Developing with AngularJS - Part IV: Making it Pop

Welcome to the final article in a series on my experience developing with AngularJS. I learned its concepts, beat my head against-the-wall with and finally tamed it enough to create a "My Dashboard" feature for a client. For previous articles, please see the following:

The last mile of development for the My Dashboard feature was to spice things up a bit and make it look better. We hired a design company to come up a new look and feel and they went to work. Within a week, we had a meeting with them and they presented a few different options. We picked the one we liked the best and went to work. Below are screenshots that I used to implement the new design.

My Dashboard - New Design My Dashboard with Show More

At first, I thought implementing this design might take quite a bit of effort, since it looked like it used custom fonts. It's true we could use CSS3's @font-face, but I knew it might take awhile to find the right fonts with the appropriate licenses. When I received the screenshot below, I was pleased to see that all fonts were web-safe.

My Dashboard Fonts

Design Elements

There are a number of elements in this new design that I had to create. For example, if numbers were only 1 digit, we had to add a leading zero to them in the summary band. Other design elements we needed to implement are listed below:

  • A background image that filled the page
  • Fade to white on summary widget titles
  • A responsive grid for summary widgets
  • Provide a colored background for odd rows in the summary grid
  • Add a "Show More" band at the bottom of Tasks, Summary and Reports when there's more items to display

New Background

The new background shown in the screenshots above has a light source in the middle of it. Therefore, it's impossible to tile/repeat it across the page since it's not uniform. To make it work, I used a 1024 x 768 image and CSS3's background-size: cover. For more information on background-size, see SitePoint's How to Resize Background Images with CSS3. This worked great on smaller screens, but we noticed some issues on 30" monitors. Therefore, we ended up getting a new repeatable background and stopped using background-size.

LeadingZero filter

For the first leading zero feature, I wrote an Angular filter. I put the code for this in filters.js:

filter('leadingZero', function() {
    return function(input) {
        if (input.length === 1) {
            return "0" + input;
        } else if (input.length > 2) {
            return "+99";
        } else {
            return input;

This filter is used in the HTML template as follows:

<div class="summary-value">{{widget.value | leadingZero}}</div>

Text Fade Out

To implement the fade-to-white text in summary titles, I started with this tutorial. I quickly discovered that it worked best for vertical text blocks and not for horizontal text. Then I found Text Ellipsis with Gradient Fade in Pure CSS, which uses :after to position a block over the text that fades to white. Since the title is not the right-most element (the numbers are), I had to figure out best positioning that worked cross-browser. Below is the CSS I used to implement this feature.

.dashboard .summary-title:after {
    display: block;
    position: absolute;
    right: 66px;
    top: 5px;
    bottom: 5px;
    width: 30px;
    background: -moz-linear-gradient(left,  rgba(255,255,255,0) 0%, #fff 20px); /* FF3.6+ */
    background: -webkit-linear-gradient(left,  rgba(255,255,255,0) 0%, #fff 20px); /* Chrome10+,Safari5.1+ */
    background: -o-linear-gradient(left,  rgba(255,255,255,0) 0%, #fff 20px); /* Opera 11.10+ */
    background: -ms-linear-gradient(left,  rgba(255,255,255,0) 0%, #fff 20px); /* IE10+ */
    background: linear-gradient(to right,  rgba(255,255,255,0) 0%, #fff 20px); /* W3C */
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00ffffff', endColorstr='#ffffff',GradientType=1 ); /* IE6-9 */
    content: "";

Responsive Grid

To implement the responsive grid of summary widgets, I started with Codrops' Responsive Full Width Grid Tutorial. This proved to be a great model and I used the following CSS to position all the <li>'s appropriately. In the code below, .summary-item is the class on the <li> elements.

