How do I remove the small blank/uncovered space at the bottom of my blogger blog?

I have a blogger blog, and I need to know how to have the footer entirely cover the bottom of the page. When you scroll to the bottom, there is a small gap between the content container which is obviously black, and the bottom of the browser window. How do I fix this? How do I make the content container stretch to the bottom of the page entirely?

You can use
.content{
heigth : 100%;
padding : 5px;
margin : 5px;
}

Changing CSS for .content-inner to this will work although there might be a better solution available, so keep looking at answers in this thread.
.content-inner {
margin-top: -20px !important;
min-height: 100vh;
}

I experimented with the answer Dr. Geek gave me, and had a problem with a horizontal scrollbar appearing at the bottom and throwing the pages setup off from the main setup, so I added this to the custom CSS for now:
.content{
margin-bottom: -1px;
}
It's a very simple fix, and anyone who uses blogger and wants to remove a gap from the bottom of their blog will have this answer hopefully.

scaleY property not maintained properly for small screens

I am tryng to fix a css bug for mobile screens
when I click section 1 content opens and if i move till the bottom of the section one content and after that if I click section 1 content closes.
but I dont see section 2 after that I see section 3 since the screen moves upwards.
how to retain the section 2 in our screen.
am I doing anything wrong with the scaleY property.
providing the related code below
I used scrollIntoView but still not point to second one any idea???
I used window.scrollTo(0, 0) but still not point to second one any idea???
.television .chromecast .sun .sunItem > .bulb {
overflow: hidden;
transition: transform .5s, max-height .5s;
transform: scaleY(0);
box-sizing: border-box;
max-height: 0;
transform-origin: center top;
}
.television .chromecast .sun .sunItem.selected > .bulb {
transform: scaleY(1);
max-height: 100%;
}

We need to invoke properly on the select function
onSelect() {
this.props.onSelect(this.props.id);
this.focusDiv();
}

That's the expected behaviour. The scroll position is retained but you remove content from the top of the screen so you end up further down in the page.
It's always a bad idea to collapse the previous elements when expanding a new one, especially on mobile.
To fix that, you will need to script a scrolling to the top of the open section. That could easily be achieved using jQuery.ScrollTo() or something similar, but to be honest, I would just leave the previous sections open, unless the users have a tendency to scroll back up and that would require to much scrolling to get back to the top of the page. Other UX solutions like a scroll to top link might come in handy to solve that.

CSS/Javascript Auto Scroll To Top

I am currently working on a simple (or so I thought) slide-down menu for both the desktop and mobile versions of a website I am working on. I'm trying to do this in CSS only if possible. Currently the CSS I am using is as follows:
#menu {position: absolute; top: 0; left: 0; width: 100%; max-height: 50px; overflow: hidden; -webkit-transition: all 1s ease; /* For Safari 3.1 to 6.0 */ transition: all 1s ease; padding: 4px; }
#menu:hover {max-height: 75%; overflow: auto}
The reason I have the 'overflow: auto' when on a smaller screen is due to the entire menu not showing when on a smaller screen - even when I have some elements not showing on mobile screens.
The problem I'm running into is when it DOES overflow and the user scrolls through the menu, when they click/hover out of the menu it retracts like it should but it doesn't show the top of the menu anymore, it will show wherever they scrolled to.
I'd like to find a way either via CSS or Javascript to automatically have that div scroll back to the top when the user clicks/hovers out of the menu so it will still show the menu icon + logo instead of random menu text.
I love how it works but can't stand the scrolling issue on smaller screens.

There may be some awkwardness in your idea that might just need a redesign, I certainly have never noticed a menu working like this.
But the jQuery code to scroll to the top is this:
$("html, body").animate({
scrollTop: 0
}, 600);
Where 600 is how long it takes in ms.
You'll have to wrap this in a click() function or something so it triggers when someone presses a menu option.
For example:
$('#menu a').click(function () {
$("html, body").animate({
scrollTop: 0
}, 600);
});
And of course all of this code should be wrapped in a $(document).ready() (basic jQuery setup)
I know you didn't mention jQuery in your question, but this is a popular approach to solving problems like this.

