I'm making an animation that effects a class of menu's, It slides the menu in and out the left side of the screen. But because I change the width value for another part of the app, I have to look into the css somehow,  This is what I have in CSS:   width (600px (dependant on device with))    Using Javascript I change:   Width (a relative amount) left (-width)   The left is easy, because I can just do -element.offsetWidth But the width is harder, because I don't know how much it's going to change, and I don't want to hardcode it in either.  Does anyone know a way that lets me look into the elements css, before it's changed? (as it's written in code)  What I've tried so far:   element.offsetWidth (Didn't work because it returns the current width and not the width written in the css) element.style.width (Didn't work because it returns an empty string)        NOTE:    There is a similar question , but the answer gives the current width, and I want the width that's set by the CSS (while loading the document)   Simplified code:
Suppose that I have a &lt;div&gt; that I wish to center in the browser's display (viewport). To do so, I need to calculate the width and height of the &lt;div&gt; element.   What should I use? Please include information on browser compatibility.
I am trying to connect my Galaxy Tab to the Internet through an ad-hoc network made via my PC. The PC ad-hoc settings are fine because I can use it from my iPhone and other devices. Why does no one notice the Joker's presence as a policeman during the mayor's speech? It is often stated that the Lagrangian formalism and the Hamiltonian formalism are equivalent.   We often hear people talk about eigenvalues of Hamiltonians but I have never ever heard a word about eigenvalues of Lagrangians.   Why is this so? Is it not useful? is it not possible to do it? How do I wire two lights with a switch? I'd like to manage my home machines and laptops with Landscape, how can I do this? I don't see the gear button next to the Sign in button at the login screen. I have Nvidia drivers installed (for Nvidia 730 GT card). Ubuntu boots into Xorg as seen from the terminal with echo $XDG_SESSION_TYPE which outputs x11.  How do I switch to Wayland? When I search for Chromium in Ubuntu Software on Ubuntu 16.04, There are 2 options.    Which one should I select?    The same can be observed with , ,  etc. How should I structure my URLs for both SEO and localization? When my phone MOTOROLA G3(2015) is updated to Marshmallow, its not showing files when connected to PC. While connecting, it shows options as charing only, PTP, MTP, MIDI. When I select MTP, it shows the external card, but not showing the contents, where as internal memory is detected and all files are shown. How do I deliver a baby? I'm playing Fallout Shelter, and my newest bonus objective is to "Deliver 1 Baby Dweller."  I've already figured out that I can put a male vault dweller and a female vault dweller together in some residential quarters, and and eventually, if they hit it off, the lady will replace her vault suit with a yellow sweater and a decidedly pregnant figure.   Good enough.  But how long does it take her to deliver the child? Do I have to induce it through some sort of tapping ritual or placing her in the correct room? Does the pregnant dweller need to stay in the living quarters, or can I put her to work in my Diner or Water Treatment Facility? Do the SPECIAL stars of the parents matter?  Tell me everything about  and what I can do to control the process. What is the use of the square brackets [] in sql statements? I've noticed that Visual Studio 2008 is placing square brackets around column names in sql. Do the brackets offer any advantage? When I hand code T-SQL I've never bothered with them.  Example:  Visual Studio:  SELECT [column1], [column2] etc...   My own way:  SELECT column1, column2 etc... Clicking to reload an updated answer removes the code snippet buttons and removes syntax highlighting Does Kylo not know the fate of Darth Vader? It seems Kylo has an obsession of Darth Vader and has an interest in the dark side because of it.   Does he not realize that Darth Vader turned good and helped destroy the Empire (Spoilers?)? I feel like Kylo would've seen how much better the Light Side was as it was able to turn Vader from the Dark Side if he had known this. What is the order of the Crisis on Earth X episodes in the Arrowverse? What's wrong with these two cron jobs?

