I am trying to display divs with some information after a client clicks on a small dot-like div (7x7px black background) pointing to a place on a map. It works but the distance between the dot-like div and the information div is different in every dot-information couple.
Here is the HTML/JS script. Please, don't mind that all the JavaScript and CSS are in the same file, it is done for the sake of simplicity and will be changed lately.
<html>
<head>
<meta charset="utf8" />
</head>
<body>
<div id="pointer_div"
onclick="getClickPosition(event)"
style="position:absolute; top:1px; left:1px; border: 1px solid black;
background-repeat: no-repeat; width: 1146px; height: 714px;" >
<div id="sofia"
onclick="showForecast('Sofia_381_178')"
style="position:relative; top: 381px; left: 178px;
background:black; width: 7px; height: 7px;" ></div>
<div id="plovdiv"
onclick="showForecast('Plovdiv_512_435')"
style="position:relative; top: 512px; left: 435px;
background:black; width: 7px; height: 7px;" ></div>
<div id="ruse"
onclick="showForecast('Ruse_77_662')"
style="position:relative; top: 77px; left: 662px;
background:black; width: 7px; height: 7px;" ></div>
<div id="result_data"
style="visibility:hidden; width:300px; height:100px;
border: 1px solid black; background:white;"/></div>
</div>
<script language="JavaScript">
function showForecast (strr) {
var splits = strr.split('_');
var xcoord = splits[2];
var ycoord = splits[1];
if (xcoord>810) xcoord= xcoord-300;
if (ycoord>610) ycoord= ycoord-100;
var resultDiv= document.getElementById("result_data");
resultDiv.style.visibility="visible";
resultDiv.style.position = "relative";
resultDiv.style.left = xcoord;
resultDiv.style.top = ycoord;
resultDiv.innerHTML = 'Forecast for: ' + splits[0];
};
</script>
</body>
</html>
So, when I click on div "plovdiv", info div appears some 30px below the dot-div, but when I click "ruse" the info div shows right below the dot. I checked both in Firefox and SeaMonkey browsers and they behave identically.
I tried to put the script in jsfiddle but it was showing all the info divs at the top left of the page and I couldn't fix that. Here it is anyway, if anyone is interested jsfiddle.
The coordinates for the info divs are passed to the JS function in a string, and they are the same as those of the dot divs (one of the reasons I kept the css in the html file). I hope someone with better understanding of JS will be able to explain that.
It's because you are using position:relative on your divs, which moves them from the position they would be in by default. So (because divs are a block element) ruse would be under plovdiv which would be under sofia, then they are moved by the top and left values. Make them all position: absolute and they'll behave uniformly.
Here's your code working in jsfiddle(I added px units to your js): https://jsfiddle.net/wkz6dj04/5/
#sofia {
position: absolute;
top: 381px;
left: 178px;
background: black;
width: 7px;
height: 7px;
}
#plovdiv {
position: absolute;
top: 512px;
left: 435px;
background: black;
width: 7px;
height: 7px;
}
#ruse {
position: absolute;
top: 77px;
left: 662px;
background: black;
width: 7px;
height: 7px;
}
Here's the code working with the above modifications: https://jsfiddle.net/wkz6dj04/6/
If you want the gap back in, I suggest using margin-top on your #result_data like in this fiddle: https://jsfiddle.net/wkz6dj04/7/

I am currently trying to center a rectangle in an image with only using javascript (no css center properties). However, even if the numbers are right, the showing is wrong.
