Is there a way to alter the background image of the logo specifically for mobile device viewing?

Here is a snippet of my HTML code: 

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{{ route('home') }}">
        <img src="{{ asset('assets/images/logo-school-icon.png') }}" alt="icon" width="50" height="50">
        <img class="logo-school" src="{{ asset('assets/images/logo-school.png') }}" alt="logo">
    </a>
</nav>

This is how my CSS looks like: 

@media (max-width: 530px) {
    .navbar-brand .logo-school {
        background-image:url('assets/images/logo-school-mobile.png');
    }
}

When accessed from desktop, the images displayed are logo-school-icon.png and logo-school.png.

On the other hand, if accessed from mobile devices, I want to show logo-school-icon.png and replace logo-school.png with logo-school-mobile.png.

I have attempted this approach, but it is not working as expected. When accessed from a mobile device, both images (logo-school.png and logo-school-mobile.png) still appear instead of just logo-school-icon.png and logo-school-mobile.png.

Can someone provide me with a solution to solve this issue?

Note: I am still looking for a resolution to this problem. Please make sure to understand my question properly before providing an answer. I appreciate any responses with a demo (HTML+CSS). Thank you.

Answer №1

To manage how images are displayed based on resolution, one approach is to add a specific class to each image tag for manipulation. Alternatively, you can utilize the following method:

HTML

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{{ route('home') }}">
        <img src="https://example.com/image1.jpg" alt="icon" width="150" height="150">
        <img class="logo-school" src="https://example.com/image2.jpg" alt="logo"  width="300" height="300">
    </a>
</nav>

CSS

@media (max-width:530px) {
  nav a img:nth-child(1) {
    display: none;
  }
}

@media (min-width:530px) {
  nav a img:nth-child(2) {
    display: none;
  }
}

Remember to adjust the image sources accordingly.

Answer №2

To ensure a smooth transition between desktop and mobile views, it is recommended to assign a specific classname to the <img> element that will only be visible on desktop. For mobile view, set this classname's CSS property to display: none;.

@media (max-width: 530px) {
    .navbar-brand img.logo-school-desktop {
        display: none;
    }
    .navbar-brand .logo-school {
        background-image:url('assets/images/logo-school-mobile.png');
    }
}
<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{{ route('home') }}">
        <img class="logo-school-desktop" src="{{ asset('assets/images/logo-school-icon.png') }}" alt="icon" width="50" height="50">
        <img class="logo-school" src="{{ asset('assets/images/logo-school.png') }}" alt="logo">
    </a>
</nav>

Answer №3

To achieve this, you can utilize a media query.

Update: I now comprehend the issue at hand. This update should address your concern. I included a third img tag that will be displayed or hidden based on the screen size using media queries.

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{{ route('home') }}">
        <img class="logo-school-icon" src="{{ asset('assets/images/logo-school-icon.png') }}" alt="icon" width="50" height="50">
        <img class="logo-school" src="{{ asset('assets/images/logo-school.png') }}" alt="logo">
       <img class="logo-school-mobile" src="{{ asset('assets/images/logo-school-mobile.png') }}" alt="logo">
    </a>
</nav>

@media (min-width: 320px) and (max-width: 530px) {

   .logo-school-icon {
       display: block; // Add !important if needed to override a style
    }

  .logo-school {
           display: none; // Add !important if needed to override a style
        }

  .logo-school-mobile {
           display: block; // Add !important if needed to override a style
        }

}

@media (min-width: 531px) {

   .logo-school-icon {
       display: block; // Add !important if needed to override a style
    }

  .logo-school {
           display: block; // Add !important if needed to override a style
        }

  .logo-school-mobile {
           display: none; // Add !important if needed to override a style
        }

}

Your question has been updated, and it's much clearer now. I've got a code snippet that works for me:

HTML

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{{ route('home') }}">
      <img class="logo-school" width="300" height="300">
    </a>
</nav>

CSS

.logo-school {
  display: block;
  background-size: contain;
}

@media (max-width: 530px) {
    .navbar-brand .logo-school {
        background-image:url('https://99designs-blog.imgix.net/wp-content/uploads/2017/04/attachment_79503506-e1491509305138.jpg?auto=format&q=60&fit=max&w=930');
    }
}

@media (min-width: 530px) {
    .navbar-brand .logo-school {
        background-image:url('https://www.schoolbrandingmatters.co.nz/wp-content/uploads/2018/11/Whitau-School-Logo-2.jpg');
    }
}

You can customize the background URLs with your own images.
