Sometimes on my site, that have few lines of text or very less content.  In such cases, the footer displays below the content somewhere between the page. That does not give a nice look to the page.  Like this:    When I add a css:  .ar-footer{    position:absolute;    bottom:0px;    left:0px;    right:0px;    width:100%;  }   The footer content is changed. Like this:    how to fix it? I want to fix the footer section into bottom of the pages if the content is less or more.
I have a simple 2-column layout with a footer that clears both the right and left div in my markup.  My problem is that I can't get the footer to stay at the bottom of the page in all browsers.  It works if the content pushes the footer down, but that's not always the case.
Why did Dumbledore 'put on' the Resurrection Stone (Ring)? Does "Root A" follow the fact about Takatsuki and the One-Eyed Owl? In Root A, Takatsuki does seem to be fascinated by Kaneki's name, but,      I didn't at all expect her to be the One-Eyed Owl.   I just looked her up on the  and it says that       she is the One Eyed-Owl as well as the horror novelist.   Is this true only in the manga or is it also true in Root A? Reproducible LaTeX builds - compile to a file which always hashes to the same value Is there any rule for differentiating between the endings "th" and "ht"? Some words end in th (length, width), and others end in ht (height, fight, tonight, caught).    I sometimes have difficulties in spelling such words because I don't know which ending to choose. Is there any rule or pattern (even localized) in choosing one or the other?

Partition around bad drive sectors? I've seen a lot of hard drives with only a few bad (unrecoverable) sectors (as indicated by SMART). Of course the proper thing to do with a bad drive is replace it, as there's a good chance of the drive crashing completely in the near future; I'm aware of that. However, in the interim, or for those who don't want to spend $70 to save data they don't value highly anyway (sigh, non-technical people), or just to get some use out of old hardware instead of throwing it away, I'm wondering if there's a way to identify where the unrecoverable sectors are ("where" meaning numerically, from 0 to the number of sectors on the drive), so I could stick a blank partition in that general area. Yes, this would involve low-level-formatting the drive and reinstalling the OS, of course.  So:  Would partitioning around unrecoverable sectors even be a workable way of reducing the disk of losing data?  If so, is there a way to find the location of these unrecoverable sectors? Do I need both a UK visa and a Schengen visa? Let $D$ be an integral domain and let $a^m=b^m$ and $a^n=b^n$ where $m$ and $n$ are relatively prime integers, $a,b \in D$.   How do I show $a=b$? How many seconds count until bomb detonates in Counter Strike? In Counter-Strike, is there any count (in seconds/minutes) until the bomb explode when it's first set-up? And can the timing be modified? Is there any bidirectional 5v-3.3v level shifter? Is there any IC that interfaces any 3.3V Input/Output to 5V Output/Input? I need it primarily for an Arduino Due but if there any bidirectional IC that works like that it would be great.  Some people advised me to use the SN74AHC125 and CD4050 ICs, but I don't understand how they work or how to interface with them. HUD is not working after upgrade My HUD is not working after I upgraded from 11.04 (and or 11.10).  It prompts for command and it tries loading for 4 seconds then gives up. Is there a way to forget node names between TikZ pictures? I have a document with several TikZ pictures in it.  I generally use simple names for the nodes such as:  \node (A) at .....  \node (B) at .....   and so forth.  Because of this I have name clashes between the various pictures.  That's generally not a problem.  However I find myself in a position where I may or may not have defined a certain node within a given picture.  So I use the following snippet to test whether the node has been defined:  \makeatletter \long\def\ifnodedefined#1#2#3{%%   \@ifundefined{pgf@sh@ns@#1}{#3}{#2}} \makeatother   Unfortunately this fails if I've already created a node by the same name in another picture.  Is there a way to scope the definitions of nodes or is there a way to undefine nodes once you no longer need them?  P.S.  I'm aware that I could embed each picture in a standalone file and import it using \includegraphics.  Unfortunately, this approach will not work for the document I'm creating.

Is there a way to tell an &lt;a&gt; tag to always use the http protocol instead of the https protocol (or the other way around)? I know it´s easy using the complete link ( or ), but I would like it to work with relative links (index.html, ../index.html, etc.). Showing that $f:(0,2\pi]\to S^1$ is not a homeomorphism I want to show that $f:(0,2\pi]\to S^1$ defined by $t\to (\sin t, \cos t)$ is not a homeomorphism. I will do this by showing that its inverse is not continuous.    The inverse is defined by $(\sin t, \cos t)\to t$. So at $(0,1)$ we want to have $\lvert 2(1-\cos t)\rvert &lt;\delta \Rightarrow \lvert t-2\pi\rvert&lt;\epsilon$ for any $\epsilon$. If we take $\epsilon=\pi/2$, no matter how close $\cos t$ and $1$ are there will always be $t$'s close to $0$. So $f^{-1}$ is not continuous.  What do you think? Are there any mistakes? I have iterate over numbers in various order. I am able to display them in increasing order, even with steps like:  $ seq --separator="," 1 10 1,2,3,4,5,6,7,8,9,10 $ seq --separator="," 1 2 10 1,3,5,7,9   I am also able to display them in reverse order, neither continuous nor step wise.  $ seq --separator="," 10 1    $ seq --separator="," 10 2 1   No output for above commands.

Order of some quotient ring of Gaussian integers Limit as $x\to 0$ of $\frac{(1+x)^{1/x}-e}{x}$ What is the difference between == and ===?  How exactly does the loosely == comparison work?

BibTeX loses capitals when creating .bbl file Titles of articles I'm about to cite contain upper case letters and when using BibTeX it converts them to lower case ones. This happens only in the title and only the first letter conserves its case. For example, when I cite an article about HF, the reader won't know if it is about Hafnium (Hf) or fluorine acid (HF).  I know that I can fix it manually in the .bbl file but I would like to avoid it, or fix it automatically.
