Bootstrap multi-column carousel smooth scrolling/easing - javascript

I'm trying to get the following multi-item carousel to scroll smoothly to the next item. Right now, it jumps to the next item when clicked, but I would like it to transition/ease - or go smoothly - to the next section.
<style>
body {
width: 1400px;
}
.Blog {
position: relative;
background-color: #000;
}
.inner {
overflow: hidden;
font-size: 0;
white-space: nowrap;
}
.Blog-item {
border-left: 1px solid #fff;
border-right: 1px solid #fff;
display: inline-block;
}
.controlDiv {
border-left: 1px solid #fff;
border-right: 1px solid #fff;
text-align: center;
}
.control {
color: #fff;
font-size: 20px;
display: inline-block;
padding: 4px;
}
</style>
<div class="Blog">
<div class="inner">
<div class="Blog-item" >
<img src="http://placehold.it/727x356?text=1" alt="" />
</div>
<div class="Blog-item">
<img src="http://placehold.it/727x356?text=2" alt="" />
</div>
<div class="Blog-item">
<img src="http://placehold.it/727x356?text=3" alt="" />
</div>
<div class="Blog-item">
<img src="http://placehold.it/727x356?text=4" alt="" />
</div>
<div class="Blog-item">
<img src="http://placehold.it/727x356?text=5" alt="" />
</div>
<div class="Blog-item">
<img src="http://placehold.it/727x356?text=6" alt="" />
</div>
</div>
<div class="controlDiv">
<a class="control control-left glyphicon glyphicon-menu-left" href=""></a>
<a class="control control-right glyphicon glyphicon-menu-right" href=""></a>
</div>
</div>
<script>
$(document).ready(function () {
$('.control-right').click(function () {
$(this).blur();
$(this).parents('.Blog').find('.Blog-item').first().insertAfter($(this).parents('.Blog').find('.Blog-item').last());
return false;
});
$('.control-left').click(function () {
$(this).blur();
$(this).parents('.Blog').find('.Blog-item').last().insertBefore($(this).parents('.Blog').find('.Blog-item').first());
return false;
});
});
</script>
Here's the fiddle: http://jsfiddle.net/bcw8dysawk/z1wo4uy6/3/

If I understand you correctly, I think you are after something like this:
http://jsfiddle.net/uh2skm0e/
I basically used jQuery's animate function to animate elements on the page and inserted a modified version of your original code into the animate's callback function.
I completed the 'next slide' operation by modifying the margin-leftcss attribute and the 'previous slide' operation by modifying the left css attribute.
You can see both options and pick your preferred method (left is generally used).
I also needed to add a position:relative to the .Blog-item css rule since the script manipulates z-index and this requires elements to have an explicit CSS position.
Two things to mention:
1) My solution is a pure JavaScript solution. You can look into using the transition CSS attribute to achieve animations without the need for JavaScript, but you may need to reorganise your code slightly (which leads me onto my next point)
2) Usually with sliders, the element positions are not actually changed in the markup...it's only the visibility settings (display CSS attribute) that are changed. So when 'slide 2' displays, all slides are set to display:none except for 'slide 2'. This means all you need to do is use JavaScript to add a class to the visible slide and it will display...couple this with the transition CSS attribute and you can easily achieve some good effects.
Let me know if this is what you were after.

How to position/align a button using CSS

I'm learning web design and I'm struggling to position a button. I'm a beginner and trying to recreate league of legends client which is pretty simple in browser just for exercise, but I don't know how to use javascript and I can not find the solution online.
So this is how I want it to look: https://prnt.sc/pos3gf
I've tried to add logo and button in list and then display: inline but that doesn't really work or I just don't know to make it work.
This is my code
https://codepen.io/simic21/pen/poowQXK
I removed all of the CSS before /*====== REGION ======*//* Dropdown Button */ and replaced it with this:
.logo {
display: inline-block;
}
.region {
display: inline-block;
}
That will display the logo and region divs side by side. Now the only thing left is to add the rest of your desired styling such as padding or margin.
Add to your .region class display:inline-block and the same to your .logo class:
.region {
padding: 20px;
display:inline-block;
}
.logo {
padding: 40px 0px 0px 50px;
display:inline-block;
}
<div class="centered">
<div class="logo">
<img src="assets/img/logo.png" alt="logo">
</div>
<div class="region">
<button onclick="myFunction()" class="dropbtn">
<strong>EUNE(EN)</strong></button>
</div>
</div>

Why my jQuery effect not performing like it state?