But when I checked the running of the script this morning I got an e-mail stating (I'm paraphrasing because I accidentally deleted them) that the back ticks weren't closed properly. Why do we say there is an overall negative charge on the intracellular side of the plasma membrane at rest, and an overall positive charge on the extracellular side when both potassium and sodium are positively charged ions, and they are in relatively equal amounts on either side? It seems to me that both sides should be positively charged, and I can't get my head around it. When does the placement of a resistor matter? I've been a programmer for years but am very new to electronic engineering. So far I see people saying it doesn't matter where a resistor goes in your LED circuit as long as it is present, but it sounds like that's the nature of the basic LED circuit.  When does the placement of a resistor start to become important? I heard using 'could' is for politeness. When I request something, should I say "Can you please" or "Could you please"? Does the latter sound over-polite and pretentious? I have a simple question regarding "conditional probability" and "Likelihood". (I have already surveyed this question  but to no avail.)  It starts from the Wikipedia . They say this:     The likelihood of a set of parameter values, $\theta$, given   outcomes $x$, is equal to the probability of those observed outcomes   given those parameter values, that is      $$\mathcal{L}(\theta \mid x) = P(x \mid \theta)$$   Great! So in English, I read this as: "The likelihood of parameters equaling theta, given data X = x, (the left-hand-side), is equal to the probability of the data X being equal to x, given that the parameters are equal to theta". (Bold is mine for emphasis).  However, no less than 3 lines later on the same page, the Wikipedia entry then goes on to say:     Let $X$ be a random variable with a discrete probability distribution   $p$ depending on a parameter $\theta$. Then the function      $$\mathcal{L}(\theta \mid x) = p_\theta (x) = P_\theta (X=x), \, $$      considered as a function of $\theta$, is called the likelihood   function (of $\theta$, given the outcome $x$ of the random variable   $X$). Sometimes the probability of the value $x$ of $X$ for the   parameter value $\theta$ is written as $P(X=x\mid\theta)$; often   written as $P(X=x;\theta)$ to emphasize that this differs from   $\mathcal{L}(\theta \mid x) $ which is not a conditional probability,   because $\theta$ is a parameter and not a random variable.   (Bold is mine for emphasis). So, in the first quote, we are literally told about a conditional probability of $P(x\mid\theta)$, but immediately afterwards, we are told that this is actually NOT a conditional probability, and should be in fact written as $P(X = x; \theta)$?   So, which one is is? Does the likelihood actually connote a conditional probability ala the first quote? Or does it connote a simple probability ala the second quote?  EDIT:  Based on all the helpful and insightful answers I have received thus far, I have summarized my question - and my understanding thus far as so:    In English, we say that: "The likelihood is a function of parameters, GIVEN the observed data." In math, we write it as: $L(\mathbf{\Theta}= \theta \mid \mathbf{X}=x)$. The likelihood is not a probability.  The likelihood is not a probability distribution.  The likelihood is not a probability mass. The likelihood is however, in English: "A product of probability distributions, (continuous case), or a product of probability masses, (discrete case), at where $\mathbf{X} = x$, and parameterized by $\mathbf{\Theta}= \theta$." In math, we then write it as such: $L(\mathbf{\Theta}= \theta \mid \mathbf{X}=x) = f(\mathbf{X}=x ; \mathbf{\Theta}= \theta) $ (continuous case, where $f$ is a PDF), and as $L(\mathbf{\Theta}= \theta \mid \mathbf{X}=x) = P(\mathbf{X}=x ; \mathbf{\Theta}= \theta) $ (discrete case, where $P$ is a probability mass). The takeaway here is that at no point here whatsoever is a conditional probability coming into play at all.  In Bayes theorem, we have: $P(\mathbf{\Theta}= \theta \mid \mathbf{X}=x) = \frac{P(\mathbf{X}=x \mid \mathbf{\Theta}= \theta) \ P(\mathbf{\Theta}= \theta)}{P(\mathbf{X}=x)}$. Colloquially, we are told that "$P(\mathbf{X}=x \mid  \mathbf{\Theta}= \theta)$ is a likelihood", however, this is not true, since $\mathbf{\Theta}$ might be an actual random variable. Therefore, what we can correctly say however, is that this term $P(\mathbf{X}=x \mid \mathbf{\Theta}= \theta)$ is simply "similar" to a likelihood. (?) [On this I am not sure.]   EDIT II:  Based on @amoebas answer, I have drawn his last comment. I think it's quite elucidating, and I think it clears up the main contention I was having. (Comments on the image).    EDIT III:   I extended @amoebas comments to the Bayesian case just now as well: What techniques, tricks or otherwise have you used to get upgrades on flights? I've travelled a lot.  Living in New Zealand or the UK means anywhere is likely a flight, but I've always flown economy.  Twice between LA and Auckland I managed to get the exit row after talking nicely to the check-in girl, but apart from that, nothing.  I've spoken to ticket agents, tried 'check in chicken' (where you wait until the last minute before checking in, hoping there's an overbooking of economy) but have never managed to get an upgrade, while others I know seemingly get them quite often.  What strategy have you used or do you suggest to achieve this?  My next flight is from Melbourne to Tokyo, and I plan on trying all of these ;)  (Related questions on  and  upgrades)
