Tips for successfully changing the styling using CSS that was previously altered with JavaScript

I have already gone through this question but couldn't find a solution.
I used JavaScript to apply the style to the element with the id "left-container" instead of using a class, and now I'm unable to override it!

You can view the demo for a minimal reproducible example.

hideLeftContainer():void{
        console.log('hide')
        let element = document.getElementById('left-container')
        element.style.display = 'none'
}

This is the style that I want to apply without using a media query:

#left-container{
    display: block;
    position: static;
    max-width: 150px;
    min-width: 150px;
    flex-basis: 150px;
    background-color: white;
}

I've also attempted to override the style using the class selector but haven't had any success.
How can I resolve this issue? Thank you!

HTML

<button class="icon-button" (click)="showLeftContainer()">
    <fa-icon class="menu-icon" [icon]="faBars"></fa-icon>
</button>
...
Code truncated for brevity
...
</div>

Answer №1

There have been responses from some individuals, but your current layout necessitates the use of !important:

display: block !important;

Relying heavily on !important is not a recommended practice as it can result in CSS that is difficult to maintain. I suggest utilizing Javascript with class toggling instead. Here is an example:

    hideLeftContent():void {
        let targetElement = document.getElementById('left-content');
        targetElement.classList.add('hidden');
    }

To complement this, you will need to incorporate a specific CSS directive:

#left-content.hidden {
   display: none;
}
