I am trying to create a Single page application.  html content:  &lt;div class="containerDiv"&gt;   &lt;div class="headerDiv"&gt;&lt;/div&gt;   &lt;div class="contentDiv"&gt;&lt;/div&gt;   &lt;div class="footerDiv"&gt;&lt;/div&gt; &lt;/div&gt;   All my application content will go inside contentDiv along with ng-view.  css content:  .containerDiv { position: relative; min-height: 100%; background-color: beige; }  .headerDiv { height: 60px; background: black; width: 100%; }  .contentDiv { padding-bottom: 60px; }  .footerDiv { position: absolute; left: 0; bottom: 0; right: 0; background-color: pink; width: 100%; height: 60px; }   Everything works fine with non-positioned elements and footer stay at the bottom, when content height increases.  I want to add positioned elements(absolute or relative) in the contentDiv as per my requirements.  When height of my positioned element increases, it breaks my page as footer remains at same position and elements overrides it.  Suppose I want to add a table in contentDiv  &lt;div class="data"&gt;    &lt;table&gt;    &lt;/table&gt; &lt;/div&gt;   I want to align table at particular location in html.  .data{  position:absolute/relative;  top: 300px;  left: 400px; }   If height of the table increases, it will go out of the scope of footer. The height of the table is dynamic.
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.

Fill an $n \times n$ matrix with the symbols $\{a,b,c,d\}$ subject to the following:     Only the symbol $a$ appears to the left or above an $a$    Only the symbol $b$ appears to the right or above a $b$    Only the symbol $c$ appears to the left or below a $c$    Only the symbol $d$ appears to the right or below a $d$     Here are some examples of a valid fillings: $$\left( \begin{matrix} a &amp; a &amp; b  &amp; b \\ a &amp; a &amp; b &amp; b \\ c &amp; c &amp; c &amp; d \\  c &amp; c &amp; c &amp; d  \end{matrix}\right) $$  $$\left( \begin{matrix} a &amp; a &amp; a  &amp; a &amp; a &amp; b  &amp; b \\ a &amp; a &amp; a  &amp; a &amp; a &amp; b  &amp; b \\ a &amp; a &amp; a &amp; d &amp; d &amp; d &amp; d \\  a &amp; a &amp; a &amp; d &amp; d &amp; d &amp; d\\a &amp; a &amp; d &amp; d &amp; d &amp; d &amp; d\\c &amp; c &amp; d &amp; d &amp; d &amp; d &amp; d\\  c &amp; c &amp; d &amp; d &amp; d &amp; d &amp; d  \end{matrix} \right) $$  What I have done: We'll it is clear to me that the $a$'s (for example) make up a sort of Young Diagram just by the property above. But there is more to the problem than that. If your YT for $a$ is just a square, then you might have a reversed (right justified) YT available to place for the $b$'s. Details like this seem to make this a tricky problem for me. I am intrigued by this problem and I just thought I'd share it here in case there is some easy way to do this counting problem that I've never heard of.  Thanks, Connect Error (2054) - mysql_old_password issue still not solved Error on \usepackage {geometry} text property Knockout js loop up to a value Suppose that $f:\Bbb R\to \Bbb R$ is continuous and that $f(x)\to 0$ as $x\to \pm\infty$. Prove that $f$ is uniformly continuous.   Since $f(x)\to 0$ as $x\to \pm\infty$ we have $|f(x)|&lt;\epsilon $ whenever $x&lt;-K$ and $x&gt;K$ where $K&gt;0$.  Also $f$ is uniformly continuous on $[-K,K]$ as the domain is compact.  Hence $f$ is uniformly continuous in $(-\infty,-K)\cup [-K,K]\cup (K,\infty)$.  But how to conclude that $f$ is uniformly continuous on $\Bbb R$ from above as I may chose $x\in (-\infty,-K);y\in [-K,K]$ ,how to conclude that $|f(x)-f(y)|&lt;\epsilon $ from above for a given $\epsilon$?  Please suggest the edits required. Create ColorRamp How can I create a ColorRamp for a Cycles material through Python?  I am able to create a new shader output node with nodes.new(type='ShaderNodeOutputMaterial'). Searching online, I see that it is only possible through C code (however, these pages dates back several years).  