Hide the "resizing" handle in a resizable div?

There are a few other questions which are similar, but none works or seems in the right area. I'm trying to make a table's columns' widths resizable. My table is a normal HTML table, except that it has the Bootstrap 4 class table (maybe they could have thought of a different name...!).
My css looks like this:
.resizable-div {
resize: horizontal;
overflow: auto;
margin: 0px;
padding: 0px;
border: 1px solid black;
display:block;
min-width: 100px;
min-height: 30px;
}
The relevant bit of JS where I add the cell to the table row with a resizable div inside it, and text inside that, is like this:
row.appendChild(cell);
const resizableTdDiv = document.createElement( 'div' );
resizableTdDiv.classList.add( 'resizable-div');
cell.appendChild( resizableTdDiv );
const cellTextNode = document.createTextNode(isHeader ? fieldName : value);
resizableTdDiv.appendChild(cellTextNode);
The result works fine: resizable columns. Hurrah. There is only one fly in the ointment:
I can get rid of the borders, of course. I just want to lose those pesky handler triangles in the bottom right corners... all of them!
I realise users have to be given an idea that they are able to resize the columns... but I'd be perfectly happy to do that some other way if I could replace those triangle icons with 100% transparent ones (for example).
Edit
Here's a JSFiddle! Amazingly easy to do!

You can do this in WebKit based browsers currently with the ::-webkit-resizer pseudo element.
div{
overflow:auto;
resize:both;
width:50%;
}
div:nth-of-type(2)::-webkit-resizer{
background:transparent;
}
<div>
Not Hidden
</div>
<div>
Hidden
</div>

WebKit provides a pseudo-element for this ::-webkit-resizer and you can hide those triangles by applying display: none, -webkit-appearance: none, or background: transparent.
For Firefox or anything without WebKit an alternative / workaround would be to position a custom handle over top of each resizable div. This may require some different markup though.
.wrapper {
position: relative;
display: inline-block;
}
.resizable-div {
position: relative;
resize: both;
overflow: auto;
margin: 0px;
padding: 0px;
border: 1px solid black;
display:block;
min-width: 100px;
min-height: 30px;
}
.handle {
position: absolute;
bottom: 0;
right: 0;
width: 20px;
height: 20px;
background: black;
pointer-events: none;
}
/* ::-webkit-resizer {
background: transparent;
} */
<div class="wrapper">
<div class="resizable-div"></div>
<div class="handle"></div>
</div>

How do I make google maps map mobile friendly?

I have a problem with the size of the google maps map.
What I would like is to have 100% width of the map and div paragraph. See image:
It works on computers as you can see. But it's not responsive width, and that is the problem.
CSS:
#map_canvas { // the map
height:600px;width:800px;
}
.google_map {
position:relative;
float: left;
}
.paragraph { // text and stuff on the right
float: left;
padding-left:5px;
display: inline;
}
HTML
<div class="google_map">
<div id="panel">
<div ><input onclick="deleteMarkers();" type=button value="Rensa"></div>
</div>
<div id="facit"></div>
<div id="map_canvas"></div>
</div>
<div class="paragraph">
blablabla
</div>
If I change the width of map_canvas to 100% the result is ~100 px.
I tried to create a div that holds both map_canvas and paragraph with the width 100% and then to set width of the map to XX% but that again got interpreted as xx px.
Because the map is 800 px wide it becomes very hard to use on mobiles, I have no problem with map_canvas comes above paragraph on mobiles if that is a solution.
In short I need on computers the width to be say 800px and on mobiles 100%.
EDIT:
#map_canvas {
width:100%;
min-height:600px;
}
Becomes:
EDIT:
CSS panel
#panel {
position: absolute;
top: 10px;
left: 65%;
margin-left: -180px;
z-index: 5;
background-color: #000;
padding: 5px;
}
#panel, .panel {
font-family: 'Roboto','sans-serif';
line-height: 20px;
padding-left: 5px;
}
#panel select, #panel input, .panel select, .panel input {
font-size: 15px;
}
#panel select, .panel select {
width: 100%;
}
#panel i, .panel i {
font-size: 12px;
}
#panel2 {
position: absolute;
top: 10px;
left: 73%;
margin-left: -180px;
z-index: 5;
background-color: #000;
padding: 5px;
}
#panel2, .panel {
font-family: 'Roboto','sans-serif';
line-height: 20px;
padding-left: 5px;
}
#panel2 select, #panel2 input, .panel select, .panel input {
font-size: 15px;
}
#panel2 select, .panel select {
width: 100%;
}
#panel2 i, .panel i {
font-size: 12px;
}
Panel is the button you see on the image, Panel2 is a button that appears when you click once on the map, positioned to the right of the first button.

Try this:
#map_canvas {
width:100%;
min-height:600px;
}
Hope this help.

You could use CSS3 #media tags in your CSS. Including those you are able to set the width of your map according to the screen size of the device. Take a closer look to this site if you want to determine which device is used. You can define specific rules after which certain parts of your CSS are included or not, depending on the conditions you define in your file. After including this your css file could look like this:
#media (max-width: 800px) {
#map_canvas{
/*youre custom style for devices which have a maximum
screen size of 800px and therefore
can not display your map correctly*/
}
}
You can read more about this topic at this site.
Note that you can also include media tags in your <link> tag like this:
<link rel="stylesheet" type="text/css" media="only screen and (max-device-width: 800px)" href="small-device.css" />
For more information you should take a closer look on this site.
Another way to determine which device is used is to use jQuery, JavaScript or PHP. Since current mobile device browsers should be able to use CSS3 I would recommend to use the media tags.

Expand the parent div of floated elements to fit their total width?

I am trying to put together a page that will have a horizontally scrolling pane on it - here is an example of the layout I am looking to get:
The content is dynamically added and has varying dimensions. .
Here's some HTML:
<div class="container">
<div class="inner">
<div></div>
<div></div>
<div></div>
</div>
</div>
Base CSS:
.container {
width: 100%;
height: 100%;
}
.container .inner {
position: relative
}
.container .inner > div {
float: left;
}
Currently the only way I can get it working is by setting an explicit width for .inner. Otherwise, closest I've come is this answer, but it's still pretty far off my desired effect. Is it possible to achieve what I'm looking for with HTML/CSS alone or will I have to resort to javascript?

Is this what you expected? http://jsfiddle.net/GE5Hf/4/
Just use white-space: nowrap together with the inline-block and vertical-align: top. You don't need your .inner div to achieve the desired effect - just use one container with overflow-x: auto:
<div class="container">
<div id="i1"></div>
<div id="i2"></div>
<div id="i3"></div>
</div>
CSS
.container {
width: 100%;
height: 100%;
overflow-x: auto;
white-space: nowrap;
}
.container > div {
display:inline-block;
vertical-align: top;
}
Note: it is better to use overflow-x: auto than scroll just in case the scrollbar is not needed.
EDIT: We were speculating whether you actually need that .inner div. If you need it, you can just add it back with no special style required: http://jsfiddle.net/GE5Hf/5/
EDIT 2: To have the .inner div the width as its children, simply give it display:inline-block: http://jsfiddle.net/GE5Hf/8/
EDIT 3: Tried what you suggested in your last deleted comment, i.e. remove the fixed width of the child. This was really tricky, I had to wrap each child element to special div with display: table-cell and the inner div gets dislay: table-row: http://jsfiddle.net/GE5Hf/12/

This can be done using CSS only.
Here's a jsFiddle.
The solution is to set position: relative; on .container, which creates a new stacking context inside the .container, setting position: absolute; and white-space: nowrap; on .inner ensures that .inner's content div's will not wrap to the next line and that .inner will grow with its content, adding display: inline-block; and vertical-align: top; on the .inner > div's ensures that they are treated as inline elements and stick to the top of their containing element.
I believe this is what you are after, I have checked on the latest versions of IE, Chrome, Firefox and Safari and it works fine on all of them, I have no reason to believe that it won't work on older versions.
HTML
<div class="container">
<div class="inner">
<div></div>
<div></div>
<div></div>
</div>
</div>
CSS
.container {
position: relative;
width: 220px;
height: 400px;
overflow-x: scroll;
}
.container .inner {
position: absolute;
white-space: nowrap;
background-color: #FFCCFF;
}
.container .inner > div {
vertical-align: top;
display: inline-block;
margin: 10px;
}

Is position: relative mandatory ?
.container .inner {
position: fixed;
overflow: hidden;
}
demo

#styke You can do that with display:inline-block(and some font-size on .inner > div) and font-size:0 to div.inner.Provided fiddle here: http://jsfiddle.net/zepva/4/ , ignore the colors, i used them only for demonstrationfont-size:0 will remove the gaps between the element using display:inline-block so when you will get the total width of the div.inner, that will be the sum of children divs

Take a look at this, no script was necessary:
.container {
width: 300px;
height: 100%;
background-color: silver;
}
.container .inner {
white-space:nowrap;
padding: 10px;
overflow-x: scroll;
background-color: gray;
}
.container .inner > div {
display: inline-block;
vertical-align:top;
background-color: red;
border: 1px solid black;
}
Demo: http://jsfiddle.net/er144/4FLWK/

display:inline-block, with vertical-align:top , that way your text wont fall at the bottom of the container.
.container .inner > div {
display:inline-block;
vertical-align:top;
}

How to align a website to the center of the screen top/bottom and right/left?

I want to have the effect like dropbox:https://www.dropbox.com/ where my website is centered in the exact middle of the page.

Achieving this effect is way more complicated than it should be. Here's a bare-bones working example: http://jsfiddle.net/JakobJingleheimer/UEsYM/
html, body { height: 100%; } // needed for vertical centre
html { width: 100%; } // needed for horizontal centre
body {
display: table; // needed for vertical centre
margin: 0 auto; // needed for horizontal centre
width: 50%; // needed for horizontal centre
}
.main-container {
background-color: #eee;
display: table-cell; // needed for vertical centre
height: 100%; // needed for vertical centre
// overflow: auto; // <- probably a good idea
vertical-align: middle; // needed for vertical centre
width: 100%; // needed for horizontal centre
}
.container {
background-color: #ccc;
padding: 20px;
}

If you want to achieve this:
Here are different methods, with the pros/cons of each one, for centering a page vertically. Choose which one you prefer:
http://blog.themeforest.net/tutorials/vertical-centering-with-css/
EDIT. As suggested, I will proceed to explain one of the methods. It only works if you already know the height/width of the element to center (the link includes more methods). Assuming all your content is within <body>, and that your content is 900px x 600px, you can do in your css:
html {
width: 100%;
height: 100%;
}
body {
width: 900px;
height: 600px;
position: absolute;
top: 50%;
margin-top: -300px; /* Half of the height of your body */
}
However, this falls short for dynamically generated content, since you don't know the height of it. I've used it succesfully on log-in box pop-up and settings pop-up.
Another method I've used in the past for the whole page is the Method 1 from the link. It makes a set of divs to behave as a table, which can vertical-align to the middle.

If you want to align it vertically center, please check this web page: http://www.jakpsatweb.cz/css/css-vertical-center-solution.html

If you know the width and height of your page
then wrap your contents in following div css
.center
{
position:absolute;
top:50%;
left:50%;
margin-left: -(yourPageWidth/2);
margin-top: -(YourPageHeight/2);
}

On your topmost div give margin:0 auto 0 auto; Also define some width to that div.

First create a main container of the desired width and then put all your code inside the main container. For Eg.
<body>
<div id="container">
......... your code
</div>
</body>
And in the css
#container{
width: 700px ;
margin-left: auto ;
margin-right: auto ;
}
You can change the width as per your needs

<body>
<div class="container">
......... your code
</div>
</body>
#container{
width: 700px ;
margin:0 auto ;
padding:0px;
}

Try this:
html
<span id="forceValign"></span><!--
--><div id="centerMiddleWrap">
<div id="centered">Hello this is some text. Hello this is some text. Hello this is some text.</div>
</div>
CSS
html {
height: 100%;
background: #eee;
}
body {
margin: 0;
height: 100%;
/*important*/
text-align: center;
}
#centerMiddleWrap {
/*important*/
display: inline-block;
vertical-align: middle;
}
#forceValign {
/*important*/
height: 100%;
display: inline-block;
vertical-align: middle;
}
#centered {
background: #000;
color: #fff;
font-size: 34px;
padding: 15px;
max-width: 50%;
/*important*/
display: inline-block;
}
Here is an demo

Wrap a div and define its width, use margin:0 auto for centering the div.
You can check a site's CSS by using Firebug or browser extensions.

