Align text in the center by ignoring the absolutely positioned element

I am developing a flex table from scratch and the table supports filtering and sorting. The icons for filters and sorting are displayed in the table header (right corner). Also my table supports that the user can position the header text left/center;
My problem:
Since the icons are inside the table header, icons as well occupies some space. So when i position the elements in the center, i see the alignment gets disturbed as shown below.
body {
width: 100%;
}
.table-header, .table-body {
display: flex;
width: fit-content;
border: 1px solid black;
padding: 10px;
}
.header, .data {
display: flex;
min-width: 150px;
width: 150px;
border-right: 1px solid black;
display: flex;
justify-content: center;
position: relative;
}
.header .text {
width: 100%;
white-space: nowrap;
text-align: center;
overflow: hidden;
text-overflow: ellipsis;
}
.icons {
float: right;
right: 0;
display: flex;
}
<div class="table">

What i tried
So since the icons as well take some space, to avoid this i positioned them absolutely relative to the header. So the alignment problem got solved . But for long headers where ellipsis has to be shown, the ellipsis hides behind the icons as shown below
Code: Here
So what is the solution to this ? I want to maintain the center position by reducing the space occupied by the icons. Is it possible through CSS? Please help. Thanks :)

If you try to do that with absolute positioning you need to know what exact width your icons can take.
Then possible solution is to add padding rule (left/right) into table headers, so CSS code should be like this:
body {
width: 100%;
}
.table-header, .table-body {
display: flex;
width: fit-content;
border: 1px solid black;
padding: 10px;
}
.header, .data {
box-sizing: border-box;
padding: 0 30px;
display: flex;
min-width: 150px;
width: 150px;
border-right: 1px solid black;
display: flex;
justify-content: center;
position: relative;
}
.header .text {
width: 100%;
white-space: nowrap;
text-align: center;
overflow: hidden;
text-overflow: ellipsis;
}
.icons {
position: absolute;
right: 0;
}

How to use scrollWidth value of parent element using css?

I want to set width and height for cover element same as scrollWidth and scrollHeight of container element. So during the scrolling it will fully cover container. At the moment it uses width and height of container element cropped by scroll.
The whole area should be covered by green color. Is it possible to do using only css?
.container {
width: 400px;
height: 500px;
border: solid 2px;
position: relative;
overflow: auto;
}
.row {
width: 500px;
height: 60px;
border: solid 4px blue;
margin: 10px;
}
.cover {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: green;
opacity: 0.5;
}
<div class="container">
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="cover"></div>
</div>

I don't know your the final goal is, but have you tried simply applying the background to the container?
.container {
width: 400px;
height: 500px;
border: solid 2px;
overflow: auto;
background-color: rgba(0,128,0,.5);
}
.row {
width: 500px;
height: 60px;
border: solid 4px blue;
margin: 10px;
}
<div class="container">
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
</div>

You can use JavaScript to get the scrollWidth and scrollHeight of the parent.
const container = document.querySelector('.container');
const cover = document.querySelector('.cover');
cover.style.height = container.scrollHeight + "px";
cover.style.width = container.scrollWidth + "px";
.container {
width: 400px;
height: 500px;
border: solid 2px;
position: relative;
overflow: auto;
}
.row {
width: 500px;
height: 60px;
border: solid 4px blue;
margin: 10px;
}
.cover {
position: absolute;
top: 0;
left: 0;
background-color: green;
opacity: 0.5;
}
<div class="container">
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="cover"></div>
</div>

Here's a Javascript code to do it.
Quick reminder: document.querySelector(".cover") here return just the first element met but if there are more use document.querySelectorAll()
EDIT : You can do it with only CSS too by wrapping the rows in the cover (It's why i put Javascript in comments)
/*const { scrollWidth, scrollHeight } = document.querySelector(".container");
const coverElement = document.querySelector(".cover");
coverElement.style.width = `${scrollWidth}px`;
coverElement.style.height = `${scrollHeight}px`; */
.container {
width: 400px;
height: 500px;
border: solid 2px;
position: relative;
overflow: auto;
}
.row {
width: 500px;
height: 60px;
border: solid 4px blue;
margin: 10px;
}
.cover {
position: absolute;
top: 0;
left: 0;
background-color: green;
opacity: 0.5;
}
<div class="container">
<div class="cover">
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
</div>
</div>

try this
.container {
width: 400px;
height: 500px;
border: solid 2px;
position: relative;
overflow: auto;
}
.cover {
display: flex;
flex-direction: column;
width: 100vw;
height: 100vh;
background-color: green;
opacity: 0.5;
}
.row {
width: 500px;
height: 60px;
border: solid 4px blue;
margin: 10px;
}
<div class="container cover">
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>
<div class="row"></div>

