I want to reduce the size of my image for mobile view - bootstrap

I have a section with 2 columns, 1 for image and 1 for text.

The code for this is

<div class="row aboutRow">
       <div class="col-lg-3 col-sm-2 col-xs-3 col-md-3 text-center">
        <img src="assets/img/logoWithTagline.png" class=" img-fluid logoAbout" alt="">
      </div> 
      <div class="col-lg-9 col-sm-10 col-xs-9 col-md-9 pt-4 pt-lg-0 content d-flex flex-column justify-content-center" data-aos="fade-up" data-aos-delay="100"> 
          <div>

in the mobile view I want to reduce the size of the image, because there is a carousel above it and the image looks super huge and not looking good.

I want to reduce the size of this image to around 40% only for mobile view.

I tried to change the max-width of 100% in img-fluid but then the desktop view is getting altered. I want width to be 100% for desktop view and 40% for mobile view.

You can use media queries for this. You define a width that is baed on media query as follows for example as below:

@media (max-width: 767px) {
  .img-mob {
    width: 40%;
  }
}

Then, you can use your css class with the img element:

<img src="assets/img/logoWithTagline.png" class="img-fluid logoAbout img-mob" alt="">