Centring the whole web page (on a really wide site)?

I have a web page that is wide (3078px) and pretty long too (1540px).
The page has a large div containing 6 divs inside it on 3 columns and two rows (each row a separate div itself).
When the page loads, it displays the top left div (box1) in the top right corner, with the option to scroll down or right to see the rest of the content.
I'd like to make it be centered on load, that is to say, I would like the middle column (box 2) to show in the middle of the page when loading, with the option to scroll left and right for the rest of the content.
Is there any script or CSS/HTML combo that would allow me to select what will be displayed in the browser on load? Essentially, what I'm trying to do is similar to centring the whole of the body within the browser window. I was considering attaching an anchor with a name to the middle div (box2), but I still wouldn't know the Javascript to make it select that div as the top left to load on.
Please let me know if this is a bit confusing, I can make a sketch to explain what I mean if that could help! (The jsfiddle link is below)
HERE IS THE CSS:
body {
margin:0px;
padding:0px;
text-align: center;
background:black;
}
#box1, #box2, #box3, #box4, #box5, #box6 {
margin:0px;
padding:0px;
float:left;
display:inline-block;
width:1024px;
height:768px;
background:transparent;
border:1px red solid;
}
#above {
margin:0px;
padding:0px;
float:left;
display:inline-block;
width:3078px;
height:770px;
background:transparent;
}
#below {
margin:0px;
padding:0px;
float:left;
display:inline-block;
width:3078px;
height:770px;
background:transparent;
}
#mainbox {
margin: 0 auto;
padding:0px;
float:left;
display:inline-block;
width:3078px;
height:1540px;
background:transparent;
}
AND THE HTML:
<div id="mainbox">
<div id="above">
<div id="box1"></div>
<div id="box2"></div>
<div id="box3"></div>
</div>
<div id="below">
<div id="box4"></div>
<div id="box5"></div>
<div id="box6"></div>
</div>
</div>
There is a JS fiddle too: http://jsfiddle.net/KyMet/
A similar question would be (to remove the pain of horizontal scrolling) – If I have a really long page, which scrolls vertically, how can I get it so that it loads with the bottom of the page in the browser window, so that, practically, you need to scroll up to see the rest of the content?

You need to use some query to pull this of.
EDIT
DEMO
$(function(){
//total width of your wrapper
var totalWidth = $('#mainbox').outerWidth(true);
//width of the user browser
var width = window.innerWidth;
//calculate the middle
var middle = (totalWidth - width) / 2
window.scrollTo( middle, 0 );
});
YOUR CSS
I would also recommend you to clean up your css, there is a lot of unnecessary properties there. You can choose to use this
body {
margin: 0 auto;
padding: 0;
text-align: center;
background: #222;
overflow: scroll;
}
#box1, #box2, #box3, #box4, #box5, #box6 {
margin: 0;
padding: 0;
float: left;
display: block;
width: 1024px;
height: 768px;
border: 1px red solid;
}
#box2 {
background-color: aqua; /* only for demo */
}
#above {
margin: 0px;
padding: 0px;
display: block;
}
#below {
margin: 0px;
padding: 0px;
display: block;
}
#mainbox {
padding: 0;
width: 3078px;
height: 770px;
}
/* For modern browsers */
.clearfix:before,
.clearfix:after {
content:"";
display:table;
}
.clearfix:after {
clear:both;
}
/* For IE 6/7 (trigger hasLayout) */
.clearfix {
*zoom:1;
}

You would have to use jQuery scrollto library
