CSS conflicts when adding two different custom modules

Hi everyone,

We are using Trust theme by Impact. We recently created two custom modules in one page. The problem we are trying to solve is that when we add custom module 1 it works fine but then when we add custom module 2 it looks like it affects the css of custom module 1 so it breaks. How can we avoid that? I am adding the code for both modules below. Thanks in advance.
Custom Module 1 HTML:
<section class=“HSS” onload=“addAnimationClass()”>
<div class=“container”>
<div class=“bg”>
<img class=“id-1” src=“https://3454737.fs1.hubspotusercontent-na1.net/hubfs/3454737/Home%20Page%20Assets/hero%20section%20experimetn_5.jpg” alt=“”>
<img class=“id-2” src=“https://3454737.fs1.hubspotusercontent-na1.net/hubfs/3454737/Home%20Page%20Assets/data_science_img_hero_section_home_page.jpg” alt=“”>
<img class=“id-3” src=“https://3454737.fs1.hubspotusercontent-na1.net/hubfs/3454737/Home%20Page%20Assets/hero%20section%20experimetn_6.jpg” alt=“”>
