png image):

Enlarging the click arrows on a slider for mobile devices typically involves adding custom CSS styles to override the default styles. To do this, you'll need to inspect the HTML and CSS of your slider to identify the appropriate elements and classes to target. Here are some general steps to follow:

1. Inspect the Elements: Use your browser's developer tools (usually accessible by right-clicking on the slider and selecting "Inspect" or pressing F12) to inspect the HTML structure of the slider and find the specific elements for the click arrows.

2. Identify the CSS Classes: Look for the CSS classes or IDs associated with the arrows. These classes are used to style the arrows.

3. Add Custom CSS: Once you've identified the classes, you can add custom CSS styles to enlarge the arrows. Here's an example of what the CSS might look like:

cssCopy code
/* Increase the size of the arrows on mobile devices */
@media (max-width: 768px) {
  .slider-arrow {
    font-size: 24px; /* Adjust the font size to make the arrows larger */
    /* Add any other styling as needed */
  }
}

In this example, we're using a media query to target screens with a maximum width of 768 pixels, which typically corresponds to mobile devices. Adjust the font-size property to make the arrows larger, and you can also apply additional styling as needed.

4. Include the CSS: Make sure to include this custom CSS in your website or application. You can do this by adding it to your site's existing CSS file or by including it in a <style> tag within your HTML document.

5. Test and Adjust: After adding the custom CSS, four in a row test your slider on mobile devices to ensure that the arrows are now the desired size. You may need to fine-tune the styles until you achieve the desired appearance.

Keep in mind that the specific CSS classes and structure of your slider may vary depending on the slider plugin or library you are using. Be sure to adapt the above steps to match the structure and classes of your particular slider. If you provide more details about the slider you're using, I can offer more specific guidance.
