so my problem is that i have 3 images with uneven width and still make them intact until it hit a certain width let's say 767px. and when it hit that width each of the images will take a full width of 767px until xs size of screen. sorry if this sentence construction make you crazy.
here's a piece
<div class= "about-content">
                    <ul>
                        <li><a href="">
                            <div class = "inner-content">
                                <img src="img/about/1.jpg" class="img-fluid">
                            </div>
                                </a></li><li><a href="">
                                <div class = "inner-content">
                                    <img src="img/about/2.jpg" class="img-fluid">
                                        <div class = "overlay-content">
                                            <h4>Book a Test Drive <i class = "fa fa-chevron-circle-right"></i></h4>                                 
                                        </div>
                                </div>
                                </a></li><li><a href=""><img src="img/about/3.jpg" class="img-fluid"></a></li>
                    </ul>
                    <ul>
                                <li><a href=""><img src="img/about/4.jpg">
                                </a></li><li><a href=""><img src="img/about/5.jpg">
                                </a></li><li><a href=""><img src="img/about/6.jpg"></a></li>
                    </ul>
                </div>
				
                        
The images will expand if you use
vw(viewport width) measurement. Set a calculation to compensate for their starting positioning as inwidth: calc(100vw - 70px)Here's a snippet:
