this shows using setTimeout to animate the images.
when i press "KEY_RIGHT" : the images stopped and shows next animated image.
but problem is images overlaps with stopped images and the next images.
how do i remove all the stopped or previous images(FOCUS_AA) when key pressed next step(FOCUS_AB)?

If you were to animate via jQuery, you could call .stop() on all animations and have the always action on animations would be to hide the photos. That way, even if you were in the middle of an animation, the animation would stop, go immediately to the end and the next animation would go.

Avoid repeating myself

I'm sure there is a way to write a shorter version of the following js code. In the end I'm just repeating myself over and over again. Any suggestions?
Thanks a lot!
if (designVal == 0 && colorVal == 0) {
design01yellow.style.display = "block";
design01black.style.display = "none";
design01blue.style.display = "none";
design01grey.style.display = "none";
design02yellow.style.display = "none";
design02black.style.display = "none";
design02blue.style.display = "none";
design02grey.style.display = "none";
design03yellow.style.display = "none";
design03black.style.display = "none";
design03blue.style.display = "none";
design03grey.style.display = "none";
} else if (designVal == 0 && colorVal == 1) {
design01yellow.style.display = "none";
design01black.style.display = "block";
design01blue.style.display = "none";
design01grey.style.display = "none";
design02yellow.style.display = "none";
design02black.style.display = "none";
design02blue.style.display = "none";

design03black.style.display = "none";
design03blue.style.display = "none";

} else if (designVal == 0 && colorVal == 2) {
design01yellow.style.display = "none";
design01black.style.display = "none";
design01blue.style.display = "block";
design01grey.style.display = "none";
design02yellow.style.display = "none";

design02grey.style.display = "none";
design03yellow.style.display = "none";
design03black.style.display = "none";
design03blue.style.display = "none";
design03grey.style.display = "none";
} else if
///AND SO ON

Give all the elements a common class (e.g. class="design"). Loop over them, setting them all to none, then set the specific element to block.
document.querySelectorAll(".design").forEach(el => el.style.display = "none");
if (designVal == 0 && colorVal == 0) {
design01yellow.style.display = "block";
} else if (designVal == 0 && colorVal == 1) {
design01black.style.display = "block";
} ...

I'd normalize them to 'display: none' and then only set the one you want to display: block.
if (designVal === 0) {
design01yellow.style.display = "none";
design01black.style.display = "none";
design01blue.style.display = "none";
design01grey.style.display = "none";
design02yellow.style.display = "none";
design02black.style.display = "none";
design02blue.style.display = "none";
design02grey.style.display = "none";
design03yellow.style.display = "none";
design03black.style.display = "none";
design03blue.style.display = "none";
design03grey.style.display = "none";
if(colorVal === 0) {
design01yellow.style.display = "block";
} else if (colorVal === 1) {
design01black.style.display = "block";
} else if (colorVal === 2) {
design01blue.style.display = "block";
}
// and so on

Cannot read property 'style' of null in three places

When I run my code it give me this error: TypeError: Cannot read property 'style' of null at onlyShowInput1H (/:673:42) at showInputH (/:995:9) at HTMLButtonElement.onclick (/:85:117
In more detail here is what code does:
user inputs 1-10 tasks in the 1st div user inputs 1-10 tasks in the 2nd div (stored in localStorage)
user inputs 1-10 tasks in the 3nd div(stored in localStorage)
A do list is displayed with all the inputs the user inputed(stored in localStorage)
This error is being displayed: TypeError: Cannot read property 'addEventListener' of undefined at /script.js:66:5 TypeError: Cannot read property 'style' of null at onlyShowInput1H (/ITHB.js:457:42) at showInputH (/ITHB.js:779:9) at HTMLButtonElement.onclick (/:85:104)
I think the second error is affecting my code, from saving the 21st input because it's not reading it
Here is a link to a plunker of my code: https://plnkr.co/edit/HbT4WKFpqQrW5Ikv?open=lib%2Fscript.js
And here is a code snippet (not of my entire code but the part that isn't working):

Javascript: How can this code be reduced or improved?

This is some JS that I've written, how can this be reduced?
it swaps the text as in hides one div and displays the other.
var directorOne = document.getElementById('directorOne').addEventListener("click", changeText);
var directorOneText = document.getElementById('directorOneText');
function changeText() {
if (directorOneText.style.display === "block") {
directorOneText.style.display = "none";
directorTwoText.style.display = "none";
console.log("luke open");
} else {
directorOneText.style.display = "block";
directorTwoText.style.display = "none";
}
}
var directorTwo = document.getElementById('directorTwo').addEventListener("click", changeText2);
var directorTwoText = document.getElementById('directorTwoText');
function changeText2() {
if (directorTwoText.style.display === "block") {
directorTwoText.style.display = "none";
directorOneText.style.display = "none";
console.log("bruce open");
} else {
directorTwoText.style.display = "block";
directorOneText.style.display = "none";
}
}

Using a single function that is called with the elements as parameters
var directorOneText = document.getElementById('directorOneText');
var directorTwoText = document.getElementById('directorTwoText');
function changeText(t1, t2) {
t1.style.display = (t1.style.display === "block") ? "none" : "block";
t2.style.display = "none";
}
var directorOneClickEvent = document.getElementById('directorOne').addEventListener("click", function(){ changeText(directorOneText, directorTwoText)});
var directorTwoClickEvent = document.getElementById('directorTwo').addEventListener("click", function(){ changeText(directorTwoText, directorOneText)});
#directorOne {background:#333; padding: 20px;}
#directorTwo {background:#ddd; padding: 20px;}
<div id="directorOne">d1<textarea id="directorOneText"></textarea></div>
<div id="directorTwo">d2<textarea id="directorTwoText"></textarea></div>
