Dropzone fixed height with horizontal scroll

I'm not adept enough in advanced CSS or dropzone to know how to modify the template so any help is appreciated. I would like to create a fixed-width, single-row-height area for the dropzone thumbnails that scrolls left-to-right for showing any files currently in the dropzone uploader.
Any help is appreciated. FYI, I have already isolated the CSS styles that set the width: 50% and I'm assuming at least part of the work goes there.

OK, with some banging on the keys like one of those infinite monkeys, I was able to figure it out:
first I added an additional class name to my dropzone container:
<div class="dropzone hzScroll" id="lpDropzone"></div>
Then I added a style definition above it:
<style>
.dropzone .dz-preview.lp-preview {
width: 150px;
}
.dropzone.hzScroll {
width: 740px;
overflow: auto;
white-space: nowrap;
}
</style>

Bootstrap Header Logo Image Not Showing in Mozilla

Bare in mind I'm fairly novice with HTML and CSS. I've got a logo in my bootstrap header on my website (www.prettyugly.co.nz)
I originally used the follow code to display it and it worked fine in Chrome
.image {
content: url("/img/logo-white.png");
}
then this in the HTML to call that CSS
<div class="image"></div>
I since learned that you have to use the :before command for content to work in Firefox, however I can't get it to work across the board.
Any ideas?

You should simply show the image using (HTML):
<div><img src="/img/logo-white.png" /></div>
But if you want to set it as background, then you should use (CSS):
.image {
background-image: url("/img/logo-white.png");
width: 225px; height: 63px; /* Dimensions of image */
}

TinyMCE color picker dropdown appears off-screen

This is an issue on Firefox and IE so far that I've tested; the problem does not exist on Chrome.
I'm including two TinyMCE editors on a page with one partially off-screen to start. When I select the color picker dropdown option from the toolbar on the first TinyMCE instance, the dropdown appears where it should. But if I scroll down and select the color picker dropdown in the second instance, that dropdown appears way below the editor and typically off the page.
You can see this in action here: http://jsfiddle.net/nm6wtca3/
Without removing the html, body CSS, what can I do to have the color picker always appear in the correct position?
I've traced the problem down to setting CSS on the html, body elements.
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}
The dropdown div has CSS applied to it that is auto-calculated by TinyMCE. It looks something like this:
z-index: 65535;
left: 641.467px;
top: 633px;
width: 162px;
height: 105px;
How it appears in FF (sometimes way worse):
How it appears in Chrome (how it should look):

You did say you don't want to remove any CSS from the html,body, but you didn't say anything about adding to it! This solution is based on the assumption that you can add to the html,body
Solution
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
position: relative; /* Line added */
}
JSFiddle Example
I hope this helps. In all reality, you really only need to apply position: relative; to the body like so body { position: relative; }

I'm not super familiar with tinymce's colorpicker, but I can see the issue, and I can replicate it reliably: your problem occurs when you have a picker open, and then you scroll. I can replicate this in chrome too. Here's a video.
When I look at the DOM, I see that tinyMCE has created two absolute-positioned divs at the end of document.body, one for each picker. When you open one, their position is updated to reflect the location of the toolbar-button at the time you clicked it, but it never gets updated when you scroll!
So, how to solve this? Well, there are a few possibilities:
Option 1: it looks like tinyMCE provides a method to bind a control to an event (here). With this, you could bind a callback to 'scroll' that repositions the box...
Huh, now that I think of it, you could simply close any open colorpickers whenever a user scrolls ... kinda feels like a cop-out but there's no denying it has the best R.O.I. ;) We'll call that Option 2!
Option 3: depending on the implementation of the colorpicker, you may be able to override where in the DOM those divs get rendered. The API method I saw that looked the most promising is here. Once you have the div inside a relative-positioned parent, you'd also have to make the colorpicker's positioning algorithm smart enough to look in the right place for x and y offset ...when I tried this by just moving the element and mashing in some css by hand in chrome-console, the algorithm still computed x and y offsets based on doc.body, so depending on where you were scrolled at click-time, everything would be out of position
It looks like this issue might be troubling other people as well... maybe they've found a solution but haven't posted anything about it?
I hope this is enough info to get you past the problem... Let me know if you have any questions!

It looks like the problem is caused by overflow-x: hidden;
It may not be the answer you want but removing that or moving it to a page wrapper will solve your problem.
Working Example
html, body {
width: 100%;
height: 100%;
padding:0;
margin:0;
}
#pagewrapper{
overflow-x: hidden;
}
Another option would be to force repositioning on scroll, but honestly this is overkill... I strongly recommend fixing the css instead.
Another working example
$('body').scroll(posfix); // when the body scrolls
$('#mceu_10').click(posfix); // when you click the top font color button
$('#mceu_35').click(posfix); // when you click the bottom font color button
function posfix() {
setTimeout(function () { // hack way to ensure it fires after the menu is shown
$('#mceu_51').css({
top: $('#mceu_10').offset().top + $('#mceu_10').height(), // set top/left based on button's position
left: $('#mceu_10').offset().left + $('#mceu_10').width() / 2
});
$('#mceu_52').css({
top: $('#mceu_35').offset().top + $('#mceu_35').height(),
left: $('#mceu_35').offset().left + $('#mceu_35').width() / 2
});
}, 1);
}

it works on firefox, and Internet Explorer fine
just remove this css code
html, body {
width: 100%;
height: 100%;
overflow-x: hidden;
}

