Javascript css display none display block transition

CSS can't make a transition from display: none to display: block for that i'm trying to make it using javascript i don't want to use visibility: hidden and height: 0 or transform: scale(0)

for that i'm using javascript to make a transition from display: none to display: block

The code below work when i add the active class the transition working fine, But when i remove the class active the transition it's not working

How can i make the transition work in both when i add and when i remove the class active using javascript and css ?

let parents = document.querySelectorAll('.parent');

parents.forEach(p => {
    p.addEventListener("click",() => {
        if(p.classList.contains('active')){
            setTimeout(function () {
                p.nextElementSibling.classList.remove("visually");
                
              }, 20);
                p.classList.remove("active");
           
        }else{
            p.classList.add("active");
            setTimeout(function () {
                p.nextElementSibling.classList.add('visually');
              }, 20);
        }

    });
});
.link-inner {
cursor: pointer;
}

.toggle {
    opacity: 0;
    display: none;
    transition: all .5s ease-in-out;
}

.parent.active+.toggle {
    display: block;
}

.parent.active+.visually {
    opacity: 1;
}
    <div class="link">
    <div class="link-inner parent">
        <div class="linkText">
            <h4>Title</h4>
        </div>
    </div>
    <div class="linkInfo toggle ">
    <a href="#" target="_blank">link 1</a>
    </div>
</div>

    <div class="link">
    <div class="link-inner parent">
        <div class="linkText">
            <h4>Title</h4>
        </div>
    </div>
    <div class="linkInfo toggle ">
    <a href="#" target="_blank">link 2</a>
    </div>
</div>

You were actually really nearly there. You just had to swap the calls when removing classes and add a bit more of a delay in your setTimeout

let parents = document.querySelectorAll('.parent');

parents.forEach(p => {
    p.addEventListener("click",() => {
        if(p.classList.contains('active')){
            // remove the class that sets opacity so it fades away
            p.nextElementSibling.classList.remove("visually");
            setTimeout(function () {
                // remove the class that sets display: block after the opacity is gone
                p.classList.remove("active");
                
              }, 500);
        } else {
            p.classList.add("active");
            setTimeout(
                function () {
                    p.nextElementSibling.classList.add('visually');
                },
                20
            );
        }

    });
});