.dashboard .summary-item {
    border-right: 1px solid #d1d1d1;
    border-bottom: 1px solid #d1d1d1;
    /* put the border on the inside of the box */
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    -ms-box-sizing: border-box;
    box-sizing: border-box;
    font-family: Constantia, "Lucida Bright", Lucidabright, "Lucida Serif", Lucida, "DejaVu Serif", "Bitstream Vera Serif", "Liberation Serif", Georgia, serif;
    font-size: 14px;
    color: #666;
    height: 50px;
    box-shadow: inset 0 0 6px rgba(0,0,0, 0.25);
    /* responsive grid */
    position: relative;
    float: left;
    overflow: hidden;
    width: 25% /* Fallback */
    width: -webkit-calc(100% / 4);
    width: calc(100% / 4);

@media screen and (max-width: 1400px) {
    .dashboard .summary-item {
        width: 33.33333333333333%; /* Fallback */
        width: -webkit-calc(100% / 3);
        width: calc(100% / 3);

@media screen and (max-width: 1000px) {
    .dashboard .summary-item {
        width: 50%; /* Fallback */
        width: -webkit-calc(100% / 2);
        width: calc(100% / 2);

This worked great in most browsers, but we did find an issue with IE9. When squishing/expanding the browser window, sometimes there would be a blank column on the right side. To fix this, I changed the width on the default .summary-item to be 25%, and removed the lines with calc.

.dashboard .summary-item {
    width: 25%

Coloring Odd Rows

Coloring odd rows in a table is easy, but when the rows are in a responsive grid, that's a whole different story. For tables, the CSS rules are extremely simple:

tr:nth-child(even) {background: #CCC}
tr:nth-child(odd) {background: #FFF}

Via Twitter, @tomaslin advised me that the nth-child selector could probably be used for this, but it'd likely require some JavaScript to make it responsive. I found the excellent Master of the :nth-child and began trying to figure it out. The following function is what we now use to color odd rows in the Summary Bar.

function colorRows() {
    var lisInRow = 0;
    var items = $('.summary-items li');
    items.each(function() {
        if($(this).prev().length > 0) {
            if($(this).position().top != $(this).prev().position().top) return false;
        else {
    var rows = items.length / lisInRow;
    for (var i = 0; i < rows; i++) {
        var selector = "nth-child(n+{x}):nth-child(-n+{y})";
        var x = (lisInRow * i) + 1;
        var y = x + (lisInRow - 1);
        selector = selector.replace('{x}', '' + x);
        selector = selector.replace('{y}', '' + y);
        if (i % 2) {
            $('.summary-items li:' + selector).addClass('odd');
        } else {
            $('.summary-items li:' + selector).removeClass('odd');

The above code is in dashboard.js and is called anytime the browser window is resized (to adapt to the responsive grid).


It's also called when summary widgets are re-ordered, in the updateOrder() function of WidgetController.

$scope.updateOrder = function(event, ui) {
    Preferences.saveWidgetOrder(type, {items: items});
    if (type === 'summary') {

I'd like to figure out how to make this more Angular-esque, but all the "how to hook into window.resize" articles I found make it seem harder than this.

Show More

The last feature I had to implement was the "Show More" bar that appears when widgets are hidden. This was the most difficult thing to implement and I tried many different things before arriving at a solution that works. First of all, the widgets bars that can be expanded are put into their original (collapsed) state using max-height and overflow: hidden. From there, I look at the list inside the bar and compare the height's of the two elements. If the list is taller than the bar, the Show More bar is added.

I originally looked at the list's :last-child to see if it was visible, but jQuery's :hidden selector only works on items that are hidden by display: none rather than ones that are hidden by overflow.

As you can see from the code below, there's special logic needed to expand the min-height of the Summary Bar since it doesn't have enough room at the bottom to add the bar in its collapsed state.

function showMore(element) {
    var bar = element.parent().parent();
    var list = element.parent();
    var barId = bar.attr('id');
    var listHeight = list.height();
    var barHeight = bar.height();
    var isSummaryBar = (barId.indexOf('summary') > -1);
    var summaryBarMinHeight = 260;
    var showMoreShouldBeVisible = (isSummaryBar && element.position().top >= 200) ? true : listHeight > barHeight;
    if (showMoreShouldBeVisible) {
        var messages = {};
        // the variables below are defined in the host page, before this file is loaded
        messages.more = showMoreText;
        messages.less = showLessText;