I have 3 questions about my jQuery study today.
Why my jQuery code not have the animation effect as it should be? for example, .slideUp() and .slideDown(), my code shows something strange instead of slideUp animation.
I understand, the .hide() or .slideUp() function is only to HIDE the div box, not DELETE them, however, in my code, why the position of other div boxes changed after a DIV .hide()? Shouldn't it stay at their original position as the DIV box is still there, just HIDED?
How can I achieve to let other DIVs stay at the original position, when one DIV box has been hided?
$(document).ready(function() {
$('#panel1').slideUp(1000).delay(1500).slideDown(1000);
});
.panel {
display: inline-block;
width: 80px;
height: 60px;
border: 1px solid green;
position: relative;
top: 20px;
margin-left: 45px;
border-radius: 5px;
}
.panelTop {
height: 30px;
background-color: blue;
color: white;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<div class="panels">
<div id="panel1" class="panel">
<div class="panelTop">#panel1</div>
<div class="panelBottom">content</div>
</div>
<div id="panel2" class="panel">
<div class="panelTop">#panel2</div>
<div class="panelBottom">content</div>
</div>
<div id="panel3" class="panel">
<div class="panelTop">#panel3</div>
<div class="panelBottom">content</div>
</div>
<div id="panel4" class="panel">
<div class="panelTop">#panel4</div>
<div class="panelBottom">content</div>
</div>
</div>
For your first question
Why my jQuery code not have the animation effect as it should be? for
example, .slideUp() and .slideDown(), my code shows something strange
instead of slideUp animation.
The .slideUp() method animates the height of the matched elements. Means it animates height so it reaches 0 (or, if set, to whatever the CSS min-height property is). See here for reference. That is exactly what is happening to your first box it is decreasing in height.
Afterwards the display style property is set to none to ensure that the element no longer affects the layout of the page.
What display none does ?
display:none means that the tag in question will not appear on the
page at all
Now for second and third question
I understand, the .hide() or .slideUp() function is only to HIDE the
div box, not DELETE them, however, in my code, why the position of
other div boxes changed after a DIV .hide()? Shouldn't it stay at
their original position as the DIV box is still there, just HIDED?
How can I achieve to let other DIVs stay at the original position,
when one DIV box has been hided?
The .hide() and .slideUp()function they both add display:none to your tag element. Means they are gone now
Now what can you do to let them stay there, But hidden from view ?
You can use visibility or opacity property instead rather than using display
property.
For example: visibility: hidden; will just hide it from the view.
Will update your fiddle in order to demonstrate it in a while. Hope this will help you. Please feel free to ask if not clear. Thank you.
$(document).ready(function() {
setInterval(function(){
$('#panel1').slideUp(1000).delay(500).slideDown(1000);
}, 3000);
});
.outer-div
{
position: relative;
display: inline-block;
min-height: 1px;
margin-right: 15px;
margin-left: 15px;
width: 130px;
height: 90px;
}
.panel {
border: 1px solid green;
margin-left: 45px;
border-radius: 5px;
position:absolute;
top:0;
width: 100%;
}
.panelTop {
height: 30px;
background-color: blue;
color: white;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<div class="panels">
<div class="outer-div">
<div id="panel1" class="panel">
<div class="panelTop">#panel1</div>
<div class="panelBottom">content</div>
</div>
</div>
<div class="outer-div">
<div id="panel2" class="panel">
<div class="panelTop">#panel2</div>
<div class="panelBottom">content</div>
</div>
</div>
<div class="outer-div">
<div id="panel3" class="panel">
<div class="panelTop">#panel3</div>
<div class="panelBottom">content</div>
</div>
</div>
<div class="outer-div">
<div id="panel4" class="panel">
<div class="panelTop">#panel4</div>
<div class="panelBottom">content</div>
</div>
</div>
</div>
You should use display:flex on .panels, that solves your first question.
For second question you should use visibility or opacity.
With current code you are removing it, although it is called hide() it is equivalent to CSS display:none; which doesn't keep space of element.
Although you actually don't need to set visibility in your case because sliding it up will hide element and down show.
Something like this:
$('#panel1').animate({
top: -62 // 60 is height of element plus 2px of borders
}, 1000).delay(1500).animate({
top: 0
}, 1000);
Also you have to change CSS a bit.
Add this to your CSS:
.panels {
display: flex;
overflow: hidden;
margin-top: 20px;
}
And from .panel remove top: 20px;

