How do I remove accordion animation?

Site URL: https://dylansoffice.com/team

When someone clicks Information on the site, a markdown/dropdown accordion animation occurs to reveal more text. How do I eliminate the accordion animation? I'd just like the text to appear or pop-up immediately after clicking Information. 

I currently have this code pasted into the page header code injection:

<script>
$(document).ready(function(){
$('.markdown-block .sqs-block-content h4').addClass('ui-closed').css('cursor','pointer');
$(".markdown-block .sqs-block-content h4").nextUntil("h4").slideToggle();
$(".markdown-block .sqs-block-content h4").click(function() {

$(this).nextUntil("h4").slideToggle();
$(this).toggleClass('ui-closed ui-open');
});
});
</script>

Hi. You can use Accordion Block, instead of using code to add accordion

Okay, that works. Can I remove the "+" or "v" icon and have an underlined header instead?

Add this to Design > Custom CSS

/* hide accordion plus arrow */
.accordion-block .plus {
    opacity: 0;
}
/* underline accordion title */
span.accordion-item__title {
    border-bottom: 1px solid black;
    display: inline-block;
}

Does this target all accordion blocks site-wide? Is it possible to only target a specific page?

Edit page > Add a Code Block at bottom of page > Paste this code

<style>
  /* hide accordion plus arrow */
.accordion-block .plus {
    opacity: 0;
}
/* underline accordion title */
span.accordion-item__title {
    border-bottom: 1px solid black;
    display: inline-block;
}
</style>