        var showMore = $('<div class="show-more"/>').html(messages.more + " <b class='caret'></b>");
        // summary bar doesn't have enough room for the Show More bar in its collapsed state,
        // so change it from 242 to 260
        if (isSummaryBar) {
            bar.css({'min-height': summaryBarMinHeight + 'px', 'max-height': ''});

        showMore.bind('click', function (e) {
            var element = $(this);
            var parent = element.parent();

            if (element.hasClass('less')) {
                parent.css({"max-height": ''});
                if (isSummaryBar) {
                    parent.css({"min-height": summaryBarMinHeight + 'px'}).animate(200);
                } else {
                    parent.css({"min-height": ''}).animate(200);
                element.html(messages.more + ' <b class="caret"></b>');
            } else {
                    "max-height": 9999,
                    "min-height": 'auto'
                        "min-height": parent.height() + 19
                    }, 200);

                element.html(messages.less + ' <b class="caret caret-up"></b>');

            // prevent jump-down
            return false;
    } else {
        // Remove show-more in case it was previously added
        if (bar.find('.show-more').length > 0) {
            if (isSummaryBar) {
                bar.css('min-height', summaryBarMinHeight - 18)
            } else {
                bar.attr('style', '');


function showMoreOnResize() {
    var dataItems = $('.task-items,.summary-items,.report-items');
    dataItems.each(function() {
        var lastItem = $(this).find('li:last-child');
        if (lastItem.length > 0) {

At first, I wrote this logic as a directive, but when I needed it for responsiveness, I moved it into dashboard.js. The showMoreOnResize() function is called on window resize.


I also found that I had to add it to the Preferences service after widgets were saved (since the number displayed could change).

factory('Preferences', function ($filter) {
    return {
        // Save hidden and visible (and order) widgets from config dialog
        saveWidgetPreferences: function (type, widgets) {
            DWRFacade.saveDashboardWidgetPreference(type, preferences, {
                callback: function() {
                    // recalculate show more bar
                errorHandler: function (errorString) {

To implement the .caret-up (the .caret class is from Bootstrap), I found a caret-right howto and used it to create .caret-up:

.caret-up {
    border-left: 4px solid transparent;
    border-right: 4px solid transparent;
    border-top: 4px solid transparent;
    border-bottom: 4px solid black;


The final My Dashboard feature is something that I'm quite proud of. A fellow developer, Vlad, did an excellent job of implementing the backend and admin portions. The Product Team's vision and desire to make it Pop! created something great. The fact that we didn't have to support IE8 helped a lot in the implementation. Below is a screenshot of how My Dashboard looked when we completed the project.

My Dashboard

Angular isn't mentioned much in this article. That's because we didn't have to do much to the existing Angular code to implement the new design. It was just a matter of writing/modifying some CSS as well as introducing some JavaScript for colored rows and show more. If you know how these features could be written in a more Angular Way, I'd love to hear about it.

Right now I'm pretty envious of your "we got a designer in". I'm hoping at some point soon we can do the same with our AngularJS/Bootstrap/Clojure app.

What I like very much about AngularJS is that, much like Tapestry, a lot of critical behaviors filter through a couple of services that can be augmented in various ways.

For example; I have a directive that can be placed on an ngForm that prevents navigation away from a *dirty* form without a confirmation (and the confirmation is a Bootstrap Modal dialog). Likewise, submit buttons are disabled until the form is valid. All very neat and clean. That's nice and would be hard to do using bespoke jQuery. There's just a lot of room for finesse, which I really appreciate.

Hai, Can you send the project to my mail id.

Posted by Azhagasamy on December 23, 2015 at 12:04 AM MST #

Azhagasamy: I no longer have the source code for this project. Even if I did, I wrote it for a client and I wouldn't be allowed to share it without their permission.

Thank you for your reply. if you have any demo project send to me.

Posted by Azhagasamy on December 29, 2015 at 08:43 PM MST #

Awaiting for your reply.

Posted by Azhagasamy on December 30, 2015 at 02:13 AM MST #

I do not have a demo project to send you. Your best bet is to try and implement it yourself.
