How can I style an element which shares the same class

I have a page which shares the same class, I want one page (top.cfm) to have a border with a background-color but I don't want the (landing page.cfm) to have the border or background-color. This is my code on jQuery. Where am I going wrong?
$(function(){
if (window.location.pathname == "common/top.cfm") {
$('.content-padding').show('.content-padding').css('background-color', '#fff', 'border', '1px solid #CCCCCC');
} else (window.location.pathname == "common/landing_page.cfm")
{
$('.content-padding').css('background-color', '#E1E1E0', 'border', 'none')
}
});

It looks like you're using an else but with a conditional. try to use an else if instead.
And you can make two separate classes and use a toggle class on them, if you want.
Code
$(document).ready(function () {
if (window.location.pathname == "common/top.cfm") {
$('#content').toggleClass('content-padding-top');
}else if(window.location.pathname == "common/landing_page.cfm"){
$('#content').toggleClass('content-padding-landing-page');
}
});
.content-padding-top{
background-color:#fff;
border:1px solid #CCCCCC;
}
.content-padding-landing-page{
background-color:#E1E1E0;
border:none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="container main-content content-padding content-bordered container_12 clearfix" id="content">
<div class="grid_12 clearfix">
<div class="clearfix" >
<h1>Page Content</h1>
</div>

jQuery - progressivly showing div

I would like to show some divs, one by one, with a sliding effect from the left or right part of the screen. So far i'm stuck between this
<button id='animer'>animer</button>
<div class="left">from left</div>
<div class="right">from right</div>
<div class="left">from left</div>
<div class="right">from right</div>
<script>
$(function() {
$('.left, .right').hide();
$('#animer').click(function() {
$(".left").toggle("slide", {direction: "left"}, 500);
$(".right").toggle("slide", {direction: "right"}, 500);
});
});
</script>
and that
<button id='animer'>animer</button>
<div class="all">from left</div>
<div class="all">from right</div>
<div class="all">from left</div>
<div class="all">from right</div>
<script>
$(function() {
$('.all').hide();
$('#animer').click(function() {
$('.all').first().show('slow', function showNextOne() {
$(this).next('.all').show('slow', showNextOne);
});
});
});
</script>
But i need this to work no matter the divs order, because the "left" or "right" items will come randomly.
Help will be much appreciated as i am not as competent as i wished in jQuery. ^^

The following uses the all variable to keep a list of all of the divs. When the button is clicked, the slideNext() function is executed, checking the class of the current item to decide on toggle direction, and specifying slideNext (itself) as the function to run when the toggle is complete.
$(function() {
var all = $('.left, .right').hide();
$('#animer').click(function() {
var i = 0;
(function slideNext() {
if (i < all.length) {
var current = all.eq(i);
current.toggle("slide", {
direction: current.hasClass("left") ? "left" : "right"
}, 500, slideNext);
}
i++;
})();
});
});

<script src="https://code.jquery.com/ui/1.9.2/jquery-ui.min.js"></script>
<button id='animer'>animer</button>
<div class="left">from left</div>
<div class="right">from right</div>
<div class="left">from left</div>
<div class="right">from right</div>

You can use index from each() loop for delay and set direction based on condition if current div hasClass() left or not.
$(function() {
$('div').hide();
$('#animer').click(function() {
$('div').each(function(i) {
let dir = $(this).hasClass('left') ? 'left' : 'right';
$(this).delay(i * 1000).toggle('slide', {direction: dir})
})
});
});

Adding and removing classes depending on other elements

So I have carousel with slides (works on fullPage.js):
<div id="myContainer">
<div class="section" data-anchor="skynet">
<div class="slide one" data-anchor="main">
Slide 1
</div>
<div class="slide two" data-anchor="about_us">
Slide 2
</div>
<div class="slide three" data-anchor="faq">
Slide 3
</div>
<div class="slide four" data-anchor="news">
Slide 4
</div>
</div>
</div>
And I have some blocks with backgrounds
<div class="bg-main" id="bgOne"></div>
<div class="bg-main" id="bgTwo"></div>
<div class="bg-main" id="bgThree"></div>
<div class="bg-main" id="bgFour"></div>
Slides swaps by adding class active to blocks with class .one, .two etc.
I try to add class to blocks with background depend on active slide. For example - if .slide.two has class .active, add class to block #bgTwo.
Here my current JS. It doesn't work:
<script type="text/javascript">
$(document).ready(function(){
if ( $('#myContainer .one').hasClass('active') ) {
$('.bg-main').removeClass('active');
$('#bgOne').addClass('active');
} else if ( $('#myContainer .two').hasClass('active') )
{
$('.bg-main').removeClass('active');
$('#bgTwo').addClass('active');
}
});
</script>

Use the callback onSlideLeave
Demo
$(document).ready(function() {
$('#fullPage').fullpage({
onSlideLeave: function(link, secIdx, sldIdx, dir, next) {
$('.test .bg-main').removeClass('active');
$('.test .bg-main').eq(next).addClass('active');
}
});
});
.slide {
text-align: center
}
.test {
position: fixed;
top: 75%;
right:calc(50% - 220px);
}
.bg-main {
height: 30px;
width: 100px;
background: grey;
display:inline-block;
text-align:center;
outline:1px solid #fff;
margin:0;
}
.one,
#bgOne.active {
background: #fc0;
}
.two,
#bgTwo.active {
background: #f00;
}
.three,
#bgThree.active {
background: #0f0;
}
.four,
#bgFour.active {
background: #00f;
}
<link href='https://cdn.jsdelivr.net/jquery.fullpage/2.9.4/jquery.fullpage.min.css' rel='stylesheet'>
<div id="fullPage">
<div class="section" data-anchor="skynet">
<div class="slide one" data-anchor="main">
Slide 1
</div>
<div class="slide two" data-anchor="about_us">
Slide 2
</div>
<div class="slide three" data-anchor="faq">
Slide 3
</div>
<div class="slide four" data-anchor="news">
Slide 4
</div>
</div>
</div>
<div class='test'>
<div class="bg-main active" id="bgOne">1</div>
<div class="bg-main" id="bgTwo">2</div>
<div class="bg-main" id="bgThree">3</div>
<div class="bg-main" id="bgFour">4</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src='https://cdn.jsdelivr.net/jquery.fullpage/2.9.4/jquery.fullpage.min.js'></script>

