#762

Short Description and Why It's Useful

• The main element's top margin is removed, its height is set to 100%, and vertical overflow is hidden. Because of this, the main element now takes up the full height of the page.
• The section and aside elements are allowed to scroll independently, their scrollbars are hidden, and padding is added to their top.
• Since scrolling is now moved to the section, a scroll event and the enableScrolling function have been added to it. These help toggle the isScrollingEnabled flag to control whether infinite scrolling can be triggered.
• Additionally, the class ion-content-scroll-host has been added to the section to let ion-infinite-scroll recognize the scrolling element.
• Also updated the space variable for the job cards' margin-block.