To do this, I use the following code :
$(document).ready(function() {
$(".img-zoom-container").css("width", $("#myimage").width());
$(".img-zoom-container").css("height", $("#myimage").height());
$("#lens_container").css("width", ($("#myimage").width() - $("#lens").width()));
$("#lens_container").css("height", ($("#myimage").height() - $("#lens").height()));
$("#lens_container").css("top", ($("#lens").height() / 2));
$("#lens_container").css("left", ($("#lens").width() / 2));
});
.img-zoom-container
{
border: 1px solid red;
}
#lens
{
border: 1px solid white;
width: 50px;
height: 50px;
position: absolute;
}
#lens_container
{
border: 1px solid cyan;
position: absolute;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="img-zoom-container">
<div id="lens"></div>
<div id="lens_container"></div>
<img id="myimage" src="https://via.placeholder.com/600x160.png?text=Testing Image" alt="">
</div>
The item I am trying to center is the #lens_container div (appears blue on screen). I also have a white square (#lens div) of size 50px by 50px. I would like to center and to size the blue rectangle in order to have half of the square width at each side of the blue rectangle and same with height. However, as you can see when trying the code, it is not the case although the maths are correct.
I do not know if you can understand my needs, but I would really appreciate help there.
Thanks in advance.
There are 2 issues:
First, position: absolute means to position the item "to its closest positioned ancestor, if any; otherwise, it is placed relative to the initial containing block" (reference). The parent element ".img-zoom-container" is not positioned. The initial container block would be <body>, which has some padding by default.
So your #lens_container is positioned relative to <body> of the iframe, which is probably not what you expected. Moreover, <body> by default has a non-zero padding size. You may see it clearer if you simply use CSS to position everything to top: 0 and left: 0:
body {
background-color: rgba(0, 0, 0, 0.1);
}
.img-zoom-container
{
border: 1px solid red;
width: 600px;
height: 160px;
}
#lens
{
border: 1px solid white;
width: 50px;
height: 50px;
position: absolute;
top: 0;
left: 0;
}
#lens_container
{
border: 1px solid cyan;
width: 550px;
height: 110px;
position: absolute;
top: 0;
left: 0;
}
<div class="img-zoom-container">
<div id="lens"></div>
<div id="lens_container"></div>
<img id="myimage" src="https://via.placeholder.com/600x160.png?text=Testing Image" alt="">
</div>
To have both #lens and #lens_container positioned relative to .img-zoom-container, you have to give .img-zoom-container a "position" value so it can be the "position ancestor":
$(document).ready(function() {
$(".img-zoom-container").css("width", $("#myimage").width());
$(".img-zoom-container").css("height", $("#myimage").height());
$("#lens_container").css("width", ($("#myimage").width() - $("#lens").width()));
$("#lens_container").css("height", ($("#myimage").height() - $("#lens").height()));
$("#lens_container").css("top", ($("#lens").height() / 2));
$("#lens_container").css("left", ($("#lens").width() / 2));
});
.img-zoom-container
{
border: 1px solid red;
position: relative; /** this line **/
}
#lens
{
border: 1px solid white;
width: 50px;
height: 50px;
position: absolute;
}
#lens_container
{
border: 1px solid cyan;
position: absolute;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="img-zoom-container">
<div id="lens"></div>
<div id="lens_container"></div>
<img id="myimage" src="https://via.placeholder.com/600x160.png?text=Testing Image" alt="">
</div>
It's still 1-2 pixels off. That is because you didn't take the border width into consideration (your second issue). You'd get a better result once you clear your head and think how you want the border widths to behave.
Depending on its container, you could just set an ID on your div like:
CONTENT .
Then in javascript, if there is an event to center it, you could make a function like:
function centerDivItem() {
document.getElementById("id1").style.alignContent = "center"
}
And then, as I said, call it from another place.
I need to put a google maps into a div and this one must be a circular div, but I've two problem
at load time I see standard rectangular div and after half second this div became circular
when use this map in draggable way I see always a standard div and only after mouse leave I see circle again
I think that the main idea is the order of loading files in your site: html, css, js.
Take a look at this: http://jsfiddle.net/nfng1sm4/
. You only have to change the background color in to the color of your container div.
