How can I ensure that the logo on the navbar is responsive?

Question

How can I ensure that the logo on the navbar is responsive?

Hey there! Check out the website I've crafted using bootstrap 4. I'm facing a major problem with the logo, as it remains the same size across all devices.

I attempted to include the img-fluid class, but when added, the logo shrinks so drastically on mobile phones that it appears like a tiny speck. Hence, I removed this class. Currently, on mobile, the hamburger icon has moved to the second line while the first line of the navbar displays the 310 px logo incompletely. I wish to maintain the spacing between the navbar elements as it is now, but suspect the issue may stem from my css:

.navbar .navbar-brand {
padding: 5px 200px;
}


.navbar-nav>li {
padding-left: 5px;
padding-right: 5px;
}

.navbar-nav>li {
margin-left: 5px;
margin-right: 5px;
}

This is how my html looks:

<nav class="navbar navbar-light navbar-expand-xl fixed-top ">
    <a class="navbar-brand "> <img src="x" alt="logo" style="width: 310px"></a>
    <button class="navbar-toggler" data-target="#collapsingNavbarLg" data-toggle="collapse" type="button">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="navbar-collapse collapse" id="collapsingNavbarLg">
        <ul class="navbar-nav float-right text-right pr-3">
            <li class="nav-item">
                <a class="nav-link py-0" href="/" style="font-size: 130%;">Home</a>
            </li>
            <li class="nav-item">
                <a class="nav-link py-0" href="ChiSono" style="font-size:130%;">Chi Sono</a>
            </li>
            <li class="nav-item">
                <a class="nav-link py-0" href="Servizi" style="font-size:130%;">Servizi</a>
            </li>
            <li class="nav-item">
                <a class="nav-link py-0" href="Contattaci" style="font-size:130%;">Contattaci</a>
            </li>
            <li class="nav-item">
                <a class="nav-link py-0" href="AreaClienti" style="font-size:130%;"> Area Clienti</a>
            </li>
        </ul>
    </div>
</nav>

The constant 200px padding and the consistent spacing between li elements seem to be causing these problems. Is there any way to preserve the spacing for my navbar elements even as they resize? Or perhaps another solution to rectify this? Thanks!

My solution to the issue involved utilizing viewport units (vw) for setting the width of the image. By doing so, I ensured that the element's aspect ratio was maintained in accordance with the viewport width.

.navbar-brand img {
max-width: 13vw; /* adjust value as needed */
display: block;
width: 100%;

}

I reorganized everything within a container to eliminate the need for a 200px padding adjustment for your logo. This allows the navigation to maintain a similar appearance to what you had in your original code, without forcing the elements into specific positions.

This modification also enables you to align your navigation items to the right using a new CSS class I created called .navbar-right.

Due to the change in positioning, I included an additional media query to adjust the mobile hamburger menu. It may not be necessary in your coding environment since I developed this directly from my desktop with only CSS, excluding JS from the example.

I hope this explanation is beneficial to you.

.navbar-right {
  position: absolute;
  right: 0;
}

.relative {
  position: relative;
}

@media only screen and (max-width:768px) {
  .navbar-brand {
    max-width: 100px;
  }
  /* The following is intended for demonstration purposes and could help you position 
  the hamburger menu on mobile devices */
  .navbar-toggler {
    right: 0;
    position: absolute;
    margin: 10px;
  }
}

To optimize image display on different viewports, it is recommended to create separate image files for each size and use the srcset attribute to determine which image should be displayed based on the viewport size.

For example:

<img src="small.jpg" srcset="small.jpg 320w, medium.jpg 600w, large.jpg 900w" alt="my company">

You specify the image file name/location followed by the viewport size at which that particular image should be displayed. The width of the viewport at which the image should be shown is denoted by the w unit. In the above example:

The small.jpg is displayed until the viewport width reaches 320px
The medium.jpg is displayed until the viewport width reaches 600px
The large.jpg is displayed until the viewport width reaches 900px