Making a container appear with a button after making it disappear

I click on a div container (it disappears) and another one appears with a button. Then, I want to go back to the previous div container using a button made-up of a div container (keep in mind that I only want to perform this action in the currentTarget).
I only want to do this to the current container or the one clicked on!
$(document).ready(() => {
$('.shown').on('click', event => {
$(event.currentTarget).next('.tab').show();
$(event.currentTarget).hide();
});
$('.button').on('click', event => {
/*i want to hide the container with class tab and show the container with class shown*/
});
});
.shown {
width: 400px;
height: 100px;
background-color: green;
}
.con {
width: auto;
height: auto;
border: 1px solid black;
}
.main {
width: auto;
height: 170px;
background-color: red;
margin-top: 10px;
padding: 5px 10px;
}
.tab {
width: 400px;
height: 100px;
background-color: blue;
display: none;
}
p {
display: inline-block;
}
.button {
width: 50px;
background-color: white;
border: 5px dotted white;
padding: 3px 5px;
margin: 0px 10px;
}

How to hide a flexbox element with smoth effect

I need to center divs and hide them on each click, the problem is when I use hide() and flexbox it makes a rude effect after dissapear, but if you just simply float elements to left it makes fine, how can I achieve this?
I need to apply exactly the same disappearing effect that is in the
first example to the second one (with flexbox).
Here is the example:
$(".example1, .example2").click(function(){
$(this).hide("slow")
});
.main{
border: 2px solid black;
height: 100%;
width: 100%;
}
.example1{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
}
.example2{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
text-align: center;
margin-left: 8px;
}
.second{
border: 2px solid black;
display: flex;
display: -webkit-flex;
flex-wrap: wrap;
-webkit-flex-wrap: wrap;
justify-content: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main">
With simple float left it hides slowly fine:
<div class="first">
<div class="example1">1</div>
<div class="example1">2</div>
<div class="example1">3</div>
<div class="example1">4</div>
<div class="example1">5</div>
<div class="example1">6</div>
<div class="example1">7</div>
<div class="example1">8</div>
<div class="example1">9</div>
<div class="example1">10</div>
<div class="example1">11</div>
<div class="example1">12</div>
<div class="example1">12</div>
<div class="example1">13</div>
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br>
Now flex center, when you hide it makes rude effect, it isnt like div.example1:
<div class="second">
<div class="example2">1</div>
<div class="example2">2</div>
<div class="example2">3</div>
<div class="example2">4</div>
<div class="example2">5</div>
<div class="example2">6</div>
<div class="example2">7</div>
<div class="example2">8</div>
<div class="example2">9</div>
<div class="example2">10</div>
<div class="example2">11</div>
<div class="example2">12</div>
<div class="example2">13</div>
<div class="example2">14</div>
</div>
</div>

Use flex-start for justify content instead of center. Now it has the same effect as with float. You can also use fadeOut instead of hide to achieve effect you want.
$(".example1, .example2").click(function(){
$(this).fadeOut("slow")
});
.main{
border: 2px solid black;
height: 100%;
width: 100%;
}
.example1{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
}
.example2{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
display: flex;
justify-content: flex-start;
text-align: center;
margin-left: 8px;
}
.second{
border: 2px solid black;
display: flex;
display: -webkit-flex;
flex-wrap: wrap;
-webkit-flex-wrap: wrap;
justify-content: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main">
With simple float left it hides slowly fine:
<div class="first">
<div class="example1">1</div>
<div class="example1">2</div>
<div class="example1">3</div>
<div class="example1">4</div>
<div class="example1">5</div>
<div class="example1">6</div>
<div class="example1">7</div>
<div class="example1">8</div>
<div class="example1">9</div>
<div class="example1">10</div>
<div class="example1">11</div>
<div class="example1">12</div>
<div class="example1">12</div>
<div class="example1">13</div>
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br>
Now flex center, when you hide it makes rude effect, it isnt like div.example1:
<div class="second">
<div class="example2">1</div>
<div class="example2">2</div>
<div class="example2">3</div>
<div class="example2">4</div>
<div class="example2">5</div>
<div class="example2">6</div>
<div class="example2">7</div>
<div class="example2">8</div>
<div class="example2">9</div>
<div class="example2">10</div>
<div class="example2">11</div>
<div class="example2">12</div>
<div class="example2">13</div>
<div class="example2">14</div>
</div>
</div>

