[jquery-ui] How to resize the jQuery DatePicker control

I'm using the jQuery DatePicker control for the first time. I've got it working on my form, but it's about twice as big as I would like, and about 1.5 times as big as the demo on the jQuery UI page. Is there some simple setting I'm missing to control the size?

Edit: I found a clue, but it opens up new problems. In the CSS file, it states the component will scale according to the parent element's font size. They recommend setting

body {font-size: 62.5%;}

to make 1em = 10px. Doing this gives me a nicely sized datepicker, but obviously it messes up the rest of my site (I currently have font-size: .9em).

I tried throwing a DIV around my text box and setting its font size, but it seems to ignore that. So there must be some way to shrink the datepicker by changing the font of its parent, but how do I do that without messing up the rest of my site?

This question is related to jquery-ui

The answer is


You don't have to change it in the jquery-ui css file (it can be confusing if you change the default files), it is enough if you add

div.ui-datepicker{
 font-size:10px;
}

in a stylesheet loaded after the ui-files

div.ui-datepicker is needed in case ui-widget is mentioned after ui-datepicker in the declaration


Add

div.ui-datepicker, .ui-datepicker td{
 font-size:10px;
}

in a stylesheet loaded after the ui-files. This will also resize the date items.


I was using an input to collect and show the calendar, and to be able to resize the calendar I have been using this code:

div.ui-datepicker, .ui-datepicker input{font-size:62.5%;}

It works like a charm.


with out changing the css file you can also change the calendar size  by putting the the following code in to ur <head>.....</head> tag:


<head>
<meta charset="utf-8" />
<title>jQuery UI Datepicker - Icon trigger</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css" />
<style type="text/css">
.ui-widget { font-family: Lucida Grande, Lucida Sans, Arial, sans-serif; font-size: 0.6em; }
</style>

<script>



$(function() {

$( "#datepicker" ).datepicker({
//font-size:10px;
 //numberOfMonths: 3,

showButtonPanel: true,
showOn: 'button',
buttonImage: "images/calendar1.gif",
buttonImageOnly: true
});
});
</script>

</head>

the best place to change the size of the calendar is in the file jquery-ui.css

/* Component containers
----------------------------------*/
.ui-widget {
    font-family: Verdana,Arial,sans-serif;
    font-size: .7em; /* <--default is 1.1em */
}

I change the following line in ui.theme.css:

.ui-widget { font-family: Trebuchet MS, Tahoma, Verdana, Arial, sans-serif; font-size: 1.1em; }

to:

.ui-widget { font-family: Trebuchet MS, Tahoma, Verdana, Arial, sans-serif; font-size: 12px; }

This worked for me and seems simple...

$(function() {
  $('#inlineDatepicker').datepicker({onSelect: showDate, defaultDate: '01/01/2010'});
});

<div style="font-size:75%";>
<div id="inlineDatepicker"></div>
</div>

I had datepicker appearing in a modal and because of the "date-display-container" on the left hand side, the calendar was partially out of view, so I added:

.datepicker-date-display {
  display: none;
}

.datepicker-calendar-container {
  max-height: 21em;
}
.datepicker-day-button {
  line-height: 1.2em;
}

.datepicker-table > thead > tr > th {
  padding: 0;
}

you can change jquery-ui-1.10.4.custom.css as follows

.ui-widget
{
    font-family: Lucida Grande,Lucida Sans,Arial,sans-serif;
    font-size: 0.6em;
}

To get this to work in Safari 5.1 with Rails 3.1, I had to add:

.ui-datepicker, .ui-datepicker a{
 font-size:10px;
}

$('div.ui-datepicker').css({ fontSize: '12px' }); work if we call it after $("#DueDate").datepicker();

Fiddle


open ui.all.css

at the end put

@import "ui.base.css";
@import "ui.theme.css";

div.ui-datepicker {
font-size: 62.5%; 
}

and go !


$('.ui-datepicker').css('font-size', $('.ui-datepicker').width() / 20 + 'px');


Not sure whether some body has suggested following way, if yes, just ignore my comments. I tested this today and it works for me. By just resizing the font before the control gets displayed:

$('#event_date').datepicker({
    showButtonPanel: true,
    dateFormat: "mm/dd/yy",
    beforeShow: function(){    
           $(".ui-datepicker").css('font-size', 12) 
    }
});

Using the callback function beforeShow


I think I found it - I had to go into the CSS file and change the font-size for the datepicker control directly. Obvious once you know about it, but confusing at first.


I can't add a comment, so this is in reference to the accepted answer by Keijro. I actually added the following to my stylesheet instead:

    div.ui-datepicker {
    font-size: 62.5%;
}

and it worked as well. This might be preferable to the absolute value of 10px.


Another approach:

$('.your-container').datepicker({
    beforeShow: function(input, datepickerInstance) {
        datepickerInstance.dpDiv.css('font-size', '11px');
    }
});

This code will work on Calender buttons. size of numbers will increase by using "line-height".

/* Change Size */
<style>
    .ui-datepicker{
        font-size:16px;
        line-height: 1.3;
    }
</style>

I was trying these examples without success. Apparently other stylesheets on the page were setting default font sizes for different tags. If you adjust the ui-datepicker you are changing a div. If you change a div you need to make sure the contents of that div inherit that size. This is what finally worked for me:

<style type="text/css">
.ui-datepicker-calendar tr, .ui-datepicker-calendar td, .ui-datepicker-calendar td a, .ui-datepicker-calendar th{font-size:inherit;}
div.ui-datepicker{font-size:16px;width:inherit;height:inherit;}
.ui-datepicker-title span{font-size:16px;}
</style>

Good luck!


The Jacob Tsui solution works perfect for me:

$('#event_date').datepicker({
    showButtonPanel: true,
    dateFormat: "mm/dd/yy",
    beforeShow: function(){ 
        $(".ui-datepicker").css('font-size', 12)
    }
});

We can alter in the default 'jquery-ui.css' file as below given code:

div.ui-datepicker {
font-size: 80%; 
}

However, changing the default 'jquery-ui.css' file is not recommended as it might have been used somewhere else in the project. Changing values in the default file can alter datepicker font in other webpages where it has been used.

I used the below code to alter "font-size". I placed it just after datepicker() is called as shown below.

<script>
        $(function () {
            $( "#datepicker" ).datepicker();
            $("div.ui-datepicker").css("font-size", "80%")
        });
</script>

Hope this helps...


For me, this was the easiest solution: I added the font-size:62.5%; to the first .ui-datepicker tag in the jquery custom css file:

before:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none;} 

after:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none; font-size:62.5%; }

I tried the approach of using the callback function beforeShow but found I had to also set the line height. My version looked like:

beforeShow: function(){$j('.ui-datepicker').css({'font-size': 11, 'line-height': 1.2})}
