I'm making a website with a FlipClock countdown. By default it is too small. It has to be scaled using transform: scale() or zoom, changing the width and height property only increases the amount of white around the countdown.
On a screen not 1920*1080 the clock is not correctly sized.
I've tried some JS scalers, however these use pixel size to scale, so it doesn't work. I've also tried a simple viewport.
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/flipclock/0.7.8/flipclock.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/flipclock/0.7.8/flipclock.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<div class="clock" style="margin:2em; transform: scale(2.5);"></div>
<script type="text/javascript">
var clock;
$(document).ready(function() {
var currentDate = new Date();
var futureDate = new Date("Dec 24, 2019 00:00:00");
var diff = futureDate.getTime() / 1000 - currentDate.getTime() / 1000;
// Instantiate a coutdown FlipClock
clock = $('.clock').FlipClock(diff, {
clockFace: 'DailyCounter',
countdown: true,
});
});
</script>
I found a way to do what I wanted using JS.
let perpx = 2.5/1920;
let ratio = perpx * window.screen.width;
document.getElementById('clock').style.transform = "scale(" + ratio + ")";

I wonder how can I use css/javascript to adjust the blinking cursor inside the search box with CSS?
Is it possible to replace default blinkig caret to horizontal blinking icon
I don't think it is so hard. I made a quick example, which works in most modern browsers except Safari.
It draws the caret on a canvas, and sets it as a background of the input, on a position calculated from the browsers caret position.
It checks if the browser supports the caret-color css property, and if it doesn't it doesn't do anything, because both the system caret, and our caret will be visible in the same time. From the browsers I tested, only Safari doesn't support it.
$("input").on('change blur mouseup focus keydown keyup', function(evt) {
var $el = $(evt.target);
//check if the carret can be hidden
//AFAIK from the modern mainstream browsers
//only Safari doesn't support caret-color
if (!$el.css("caret-color")) return;
var caretIndex = $el[0].selectionStart;
var textBeforeCarret = $el.val().substring(0, caretIndex);
var bgr = getBackgroundStyle($el, textBeforeCarret);
$el.css("background", bgr);
clearInterval(window.blinkInterval);
//just an examplethis should be in a module scope, not on window level
window.blinkInterval = setInterval(blink, 600);
})
function blink() {
$("input").each((index, el) => {
var $el = $(el);
if ($el.css("background-blend-mode") != "normal") {
$el.css("background-blend-mode", "normal");
} else {
$el.css("background-blend-mode", "color-burn");
}
});
}
function getBackgroundStyle($el, text) {
var fontSize = $el.css("font-size");
var fontFamily = $el.css("font-family");
var font = fontSize + " " + fontFamily;
var canvas = $el.data("carretCanvas");
//cache the canvas for performance reasons
//it is a good idea to invalidate if the input size changes because of the browser text resize/zoom)
if (canvas == null) {
canvas = document.createElement("canvas");
$el.data("carretCanvas", canvas);
var ctx = canvas.getContext("2d");
ctx.font = font;
ctx.strokeStyle = $el.css("color");
ctx.lineWidth = Math.ceil(parseInt(fontSize) / 5);
ctx.beginPath();
ctx.moveTo(0, 0);
//aproximate width of the caret
ctx.lineTo(parseInt(fontSize) / 2, 0);
ctx.stroke();
}
var offsetLeft = canvas.getContext("2d").measureText(text).width + parseInt($el.css("padding-left"));
return "#fff url(" + canvas.toDataURL() + ") no-repeat " +
(offsetLeft - $el.scrollLeft()) + "px " +
($el.height() + parseInt($el.css("padding-top"))) + "px";
}
input {
caret-color: transparent;
padding: 3px;
font-size: 15px;
color: #2795EE;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" />
If there is interest, I can clean it a bit and wrap it in a jQuery plugin.
Edit: forgot about the blinking, so I added it. A better way will be to add it as css animation, in this case the caret should be in a separate html element positioned over the input.
Changing the color of the caret is supported by the latest standards. But not changing its width is not, which I think is a shame because it is a question of accessibility for vision-impaired people.
One approach for implementing such a change yourself is first trying to figure out what is the position the caret is blinking at, then overlaying it with an element that looks like the caret but is perhaps wider etc.
Here's an article on how to go about doing such a thing. It's a good article but the end-solution is kind of complicated as a whole. But see if it solves your problem:

Here is perhaps a simpler explanation for how to find the care x-y position:
How do I get the (x, y) pixel coordinates of the caret in text boxes?
I'm using primefaces ronin theme and I'm trying to make a full screen gmap no matter what the resolution of the screen is. how ever, unless I state the height in pixels, it won't work.
for example, if i set the height css attribute of the map to 100%, it doesn't show, and if I wrap the gmap with a div container with 100% height, it still doesn't work. how can I make a full screen responsive gmap?
You can show a full screen responsive p:gmap on following way:
Lets assume that p:gmap is defined like this (no need for style attribute)
<p:gmap id="gmap" center="41.381542, 2.122893" zoom="13" type="hybrid" />
Place following JavaScript on your page that will do the trick
<script>
function resizeElement(elementId,width,height){
console.log("Resizing element " + elementId + " W/H="+ width + "/" + height);
var element = document.getElementById(elementId);
element.style.width=width+"px";
element.style.height=height+"px"
}
function resizePfGmapFullScreen() {
var width = window.innerWidth - 20;
var height = window.innerHeight - 20;
resizeElement("gmap", width, height);
}
window.onload = function() {
window.dispatchEvent(new Event('resize'));
};
window.onresize = function(event) {
console.log("Screen is resized");
resizePfGmapFullScreen();
};
</script>
Advantage of this solution is that p:map will be automatically resized when screen is resized including screen orientation change on mobile devices.
It is tested running on the latest Primefaces version 6.1.
My present code doesn't work and i have a unexpected token error :
<script type="text/javascript">
var myWidth = (window.screen.availWidth - 100);
document.write("
#test {
width:" + myWidth +"px;
}
");
</script>
what's wrong ?
And, i would like to know if this is a correct way : i made a menu like http://blog.tomri.ch/super-simple-off-canvas-menu-navigation/ , displayed starting at the left ro the right, and i don't want to hide a button who has 100px width, (% width can't be appropriate). so, i do this for calculate width. It's a good way ? (i use html5/angularjs for android application).
Proper way
<p id="demo">Click the button to return the available width of your screen.</p>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction()
{
var x = "Available Width: " + screen.availWidth + "px";
document.getElementById("demo").innerHTML=x;
}
</script>
I have this site in development, http://melanie.3drexstaging.com/
The client wants the background to scale up or down (to a point) depending on the browser size.
I have gotten it to work halfway decent with some jquery hacks to adjust sizing of elements as the browser resizes, but I would much prefer a css only option.
We have 3 images, one is the fixed aspect ratio center image that should always show in entirety, and to the left and right we have the images that continue the pattern.
Thanks in advance for any tips!
My SAD javascript hacks:
<script type="text/javascript">
$(document).ready(function () {
fixBg();
});
$(window).load(function () {
fixBg();
});
$(window).resize(function () {
fixBg();
});
function fixBg()
{
var mh = Math.max($(window).height(), 768);
if ($("#ControlBar").length > 0) {
mh -= 54;
}
var mw = Math.round((mh / 768) * 1264);
var winW = Math.max(1264, $(window).width());
$("#bgCenter").height(mh).width(mw);
$("#shade").height(mh).width(mw).css("left", ((winW - mw) / 2) + 10);
var extra = ((winW - mw) / 2) + 10;
$(".bgFillers").width(extra).height(mh);
var bgw = (mh / 768) * 360;
$(".bgFillers").css("background-size", bgw + "px " + mh + "px");
//$("#siteContent").css("min-height", mh - $("#header").height() - $("#footer").height() - 20);
}
</script>
And the basic markup:
<div id="master">
<div id="bg">
<div id="bgLeft" class="bgs bgFillers"></div>
<div id="bgCenter" class="bgs">
</div>
<div id="bgRight" class="bgs bgFillers"></div>
</div>
<div id="shade"></div>
<div id="centeredSite">
</div>
</div>
have you tried making the size relative?
you just use % instead of px (or any other option)
100% is full element, 50% is half your element (if you put it in a div you set to 50% it'll take half of the div that's taking up half of your page, so 1/4th of your page)
otherwise i'll need some more information
I have a page with multiple possible banners and a silverlight app below it. I want to size the silverlight app so that it's height is always 100% of the available screen height minus the height of the banner so that there are never any scroll bars on the page. How would I go about doing this?
<script type="text/javascript">
var scnWid,scnHei;
if (self.innerHeight) // all except Explorer
{
scnWid = self.innerWidth;
scnHei = self.innerHeight;
}
else if (document.documentElement && document.documentElement.clientHeight)
// Explorer 6 Strict Mode
{
scnWid = document.documentElement.clientWidth;
scnHei = document.documentElement.clientHeight;
}
else if (document.body) // other Explorers
{
scnWid = document.body.clientWidth;
scnHei = document.body.clientHeight;
}
var SilverLightAppHeight = scnHei - /* insert banner height here */;
</script>
then later when you want to set your form size
<script type="text/javascript">
document.getElementById('silverlightform').style.height = SilverLightAppHeight;
</script>