First, you can notice that this issue doesn't happen when you try to remove an item from the last row (excluding the first one in the last row). The issue appears when the first element of the row n suddenly go to the row n-1 because of 2 things :
You are trying to remove this first element so its width is going to 0 then for sure he will be able to fit into the previous row.
You are trying to remove any element so its width is going to 0 and you are creating enough space for the first element of next row to jump on it.
And this is simply due to center alignment as there is no difference if you do it with float, inline-block or flex. What is happening is that during the transition all the elements are moving to the center and when the new element comes (the first one of the next row) all the elements are re-placed again to keep the center alignement and then you have the rude effect !
With left alignment all the elements will move to the left during the transition and they won't move again at the end of transition (when the new element comes) so we don't have any rude effect.
Here is a snippet that shows inline-block and flex working fine with left alignment :
$(".example2, .example1").click(function() {
$(this).hide("slow");
});
.main {
border: 2px solid black;
height: 100%;
width: 100%;
}
.example1 {
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
text-align: center;
display:inline-block;
margin: 8px;
transition:margin 0.6s;
}
.example2 {
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
text-align: center;
float:left;
display:inline-block;

transition:margin 0.6s;
}
.first {

Unfortunately, I don't have a solution to this if you want to only use the hide() of jQuery. Maybe some ideas of solution is to make a more complex code that will avoid the centered elements to move in two directions (you may for example change margin property at the same time to cancel the movement) or you can keep the left alignment and find some trick to simulate the centering (dynamically add some margin when window resize for example).
Hope this will help you to investigate more (even if I didn't really give a solution).

Well as pointed out already it would require some kind of "physics engine" moving the other blocks up smoothly etc.
But I made an attempt anyway which looks a bit more smooth at least.
$(".example1, .example2").click(function(){
var time = 600;
var $parent = $(this).parent();
$parent.animate({'width': '90%'}, time/2, function() {
$parent.animate({'width': '100%'}, time/2);
});
$(this).hide(time);
});
.main{
border: 2px solid black;
height: 100%;
width: 100%;
}
.example1{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
}
.example2{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
text-align: center;
margin-left: 8px;
}
.second{
display: flex;
display: -webkit-flex;
flex-wrap: wrap;
-webkit-flex-wrap: wrap;
justify-content: center;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main">
<div class="second">
<div class="example2">1</div>
<div class="example2">2</div>
<div class="example2">3</div>
<div class="example2">4</div>
<div class="example2">5</div>
<div class="example2">6</div>
<div class="example2">7</div>
<div class="example2">8</div>
<div class="example2">9</div>
<div class="example2">10</div>
<div class="example2">11</div>
<div class="example2">12</div>
<div class="example2">13</div>
<div class="example2">14</div>
</div>
</div>

You can achieve the above without flex by making the children div's as inline-block with the parent being set with text-align:center, please take a look at this.
$(".example1, .example2").click(function(){
$(this).fadeOut("slow");
});
.main{
border: 2px dotted black;
height: 100%;
width: 100%;
}
.example1{
display: inline-block;
background-color: steelblue;
color: #FFF;
cursor: pointer;
margin: 10px;
padding: 15px 20px;
}
.first{
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<div class="main">
<div class="first">
<div class="example1">1</div>
<div class="example1">2</div>
<div class="example1">3</div>
<div class="example1">4</div>
<div class="example1">5</div>
<div class="example1">6</div>
<div class="example1">7</div>
<div class="example1">8</div>
<div class="example1">9</div>
<div class="example1">10</div>
<div class="example1">11</div>
<div class="example1">12</div>
<div class="example1">12</div>
<div class="example1">13</div>
</div>
</div>

