Is there a way to make navbar logo responsive? - html

Question

So, here is the website I've built using bootstrap 4.
I have a big issue with the logo, as it keeps the same size on all devices.
I've tried adding img-fluid, but if I add this class, the logo shrinks so much on mobile phones, that it looks like a tiny dot. So I've removed this class. Now, on mobile, the hamburger moved on the second line and on the first line of the navbar is the 310 px logo that doesn't even show completly. I want to keep this spacing between the navbar elements as it now, but I think the problem that may be actually comes 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 my html:
<nav class="navbar navbar-light navbar-expand-xl fixed-top ">
<!-- Brand/logo -->
<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">
<!-- Links -->
<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>
That 200px from padding also keeps the same, and maybe this is why I get all this issue. I am not sure. Also the space between the li elements, as I shrink the page until the point it becomes hamburger. But is there a way to still keep this spacing for my navbar elements, that also resizes? Or is there another way to fix this? Thank you!

Answer 1

I moved everything into a container so that you do not have to use 200px padding to move your logo. This lets the navigation sit similarly to the dimensions/look you had in your code without forcing the position of the elements.
This will let allow you to position your nav items to the right using a css class I added called .navbar-right.
But, because of the new positioning I added another media query to move the hamburger menu. (You may not need this in your coding environment because I was working straight off my desktop with just the CSS, also JS is not added to the example.)
Hope this helps.
.navbar-right {
position: absolute;
right: 0;
}
.relative {
position: relative;
}
#media only screen and (max-width:768px) {
.navbar-brand {
max-width: 100px;
}
/* below is for the demo but might help you position
the hamburger menu on mobile */
.navbar-toggler {
right: 0;
position: absolute;
margin: 10px;
}
}

Answer 2

The best option would be to create diffenrent images files for different view port sizes.
With the srcset attribute, you can select which image should show in which case.
Here an example:
<img src="small.jpg" srcset="small.jpg 320w, medium.jpg 600w, large.jpg 900w" alt="my company">
You give the name/location of the image file, followed by a space and the view port size, when the image should show. It describes until which width (that's why it's w) the image should show. The example above translates to:
the small.jpg is shown until a view port width of 320px
the medium.jpg is shown until a view port width of 600px
the large.jpg is shown until a view port width of 900px

Answer 3

I solved this problem using an vw units width of image.
This allows the element's aspect ratio to be preserved, based on the viewport width
.navbar-brand img {
max-width: 11vw; /* find suitable value for you */
display: block;
width: 100%;
}
