Custom Slider Shortcode Area For Home Page

Hi I use the following code to display header video background autoplay. But this video is not playing automatically in browsers as well as on mobile screens. <video class="evideo" src="https://ipassexam.ca/wp-content/uploads/2020/06/ipass_5.mp4" autoplay="1" loop=""></video> Moreover, it is not responsive / not fitting into mobile screens. Thanks & regards Ratnakar N