My idea is: fade the whole parent container during reordering.
The effect will not so rude.
$(".second div").click(function() {
$(this).hide("slow");
var p = $(this).parent();
p.addClass("hidden");
setTimeout(function() {
p.removeClass("hidden")
}, 300);
});
p {
clear: both;
}
.second {
display: flex;
flex-wrap: wrap;
justify-content: center;
border: 2px solid black;
transition: 200ms;
}
.second div {
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
}
.hidden {
opacity: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="second">
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
<div>5</div>
<div>6</div>
<div>7</div>
<div>8</div>

<div>12</div>
<div>13</div>
<div>14</div>

Instead of justify-content: center I changed it to justify-content: space-evenly (in your case, looks somewhat similar to center only) also updated the function from simply hiding to .animate and then .hide. Will it do?
$(".example1, .example2").click(function(){
var _this = this;
$(_this).animate({width: "0"}, 500, function(){ $(_this).hide(500) })
});
.main{
border: 2px solid black;
height: 100%;
width: 100%;
}
.example1{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
}
.example2{
background-color: grey;
width: 50px;
height: 50px;
margin: 10px;
float: left;
text-align: center;
margin-left: 8px;
overflow: hidden;
}
.second{
border: 2px solid black;
display: flex;
display: -webkit-flex;
flex-wrap: wrap;
-webkit-flex-wrap: wrap;
justify-content: space-evenly;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="main">
With simple float left it hides slowly fine:
<div class="first">
<div class="example1">1</div>
<div class="example1">2</div>
<div class="example1">3</div>
<div class="example1">4</div>
<div class="example1">5</div>
<div class="example1">6</div>
<div class="example1">7</div>
<div class="example1">8</div>
<div class="example1">9</div>
<div class="example1">10</div>
<div class="example1">11</div>
<div class="example1">12</div>
<div class="example1">12</div>
<div class="example1">13</div>
<div>
<br><br><br><br><br><br><br><br><br><br><br><br><br>
Now flex center, when you hide it makes rude effect, it isnt like div.example1:
<div class="second">
<div class="example2">1</div>
<div class="example2">2</div>
<div class="example2">3</div>
<div class="example2">4</div>
<div class="example2">5</div>
<div class="example2">6</div>
<div class="example2">7</div>
<div class="example2">8</div>
<div class="example2">9</div>
<div class="example2">10</div>
<div class="example2">11</div>
<div class="example2">12</div>
<div class="example2">13</div>
<div class="example2">14</div>
</div>
</div>

Centering content of div in a container

In my website, i have a series of divs like this:
.box{
float:left;
width:143px;
height:183px;
overflow:hidden;
}
These divs are inside a simple container like this:
.container{
margin:70px 190px 0 190px;
overflow:hidden;
}
I would realize a responsive layout but the divs are not horizontal centered in the container. I tried to add "margin-left:auto;" and "margin-right:auto" but nothing. I have a layout as this:
Instead, i would a layout as this:
Can someone help me?

Solution using FlexBox.
FlexBox Guide
FlexBox Browsers Compatibility
.container {
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: space-around;
margin:7px 19px 0 19px;
background-color: red;
}
.box {
width:143px;
height:183px;
margin: 10px;
background-color: black;
}
<div class="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>

See this fiddle
You can achieve this using display:inline-block;, So kindly remove the float:left used in your CSS.
I have made an example like below,
HTML
<div class="container">
<div class="div1">
</div>
<div class="div1">
</div>
<div class="div1">
</div>
<div class="div1">
</div>
</div>
CSS
.div1{
margin:10px;
width:25%;
height:100px;
display:inline-block;
background-color:red;
}

You can not achieve this using float. You can use display: inline-block.
.box{
width:143px;
height:183px;
overflow:hidden;
display: inline-block;
}
.container{
margin:70px 190px 0 190px;
overflow:hidden;
text-align: center;
}

*{
padding: 0;
margin: 0;
box-sizing: border-box;
}
.container{
overflow: hidden;
max-width: 500px;
margin: 0 auto;
}
.box{
float:left;
width: 31%;
height: 183px;
background: #f00;
margin: 1%;
}
<div class="container">
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>
</div>
