Fixing "Read More" link to be accessible to screen readers

Just a reminder for myself, to make links accessible to screenreaders, use the following template or a variation of thereof:
    <a href="..."
      <span data-bind="text: regularLinkText">
      <span data-bind="text: accessibleLinkText" class="sr-only"> <!-- this will be the text for screen reader and not visible to naked eye -->
The problem I kept having was that I set the data-bind="text: linkTextHere" on the actual <a> tag, and that wiped out whatever other controls I nested inside.

Skip a link while tabbing over a web page or access a link via tab

One way of doing it is to remove the href element of the link.

In contrast, if a link cannot be reached to while tabbing over a page, adding an

would make the link reachable via tabbing. Moreover, if a 'click' event is attached to the link, the element will respond to the Enter key press despite the fact that the 'keyup' (or other key type event) is not attached.

Timer to count up in JavaScript

Here is my implementation, nothing original or extraordinary. Putting it here for future reference.
        var totalSeconds = 0;
        var timer;

        function startTimer() {
            timer = setInterval(function () {
                var t = document.getElementById("time2"); //or other place where to display data
                t.innerHTML = displayTimer(totalSeconds);
            }, 1000); 

        function stopTimer() {

        function displayTimer(numberOfSeconds) {
            var result = "";

            var hours = Math.floor(numberOfSeconds / 3600);
            if (hours > 0) { result += hours + " h "; }

            var minutes = Math.floor((numberOfSeconds - (hours * 3600)) / 60);
            if (minutes > 0) { result += minutes + " m "; }

            result += (numberOfSeconds % 60 + " s");

            return result;

To remember: declaring an inline array for splitting strings

This is how to declare an inline char array (C#) to split the string into multiple parts:

List result = inputLine.Split(new[] {'%'}, StringSplitOptions.RemoveEmptyEntries).ToList();