Please take a look at this:
html,
body {
width: auto;
height: auto;
overflow-x: hidden;
}
You can simply set body width and height to auto, then there won't be any need to use position and you don't have to remove anything. I think you do not need to use height: 100% since it will be auto-calculated by TinyMCE. i hope it helped.
Update
Look at the screen shot from chrome and its same in firefox. And i didn't remove any css but just changed..and by putting 100% in css the output will be like :-
Please check this one with auto but not 100%..thank you

Srcolling to a div with jQuery

My site has blog posts played out down the page… In the top right, I have navigation, with an option to jump to the last post in September. I know the id of the div that contains this post is #post2, so I'm trying to use jQuery to scroll the page to that div, like this:
$("html, body").animate(
{ scrollTop: $("#post2").offset().top },
500);
What could I be doing wrong?

You can utilize the window.scrollTo function, by calculating the according coordinates, but if you are using jQuery there are out-of-the-box ready plugins with smooth scrolling support like jquery.scrollTo.
Here a Code-Snippet that demonstrates it:
$(function(){
$('#btn').click(function(){
$.scrollTo('#post2', 800 );
});
});
div {
width: 200px;
}
#large {
height: 1500px;
background-color: grey;
}
#post2 {
height: 100px;
background-color: blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://demos.flesler.com/jquery/scrollTo/js/jquery.scrollTo-min.js?1.4.11"></script>
<button id="btn">scroll</button>
<div id="large"></div>
<div id="post2"></div>
In your case you need to add overflow: hidden; to the UIPostContainer class, since you can not scroll to an element without a height. And because you have a ~50px height fixed header that overlays everything you have to account for that as well, e.g. like that: $.scrollTo("#post2 h4", 800, {offset: {top:-55} });

Your code is 100% right it has no mistake
and as I saw your site is working too

Your code is right but the behavior you want is not there because the height for the divs of postcontainer like $('#post2) is not correct (it is 0px) in terms of styling.

Google Maps zoom control is messed up

I use the Google Maps API (v.3) to show a map with a couple of markers. I recently noticed that the control used to zoom the map is messed up (it wasn't always like this). I have no idea what the cause is.
Update
This post originally had a link to a page where you could view the issue, but the link is broken now, so I've removed it.

Your CSS messed it up. Remove max-width: 100%; in line 814 and zoom controls will look fine again. To avoid such bugs use more specific selectors in your CSS.

#myMap_canvas img {
max-width: none;
}
fixed it for me, but I also wanted to point out the comment on the question by #Ben, "This issue doesn't happen with Bootstrap if you use the is map_canvas as the map div id". He's right. I'm not using Bootstrap, but the problem started happening after I changed the div id.
Setting it back to map_canvas fixed it without the max-width change.
<div id="map_canvas"></div>

If you're using Bootstrap, just give it "google-maps" class. This worked for me.
As an alternative you might reset everything for the google map div as a kind of last-resort solution:
HTML:
<div class="mappins-map"><div>
CSS:
.mappins-map img {
max-width: none !important;
height: auto !important;
background: none !important;
border: 0 !important;
margin: 0 !important;
padding: 0 !important;
}

Just share #Max-Favilli answer:
With latest version of google maps api you need this:
<style>
.gm-style img { max-width: none; }
.gm-style label { width: auto; display: inline; }
</style>
Thanks to #Max-Favilli

If you're a Twitter Bootstrap user you should add this line to your CSS:
.gmnoprint img { max-width: none; }

I had this problem as well and using
.google-maps img {
max-width: none;
}
didn't work. I eventually used
.google-maps img {
max-width: none !important;
}
and it worked like a charm.

If you're using Yahoo's Pure CSS, give your div the "google-maps" class like Bootstrap, and put this rule in your CSS:
.google-maps img {
max-width: none;
max-height: none;
}
As far as I can tell, Pure CSS has no way of fixing this issue on its own.

Those options you guys told me didn´t work for my website.
I use Bootstrap V3 and focussed on the functionality. The main reason was that i had given my map a different ID then the CSS file used to display the zoom bar with the yellow streetvieuw guy
I renamed map_canvas to mapholder and then it worked for me! Thanks anyways for the hints that i should look into the CSS files!

I tried all the above solutions, and others from other forums to no avail. it was really annoying because I have another non-Wordpress site where the code worked perfectly. (I was trying to display a Google map in a Wordpress page, but the zoom and Streetview controls were distorted).
The solution I did was to create a new html file (copy paste all the code into Notepad and name it xyz.html, save as type "all files"). Then upload/ftp it up to website, and setup a new Wordpress page and use an embed function. When editing the page go to the text editor (not the visual editor) and copy/type:
http://page URL width="900" height="950">
If you change the dimensions, remember to change it in both arguments above, or you get weird results.
There we go - might not be as clever as some other answers, but it worked for me! Evidence here: http://a-bc.co.uk/latitude-longitude-finder/