jQuery Mobile: Trying to get an icon to display in the middle of some text

I'm trying to get the icon to display in the middle of the words 'some text'.
Could anyone advise?
http://jsfiddle.net/LZxxB/50/
<div>
<div style="display:inline-block;">some</div>
<span class='ui-btn-icon-notext ui-icon-arrow-u-l' style="display:inline-block;"></span>
<div style="display:inline-block;">text</div>
</div>
Here is one way to do it. You basically make an icon button that is not a button.
The HTML:
<div>
<div style="display:inline-block;">some</div>
<span class="ui-nodisc-icon ui-alt-icon nonbuttonicon" >
<span class="ui-btn ui-icon-delete ui-btn-icon-notext ui-btn-inline"></span>
</span>
<div style="display:inline-block;">text</div>
</div>
The CSS:
.nonbuttonicon .ui-btn {
background: transparent;
cursor: default;
border: 0;
margin: 0;
}
.nonbuttonicon .ui-btn:hover{
background: inherit;
}
DEMO
UPDATE:
Here is a way without using jQM buttons and a single span:
<div>
<div style="display:inline-block;">some</div>
<span class="ui-alt-icon ui-icon-delete ui-btn-icon-notext inlineIcon"></span>
<div style="display:inline-block;">text</div>
</div>
.inlineIcon {
display: inline-block;
position: relative;
vertical-align: middle;
}
.inlineIcon:after{
background-color: transparent;
}
Updated DEMO
An if you like the white icon on top of the round disk, the CSS becomes even simpler:
<span class="ui-icon-delete ui-btn-icon-notext inlineIcon"></span>
.inlineIcon {
display: inline-block;
position: relative;
vertical-align: middle;
}
DEMO
These lines of code will reset the jquery mobile css that is displaying it differently. You might need to tweak it a little bit to fit your needs.
div span.ui-icon-arrow-u-l:after {position:relative;}
div span.ui-icon-arrow-u-l {display:inline-block;height:30px;margin-top:0;width:16px;}
Hope this helps.

Change multiple images/elements on hover for overlayed images HTML

I created a notecard image where i overlayed multiple images on top of it. These are elements of the notecard. I want it so that when I hover over the notecard, I can completely change the contents on the notecard image (overlaying new things onto the notecard).
So right now, I have this right now:
<div style="position:relative;">
<a href="#games">
<img id "image_a" a" src="images/card_normal.png" onmouseover "this.src rc 'images/hover/card_hover.png';" ;" onmouseout "this.src rc 'images/card_normal.png';" ;" style="position: absolute; top: 0; left: 0;"/>
<img id "image_b" b" src="images/category_icons/icon_games.png" style="position: absolute; top: 10px; left: 40px;"/>
<img id "image_c" c" src="images/category_titles/title_games.png" style="position: absolute; top: 160px; left: 40px;"/>
</a>
</div>
Where the notecard changes into a "hovered" version, but I am unable to change anything else. I want it so that whenever the mouse pointer is in the notecard (including if its on other elements inside the notecard), the contents change. I want to completely scrap the contents of it (so the title and icon) and change it so I can add text and overlay new images.
How can I do this in JS/HTML/etc?
If the two versions (hover/non-hover) are significantly different (and you want a no-js solution), you could have two divs, one set to hide, one set to show. Then on-hover, you change their visibility. Fiddle.
<div class="card">
<div class="no-hover">
stuff you want to show when the user is just looking
</div>
<div class="on-hover">
stuff you want to show when the user hovers
</div>
</div>
CSS:
.no-hover {
display: block;
}
.on-hover {
display: none;
}
.card:hover > .on-hover {
display: block;
}
.card:hover > .no-hover {
display: none;
}
It's extra HTML elements, but might be easier to maintain.
Based on your comment to Learner's answer, here is an example of the idea you are describing:
HTML:
<div class="outer">
<div class="inner"></div>
<div class="inner"></div>
<div class="inner"></div>
<div class="inner"></div>
</div>
CSS:
.outer {
width: 304px;
height: 304px;
background-color: black;
}
.inner {
float: left;
width: 150px;
height: 150px;
background-color: red;
border: 1px solid black;
display: none;
}
.outer:hover .inner {
display: block;
}

How to align center two pictures in Jquery Mobile

How to align two pictures so that they are center of the div when using JqueryMobile and as far from the both sides? --p--p--
<div class="ui-grid-a" style="margin: 10px;"">
<div class="ui-block-a" id="pic" align="center">
<img src="images/image1_100x100.jpg" data-theme="c" id="pictureId"/>
</div>
<div class="ui-block-b">
<label>&nbsp</label>
</div>
<div class="ui-block-c" id="pic" align="center">
<img src="images/image2_100x100.jpg" data-theme="c" id="pictureId2"/>
</div>
</div>
<style>
div#pic { color:red; border:4px solid grey; border-radius: 15px; width:130px; height:130px
text-align:center; background-color: white; margin: 0 auto;}
</style>
Second question is that what is the correct way to make a gap between divs? I am using now empty div, but I think that there might be something better?
Cheers,
Sami
You can always add css to that and overwrite the JQM stuff when you insert your css after the JQM css links.
I took your code and modified it a little bit so it should give you a starting pont. I don't know if any of your or JQM css interferes with that as I can't try out right now.
The CSS in my case is in no way smaller because of all the compatibility css (prefixed properties). But the advantage is that box layout is a lot more flexible in that it also allows to center the content in 2 directions and also allows for sorting and alignment.

This is just an alternative.

I got it working. I guess it is not so sophisticated solution, but it is working.
.pics {
background-color: white;
border-radius: 15px;
border: 4px solid grey;
height: 130px;
padding: 0px;
text-align: center;
width: 130px !important;
}
.picLeft {
float:left;
margin-left: 10px !important;
}
.picRight {
float:right;
margin-right: 10px !important;
}
I am open to any better solutions and thanks Torsten!