There is another way to achieve auto scroll on click using html only.
You just need to add an id to some div (the header maybe) and on the link you pass the #id to the href like so:
html
<div id="Header">your header</div>
Go to the top
css
/* Keyword values */
scroll-behavior: auto;
scroll-behavior: smooth;
I'd suggest to try out the scroll-behavior: smooth; it makes the transitions, well... smooth :D
Here you can find all the documentation you need about this solution

Detatching a scrolling nav bar from the rest of the scrolling site

I've got a twitter bootstrap parallax template (purchased) - specifically regarding the nav bar, the way it currently works is when you click a nav menu item, the nav bar scrolls up with the rest of the site, then reappears further down the page and remains fixed at the top. What I'd like is for it to not scroll up in the first instance, and just remain fixed at the top the whole time.
This is the site in testing:
http://realestatemediafactory.com/test/
One thing I did try was wrapping the entire nav bar in the code below:
<div data-spy="affix" data-offset-top="160">
But the result was messy, and I figured it better to switch off/modify the code causing the scroll rather than try to cancel it out with more code...
Unsure whether this is controlled by css or jquery, so have not copied any of my code here... whatever's needed I'm happy to paste here.
Thanks guys!!

I don't know if I understand correctly your question and if this will help you
With firebug I tried to edit the css code
Search in your css code this selector and try to modify it so
.navbar-fixed-top .navbar-inner, .navbar-static-top .navbar-inner {
background: url("../img/line_bg.png") repeat scroll left top rgba(0, 0, 0, 0.3);
border-bottom: medium none;
box-shadow: none;
filter: none;
padding-bottom: 10px;
padding-top: 10px;
position: fixed;
transition: padding 0.5s ease-in-out 0s;
width: 100%;
z-index: 1030;
}
With this modification, the navigation bar should always remain fixed at the top
Again: i've only tried with firebug so I'm not sure of the result
If this solution does not suit your needs, i apologize for making you lose time.

Mate thank you very much for your help - I did try that and it solved the problem for the most part, but there was still a positioning issue. I actually found there were two css classes for the header, one fixed and one scrolling, which were controlled by a script which switched between them depending on the position of the page. I turned off the script and that has solved the problem. The script I switched off is below. Thanks again for your help!
<script>
var navbar = jQuery('#navbartop');
var navbartop = jQuery('#topnavbar');
jQuery(window).scroll(function () {
if (jQuery(this).scrollTop() > 640) {
navbar.addClass("navbar-scroll");
navbartop.removeClass("navbar-static-top");
navbartop.addClass("navbar-fixed-top");
} else {
navbar.removeClass("navbar-scroll");
navbartop.removeClass("navbar-fixed-top");
navbartop.addClass("navbar-static-top");
}
});
</script>

How can I make a waiting icon appear in the middle of my page with twitter bootstrap 3?

I looked through all the documentation but still cannot find an example. What I would like to do is to have a waiting icon appear in my page when it's doing an Ajax call. Can someone tell me how I can do this with twitter bootstrap.
Also if there are any other non-jquery implementations which are better I would also like to know about those.
Thank you.

Just pick an loading icon (gif) from font-awesome for bootstrap,
show before the ajax call
hide once the ajax response is delivered
To position the icon in the middle of the screen, use the following css
.ajaxLoader {
position: absolute;
top: 50%;
left: 50%;
width: 500px;
height: 500px;
margin-top: -250px; /* Half the height */
margin-left: -250px; /* Half the width */
}
Also take a look for button loading images
JSFiddle

If you want something dead center, you can use the absolute position technique.
To do it, create a div and give it these attributes:
margin:auto;
position:absolute;
top:0;left:0;bottom:0;right:0;
width:<however wide the image is>;
height:<however big the image is>;
This will put it smack bam in the center no matter when someone resizes the screen, making it work on mobiles as well as desktops (as long as the image isn't huge).
If you want this to work inside another div, make sure that the parent is position:relative;

You can add a bootstrapmodal with your waiting logo,
unbind theclose event,
and close the modal when your ajax call is ended...