.circle-text, #googleMap {
width: 500px;
height: 380px;
-moz-border-radius: 50%;
-webkit-border-radius: 50%;
border-radius: 50%;
background: #4679BD;}
adding css position: relative;, z-index: and border-radius to the parent div of the map holder, it will mask the child div(#mapCanvas)
Fiddle demo
css
.mapCover {
position: relative;
width: 300px;
height: 300px;
border: 5px solid #000000;
border-radius: 400px;
overflow: hidden;
z-index: 1000;
}
#mapCanvas {
width: 300px;
height: 300px;
}
html
<div class="mapCover">
<div id="mapCanvas"></div>

I am currently in the process of developing an online shop via wordpress. Everything was working fine, now I wanted to give my page a custom border( inverted round corners) and found the css code for it as seen here:
css:
body {
background-color: #fff;
}
.wrapper {
overflow:hidden;
width:200px;
height:200px;
}
div.inverted-corner {
box-sizing:border-box;
position: relative;
background-color: #3e2a4f;
height: 200px;
width: 200px;
border: solid grey 7px;
}
.top, .bottom {
position: absolute;
width: 100%;
height: 100%;
top:0;
left:0;
}
.top:before, .top:after, .bottom:before, .bottom:after{
content:" ";
position:absolute;
width: 40px;
height: 40px;
background-color: #fff;
border: solid grey 7px;
border-radius: 20px;
}
.top:before {
top:-35px;
left:-35px;
}
.top:after {
top: -35px;
right: -35px;
box-shadow: inset 1px 1px 1px grey;
}
.bottom:before {
bottom:-35px;
left:-35px;
}
.bottom:after {
bottom: -35px;
right: -35px;
box-shadow: inset 1px 1px 1px grey;
}
html:
<div class="wrapper">
<div class="inverted-corner">
<div class="top"> </div>
<h1>Hello</h1>
<div class="bottom"> </div>
</div>
</div>
I renamed the classes to get no conflict with the existing css classes of the theme. It is working fine as seen here:my site. The problem is now, that I cannot interact with the site anymore, no links, no hover effects. It seems like the custom css is overlaying the actual site. Do you have any suggestions what I maybe did wrong?
P.S. I edited the header.php so that inverted corner div and the top div are right underneath the page-wrapper div( site content) and in the footer.php I edited the top div and the inverted-corner div closing right above the page-wrapper div closing.
Add :
pointer-events: none;
to the .bottom-corner CSS, so the mouse passes through.
In your custom.css you have this:
.top-corner, .bottom-corner {
position: absolute;
width: 100%;
height: 100%;
top:0;
left:0;
}
This basically overlays the whole page and thus disables any interaction.
One other option I would like to suggest to change following css rule
CSS
.top-corner, .bottom-corner {
position: absolute;
width: 100%;
height: 100%;
top:0;
left:0;
}
Replace above code with the below one
.top - corner, .bottom - corner {
position: absolute;
width: 100 % ;
}
this solution will work on all modern browsers and IE8 and above ( I'm not sure about lower version of IE, but it may work on them as well )
I've just wrote a page with couple div-s and little CSS and javascript.
I don't know how to insert scroll bar into one of my div.
Code is not that hard to understand. CSS and javascript are included in code.
<html>
<head>
<style>
#container
{
vertical-align: top;
width: 98%;
height: 90%;
padding: 5px;
}
#discussion {
width: 99%;
height: 90%;
overflow-y: scroll;
border: 1px solid #ccc;
padding: 5px;
text-align: left;
/*position: absolute; bottom: 0; left: 0;*/
position: relative;
}
#content
{
overflow-y: auto;
position: absolute; bottom: 0; left: 0;
}
#message {
width: 100%;
vertical-align:bottom;
padding: 5px;
border: 1px solid #ccc;
}
</style>
<script>
function init(){
var message = $('#message');
var content = $('#content');
message.keypress(function (e) {
if (e.keyCode == 13 && message.val().length > 0) {
content.append(message.val() + "<br/>");
//content.scrollTop(discussion.get(0).scrollHeight); //works fine with top to down
message.val('').focus();
}
});
};
</script>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body onload="javascript:init();">
<div id="container">
<div id="discussion">
<div id="content"></div>
</div>
<input id="message" type="text" placeholder="Hit Enter button to insert"/>
</div>
</body>
</html>
I need scroll bar when content gets out of discussion section.
Thing is when I insert some text with from top to bottom flow scroll bar works fine.
