Switch up the CSS without resorting to toggleClass

When I hover over a div, I want to change some CSS properties. However, using 'toggleclass' didn't work as expected because the new background color wasn't overriding the existing class. So, I came up with the following method instead.

The challenge now is how to revert the CSS changes after hovering.

$('#menu_first_home').hover(function(){
$(this).css({ 'border': '10px solid rgba(186, 0, 0, 0.2)' });
$('.search-box').css({ 'background-color': 'rgba(186, 0, 0, 0.5)', 'color': 'rgba(186, 0, 0, 0.5)'    });
});

To achieve the desired effect, you can utilize the hover function in jQuery to dynamically change CSS attributes on mouseleave.

$('#menu_first_home').hover(
    function () { // Mouseenter
        $(this).css({
            'border': '10px solid rgba(186, 0, 0, 0.2)'
        });
        $('.search-box').css({
            'background-color': 'rgba(186, 0, 0, 0.5)',
            'color': 'rgba(186, 0, 0, 0.5)'
        });
    }, 
    function(){ // Mouseleave
        $(this).css({
            'border': '10px solid rgba(186, 0, 0, 0.2)'
        });
        $('.search-box').css({
            'background-color': 'rgba(186, 0, 0, 0.5)',
            'color': 'rgba(186, 0, 0, 0.5)'
        });
    }
);

Answer №2

To create dynamic hover effects using CSS, you can define classes for border styles and background colors. Toggle these classes on mouse over and out to style elements accordingly:

CSS - 

.customBorder{border: 2px dashed rgba(54, 103, 255, 0.7);}

.customBackground{background-color: rgba(255, 205, 97, 0.8);
                  color: rgb(90, 50, 20);}

jQuery -

$('#my_element').hover(function(){
   //for hover on
   $(this).addClass("customBorder");
   $('.description').addClass("customBackground");
},function(){
   //for hover off
   $(this).removeClass("customBorder");
   $('.description').removeClass("customBackground");
});

To address this issue, you can utilize the jQuery hover method in conjunction with CSS classes. The hover method is capable of accepting two callback functions: one for when the mouse pointer hovers over an item, and another for when it leaves:

$(item).hover(function() { ... }, function() { ... });

Instead of dynamically applying styles, it's recommended to define them within your CSS files:

#menu_first_home.hoverClass {
    border-color: rgba(186, 0, 0, 0.2);
}

Upon hovering, simply add a specific class (e.g. "hoverClass") to the designated element, and remove it upon mouse out.
