@dhavalveera - yes, but bootstrap has a class that sets that property. If you're intent on using Bootstrap, at least in v4, that's what they provide. You can always add custom CSS if you want to. If not, then you can use the classes that they defined. Both should work.

but if we use Bootstrap 4 then we can't the style of that tag

either custom css or in Bootstrap

it is not changing quickly

@SweetCodingInc

@eabg it should be $('.btn').on('click'....

you're missing . before btn

Ehidin

@eabg

oh man really? let me check it out

Sweet Coding :)

@SweetCodingInc

and also, in your html, there is no element that has class="btn"

so it's not going to work either way

Do you want to attach event handlers to all your buttons?

From the html you've shared, you need to do

$('button').on('click'....

Ehidin

@eabg

I orginally had button with no luck

so I tried that out and nothing

Sweet Coding :)

@SweetCodingInc

what do you want to happen when you click the button?

The event handler doesn't look right to me

Ehidin

@eabg

so im just trying to add some css changes to boxes..later do animate

Sweet Coding :)

@SweetCodingInc

With your code, let's say you click on the button 1. Then the clickButtonId will be btn1

and your selector will be#box1btn1

and there is no element with id="box1btn1"

Ehidin

@eabg

let me show you this. this was an earlier test and it was working before:

I wanted to start over cause an element got lost and i couldnt get it working again

Sweet Coding :)

@SweetCodingInc

@eabg you're better off using data attribute to target specific box

I'll show you an example

Ann Kaniga

@annkaniga

@eabg did u try any debug?

Ehidin

@eabg

@lolativiwe_twitter

function diffArray(arr1, arr2) {
    var newArr = arr1.concat(arr2);
    newArr.filter(function(index) {
        if (!arr1.includes(index) || !arr2.includes(index)) {
            return newArr;
        }
    });
    console.log(newArr);
}

diffArray([1, 2, 3, 5], [1, 2, 3, 4, 5]);

can someone tell me whats wrong with this?

it always returns the concatenated array of the two

Aditya

@ezioda004

@lolativiwe_twitter .filter() returns a new array and doesnt mutate the original one so you're returning the concatenated array from the 2nd line