Is there a way to fake a ColorRamp (maybe with multiple Math nodes in greater/less than mode) or create a ColorRamp for a Cycles material through Python? How to prove that derivatives have the Intermediate Value Property Convert a Bitmap to GrayScale in Android Multiple Inheritance in C# Since multiple inheritance is bad (it makes the source more complicated) C# does not provide such a pattern directly. But sometimes it would be helpful to have this ability. For instance I'm able to implement the missing multiple inheritance pattern using interfaces and three classes like that: public interface IFirst { void FirstMethod(); } public interface ISecond { void SecondMethod(); }  public class First:IFirst  {      public void FirstMethod() { Console.WriteLine(&quot;First&quot;); }  }  public class Second:ISecond  {      public void SecondMethod() { Console.WriteLine(&quot;Second&quot;); }  }  public class FirstAndSecond: IFirst, ISecond {     First first = new First();     Second second = new Second();     public void FirstMethod() { first.FirstMethod(); }     public void SecondMethod() { second.SecondMethod(); } }  Every time I add a method to one of the interfaces I need to change the class FirstAndSecond as well. Is there a way to inject multiple existing classes into one new class like it is possible in C++? Maybe there is a solution using some kind of code generation? Or it may look like this (imaginary c# syntax): public class FirstAndSecond: IFirst from First, ISecond from Second { }  So that there won't be a need to update the class FirstAndSecond when I modify one of the interfaces.  EDIT Maybe it would be better to consider a practical example: You have an existing class (e.g. a text based TCP client based on ITextTcpClient) which you do already use at different locations inside your project.  Now you feel the need to create a component of your class to be easy accessible for windows forms developers. As far as I know you currently have two ways to do this:  Write a new class that is inherited from components and implements the interface of the TextTcpClient class using an instance of the class itself as shown with FirstAndSecond.  Write a new class that inherits from TextTcpClient and somehow implements IComponent (haven't actually tried this yet).   In both cases you need to do work per method and not per class. Since you know that we will need all the methods of TextTcpClient and Component it would be the easiest solution to just combine those two into one class. To avoid conflicts this may be done by code generation where the result could be altered afterwards but typing this by hand is a pure pain in the ass.

If so, how? Let , $\Delta = B(0,1)$.  If $f:\Delta \rightarrow \Delta$ is holomorphic, and $f(0)=0$, prove that $|f(z)+f(-z)| \leq 2|z|^2$.  My attempt so far:  $\displaystyle f(z) = \sum_{n=0}^{+\infty} a_n z^n = \sum_{n=0}^{+\infty} a_{2n} z^{2n} + \sum_{n=0}^{+\infty} a_{2n+1} z^{2n+1}$  $\displaystyle f(-z) = \sum_{n=0}^{+\infty} a_n (-z)^n = \sum_{n=0}^{+\infty} a_{2n} z^{2n} - \sum_{n=0}^{+\infty} a_{2n+1} z^{2n+1}$  Then, $\displaystyle f(z)+f(-z) = 2  \sum_{n=0}^{+\infty} a_{2n} (z^2)^n =: 2 g(z^2)$  If $g(\Delta) \subset \Delta$, as $g(0) = 0$, I can invoke Schwarz Lemma and I win. However, I don't know how to prove this. Could anyone help me? Thanks! It is currently said that MD5 is partially unsafe. Taking this into consideration, I'd like to know which mechanism to use for password protection.  This question,   suggests that hashing multiple times may be a good idea, whereas  suggests using salt.  I'm using PHP. I want a safe and fast password encryption system. Hashing a password a million times may be safer, but also slower. How to achieve a good balance between speed and safety? Also, I'd prefer the result to have a constant number of characters.   The hashing mechanism must be available in PHP It must be safe It can use salt (in this case, are all salts equally good? Is there any way to generate good salts?)   Also, should I store two fields in the database (one using MD5 and another one using SHA, for example)? Would it make it safer or unsafer?  In case I wasn't clear enough, I want to know which hashing function(s) to use and how to pick a good salt in order to have a safe and fast password protection mechanism.
