Removing dotted bottom border from CSS tool tip's title text

I would like to remove the dotted bottom border from the text linked to the tool tip. This code is being used within Qualtrics to modify a survey for a client. Would it be best to edit the text decoration in this case? I need it to be stable across browsers. Admittedly I am not trained in coding - just self taught, so please provide context to your answers so that I can either look up more information regarding your directions or parse it together with what I already know.

<abbr rel="tooltip" title="The curricula available for teacher use provides guidance for how to differentiate lessons, activities, and assessments; includes the principles of Universal Design for Learning; and teachers are trained in implementation of the curriculum.">General education teachers have access to a curriculum that promotes differentiated instruction for all students. </abbr>

Text decoration seems like the way to go either by targeting the tag or by adding a class and targeting that:
abbr {
text-decoration: none;
}
Might consider the accessibility considerations too while you're implementing this. It's usually a good idea to give users an indication of some kind when something is interactive. I wonder if removing the underline will remove any indication that there is a tooltip available?

jQuery prev/next button in polaroid gallery plugin

I am using a polaroid image gallery plugin. The way it works, the polaroid images are scattered in a div and it has some circle nav buttons at the bottom that can be clicked to make the selected image active and moves it to the middle.
Instead of having circle nav buttons for selecting each image, I wanted to use prev/next buttons (this way it won't show 20+ circle nav icons when the gallery has more than 20 photos).
I was able to add some prev/next buttons and get them working, but there is one slight issue I cannot figure out. When the gallery loads, if you select the prev/next buttons, the gallery works as intended, it will switch the photos as necessary when the buttons are clicked. However, if the user clicks anywhere in the gallery (not on the buttons) it will shuffle all of the photos (it should not shuffle), then once a user does this, the prev/next buttons no longer work until the page is refreshed.
I am still learning jQuery/js and I cannot figure out what is causing this. I need to restrict the shuffling and selecting of the photos only when the prev/next buttons are selected because if a user accidentally clicks anywhere in the gallery, the buttons break.
I created a jsfiddle here.
The html is pretty straight forward, here is an example with the prev/next buttons I added:

The custom jQuery used to add the prev/next buttons and remove the circle nav icons is:
var ps = new Photostack( document.getElementById( 'photostack-1' ), {});
$("#leftArrowGallery").prependTo($(".photostack > nav"));
$("#rightArrowGallery").appendTo($(".photostack > nav"));
$("#leftArrowGallery").on("click", function () {
ps.navigate('prev');
});
$("#rightArrowGallery").on("click", function () {
ps.navigate('next');
});
$(".photostack > nav > span").each(function(){ $(this).remove(); });
You can view all of the js for the plugin in the jsfiddle.

Again, the buttons are working correctly, I just need to prevent when someone clicks anywhere in the gallery, it shuffles the images then the prev/next buttons break and no longer work until the page is refreshed.
Thank you for your help!

I read your code and I found out that the biggest problem when you put photostack-start class is that every time you click on photostack stage you schuffle your photos twice: once in _photoShow function and once in open function (open function is triggered every time). To resolve your problem, a solution could be to stop one schuffled action. To do this I created a variable and I put it in open function:
if( this.open ) {
return false;
}
this.open = true;
Now, _open function is triggered only once (when you click on button "view gallery") and after that only _photoShow works so your code works finally as you want.
BE CAREFUL: In this example I removed some pics 'cause I have a character limit here (30000), but the code will work anyway also with more pics.
A fiddle with more pics: https://jsfiddle.net/m46cxkhg/217/ (tested with Chrome and Firefox)

Generate Excel file thumbnail preview in Javascript

I have a project handling a library of excel files. To make it easilier for the users to visually scan them, I would like to generate preview thumbnail images of their content. Google drive does this (screenshot below) but I have no idea how.
Any ideas/suggestions on how this could be done (without using the drive API) ?

I guess this is what you need

Those previews were fetched as soon as this page loaded. This is great for having the previews ready ahead of time, but can eat up extra bandwidth. As an alternative, check out these links to Abduzeedo and Smashing Magazine. These previews aren't fetched until you hover over this paragraph.

Finally, check out these links to Daniel's blog, Joni's blog, and my blog. These previews are only fetched when needed. This saves the most bandwidth, but there will be a delay before the previews can be shown.

I just use a library to generate a PNG preview of the excel file and show it.
I use Free Spire.XLS for .NET because I'm in the .net world, but you can look at Wijmo Workbook Viewer for your Node.js needs.

Thumbnail grid with expanding preview navigation

I have implemented the grid into a site and it's all working great! I have added a previous and next button using the JavaScript file to append them but can't seem to get them to cycle previous and next.
I notice Google's image search you can use the arrow keys to cycle through them but would like to use these buttons to do it. I know you can target the name attribute and cycle through the images but in this particular grid there is only the data-largesrc which I can't seem to target (I can target the img src of the thumbs. The images are in <li> so maybe that could be targeted? Any ideas would be appreciated. The JavaScript file is a bit big...

do you can see the script (view code) in the demo http://jqueryui.com/demos/slider/#side-scroll ?
just make litle modification to the scripts, just change to:
$(function() {
var scrollPane = $( ".scroll-pane" ),
scrollContent = $( ".scroll-content" );
var scrollbar = $( ".scroll-bar" ).slider({
value:100,
min: 0,
max: 500,
step: 50,
slide: function( event, ui ) {
if ( scrollContent.width() > scrollPane.width() ) {
scrollContent.css( "margin-left", Math.round(
ui.value / 100 * ( scrollPane.width() - scrollContent.width() )
) + "px" );
} else {
scrollContent.css( "margin-left", 0 );
}
}
});
});
i have tried and it's works. then just make finishing touch for your need