Unfortunately, all text has to be inserted from bottom to top flow.

You set the height to 90%, but it doesn't know what it's 90% of.
If you want it set to 90% of the body, you'll need to set html,body {height: 100%;}.
Then you need to remove the absolute positioning you put on the content.
Working fiddle here: http://jsfiddle.net/davidpauljunior/2PpqN/
The main cause for the problem is you missed to set the width and height for #content div.
So add it
width: 100%;
height: 100%;
Also for the parent element discussion, instead of using % value stick to static values for height so that user can view it. Currently it is very small to view the scroll.
width: 100%;
height: 200px;
JSFiddle
Hope you understand.
You need to remove overflow from #discussion and change postion to relative in #content
CSS
#discussion {
width: 99%;
height: 90%;
border: 1px solid #ccc;
padding: 5px;
text-align: left;
/*position: absolute; bottom: 0; left: 0;*/
position: relative;
}
#content
{
overflow: auto;
position: relative;
height:100px;
width:100%;
}

I would like to do something with my document which is quite unique (haven't seen it before) and thus maybe not even possible.
What I would like is to have a div which will overlay everything in the document, maybe give it background black so that nothing is visible. Second I would like to have a small squire window in the overlay which doesn't share the black background, in fact it is somewhat transparent and therefore it would be possible to 'peek' trough that window to see document content. But only the content where this window is. It would be kinda like those "zoom" plugins in which only a small portion is being zoomed, but in this case it would show specific content. Any idea how to create such a thing?
An example of what you can do is the following (it may not be the best but it works)
HTML
<div id='peakview'></div> <!-- This div is your view window -->
<div id='out'>
<div class='overlay'></div>
<div class='overlay'></div>
<div class='overlay'></div>
<div class='overlay'></div>
</div>
The <div> inside of #out will re-size accordingly to the position of #peakview creating the illusion of a full overlay. This can be done with simple css and some calculus.
Mainly what you need is the position of the element on screen.
var h = $(this).offset().top;
var l = $(this).offset().left;
var r = ($(window).width() - ($(this).offset().left + $(this).outerWidth()));
//right offset
var b = ($(window).height() - ($(this).offset().top + $(this).outerWidth()));
//bottom offset
In my example I used .draggable() from jQuery UI to move the div around. And while dragging the 4 divs shown above are adjusting their height and width to fill up the space between #peakview and document border.
An example for the first div
$('.overlay:eq(0)').css({
top: 0,
left: 0,
width: '100%',
height: h //the height is always changing depending on the #peakview .offset().top
});
In this fiddle you will see how the filling divs behave
Another ruff start:
http://jsfiddle.net/XDrSA/
This require some extra work, but it may suit your needs.
HTML:
<div id="yourContent" style="width: 300px; margin:100px auto;">
<input type="button" id="zoom" value="Click to zoom"/>
</div>
<div id="zoomer">
<div id="window">This is your "window"</div>
<div id="overlay_top"></div>
<div id="overlay_left"></div>
<div id="overlay_right"></div>
<div id="overlay_bottom"></div>
</div>
CSS:
body {
margin:0;
padding:0;
}
#zoomer {
height: 100%;
width: 100%;
position: absolute;
top: 0;
display: none;
}
#overlay_top {
height: 20%;
width: 100%;
background-color: black;
position: absolute;
top: 0
}
#overlay_right {
height: 100%;
width: 20%;
background-color: black;
position: absolute;
right: 0;
}
#overlay_left {
height: 100%;
width: 20%;
background-color: black;
position: absolute;
left: 0;
}
#overlay_bottom {
height: 20%;
width: 100%;
background-color: black;
position: absolute;
bottom: 0;
}
#window {
margin: 0 auto;
height: 100%;
width: 80%;
position: absolute;
background-color: rgba(0,0,0,.5);
}
And a piece of javascript:
$('#zoom').click(function() {
$('#zoomer').fadeIn();
});
You may need to stumble with the positioning, and the window will be a fixed size one. Not draggable though.