So i found out that fullpage.js use event afterSlideLoad. So thats my solution:
<script type="text/javascript">
$(document).ready(function() {
$('#myContainer').fullpage({
anchors: ['skynet'],
menu: '#menu',
scrollingSpeed: 500,
normalScrollElements: '.modal',
scrollOverflow: true,
afterSlideLoad: function( anchorLink, index, slideAnchor, slideIndex){
var loadedSlide = $(this);
if(slideIndex == 0){
$('.bg-main').removeClass('active');
$('#bgOne').addClass('active');}
if(slideIndex == 1){
$('.bg-main').removeClass('active');
$('#bgTwo').addClass('active');}
if(slideIndex == 2){
$('.bg-main').removeClass('active');
$('#bgThree').addClass('active');}
if(slideIndex == 3){
$('.bg-main').removeClass('active');
$('#bgFour').addClass('active');}
}
})
});
</script>
Class is added only after the slide is changed, and not during the process itself. The background does not change as fast as I'd like, but this is the best thing I could achieve.

The perfect solution is to extend the fullpage.js to handle the feature.
This is a workaround:
<script type="text/javascript">
var updateClasses = function(){
var activeClass = 'active';
var eq = $('#myContainer').children(activeClass).eq();
var bgMain = $('.bg-main').removeClass(activeClass);
bgMain.eq(eq).addClass(activeClass);
};
$(document).ready(function(){
$(".fp-controlArrow").on("click.updateClasses", function(){
updateClasses();
});
});
</script>

how to check if it was the last element

how can I check if it was the last div? If it was I need to remove all classes "ready"
html:
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>
js:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var x = $("div:first").addClass("ready");
var c = $("div");
$(".ready").css("display", "block");
if (c.hasClass("ready")) {
$(".ready:last").next().addClass("ready");
}
}
})
;

Looking at your code what I understand is you want display one div after each second. For that I'll suggest following approach.
First add hidden class to all divs and then remove it from first hidden div at each second.
$(function() {
$('div').addClass('hidden');
var i = setInterval(showBlock, 1000);
function showBlock() {
var x = $("div.hidden:first").removeClass("hidden");
if($("div.hidden").length == 0) {
clearInterval(i);
}
}
});
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="green">Green</div>
<div class="orange">Orange</div>
<div class="red">Red</div>
<div class="green">Green</div>
<div class="orange">Orange</div>

As far as I understand your problem, following solution must work in your case:
$(function() {
setInterval(showBlock, 1000);
function showBlock() {
var ready_divs = $("div.ready").length;
var total_divs = $("div").length;
if(ready_divs!=total_divs){
if(ready_divs==0){
$("div:first").addClass('ready');
}else{
$("div.ready:last").next('div').addClass('ready');
}
}else{
$("div").removeClass('ready')
}
}
});
div{
width: 20px;
height: 20px;
border:1px solid red;
}
div.ready{
border:3px solid blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="green"></div>
<div class="orange"></div>
<div class="red"></div>
<div class="green"></div>
<div class="orange"></div>

detect click, check attribute value and text inside, and display element

I need to detect click of an element(.menuitem), check the text it contains.
And then based on the attribute(is-checked), hide or show other elements.
I need this only when clicking that other button.
<div class="items">
<div class="menuitem" is-checked="true">
<div class="ytp-menuitem-label">Button 1</div></div>
<div class="menuitem" is-checked="false">
<div class="ytp-menuitem-label">Button 2</div></div>
</div>
<div class="element">some content</div>
<div class="element">some more content</div>
$('.menuitem').click(function () {
if ($('.menuitem').text().trim() === "Button 2"){
if ($('[is-checked="true"]'))
$('.element').css('display', 'block');
if ($('[is-checked="false"]'))
$('.element').css('display', 'none'); }
});
Here's a JSFIDDLE, of what I have:

$('.menuitem').click(function() {
console.log($(this).text().trim())
if ($(this).text().trim() === "Button 2") {
if ($(this).attr('is-checked') == 'true') {
$('.element').css('display', 'block');
} else {
$('.element').css('display', 'none');
}
}
});
.items {
height: 30px;
margin-bottom: 5px;
}
.menuitem {
float: left;
margin-right: 10px;
border: 1px solid;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="items">
<div class="menuitem" is-checked="true">
<div class="ytp-menuitem-label">Button 1</div>
</div>
<div class="menuitem" is-checked="false">
<div class="ytp-menuitem-label">Button 2</div>
</div>
</div>
<div class="element">some content</div>
<div class="element">some more content</div>
<div class="element">even more content</div>
Use $(this).attr('is-checked') to get the value
Also use $(this).text().trim() to get the text of clicked element

You've got it a tad wrong, your if statement isn't actually looking at the element which was clicked. Try something along these lines:
$('.menuitem').click(function () {
// $(this) is a reference to the element which was clicked
if ($(this).attr('is-checked') == "true")
$('.element').css('display', 'block');
if ($(this).attr('is-checked') == "false")
$('.element').css('display', 'none');
});
