Answer : There is no centering environment. And issuing \centering inside \resizebox doesn't make sense anyway: it should be outside, because you want to center the resized box. \documentclass[11pt,english,titlepage]{article} \usepackage{graphicx} \begin{document} \begin{table} \centering \caption{mytable} \resizebox{.5\textwidth}{!}{% <------ Don't forget this % \begin{tabular}{rrr} A & B & C \\ \hline A1 & B1 & C1 \\ A2 & B2 & C2 \\ A3 & B3 & C3 \\ \end{tabular}% <------ Don't forget this % } \end{table} \end{document} Here an alternative answer using adjustbox . It covers the functionality of \resizebox and is also able to center its content. It also removes the need of escaping the line breaks with % as seen in egregs answer, as the adjustbox environment removes the spaces added by them. It is even possible to pr...

Example 1: how to genrate a random number in C # include <time.h> # include <stdlib.h> srand ( time ( NULL ) ) ; // Initialization, should only be called once. int r = rand ( ) ; // Returns a pseudo-random integer between 0 and RAND_MAX.

Answer : I think problem is in placement rather then overlay, div.desc is absolute and image is its sibling. So overlay will not follow image it will follow only anchor tag or your div.wrapper . From what I can see is that there is a margin on image or padding in anchor or wrapper. The best solution is to put desc and image in another div with 100% width with 0 padding. <div class="col-sm-4 wrapper"> <a href="#"> <div class="fix"> <img src="images/upload/projects/21/wolf.jpg" class="img-responsive" alt="" /> <div class="desc"> <p class="desc_content">The pack, the basic unit of wolf social life.</p> </div></div> </a> </div> CSS: .fix{width:100%; padding:0px;} For others trying to overlay a caption on an image in Bootstrap, consider using carousel captions.

Answer : This worked for me, mWebView.setBackgroundColor(Color.TRANSPARENT); At the bottom of this earlier mentioned issue there is an solution. It's a combination of 2 solutions. webView.setBackgroundColor(Color.TRANSPARENT); webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null); When adding this code to the WebViewer after loading the url, it works (API 11+). It even works when hardeware acceleration is ON I had the same issue with 2.2 and also in 2.3. I solved the problem by giving the alpa value in html not in android. I tried many things and what I found out is setBackgroundColor(); color doesnt work with alpha value. webView.setBackgroundColor(Color.argb(128, 0, 0, 0)); will not work. so here is my solution, worked for me. String webData = StringHelper.addSlashes("<!DOCTYPE html><head> <meta http-equiv=\"Content-Type\" " + "content=\"text/html; charset=utf-8\"> </head><body><di...

Answer : You can use a tool for creating generic icons in Asset Studio: https://romannurik.github.io/AndroidAssetStudio/icons-generic.html. To get it look like ActionBar Icon, you should make next actions: Choose image The size of image should stay at 24dip Change padding to 4dip Move foreground color thumb to 0% That's it! Download .zip now. The sizes of icons will be pretty the same as you can get them with ActionBar Icon Generator. How it looks for me: I think it's because your image is too complexe and the main problem is the "color" filter applied in AAS. I had the same problem and I had to convert xxxhdpi xxhdpi etc. manually. If you work with Sketch (for example) it can be converted easily with a plugin (https://github.com/zmalltalker/sketch-android-assets) hope it's help ! If you want to use AAR, like @rom4ek explained "4. Move foreground color thumb to 0%" this is the important part

Answer : A real working solution with no other dependencies than angularjs (tested with v.1.0.6) html <input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/> Angularjs (1.0.6) not support ng-model on "input-file" tags so you have to do it in a "native-way" that pass the all (eventually) selected files from the user. controller $scope.uploadFile = function(files) { var fd = new FormData(); //Take the first selected file fd.append("file", files[0]); $http.post(uploadUrl, fd, { withCredentials: true, headers: {'Content-Type': undefined }, transformRequest: angular.identity }).success( ...all right!... ).error( ..damn!... ); }; The cool part is the undefined content-type and the transformRequest: angular.identity that give at the $http the ability to choose the right "content-type" and manage the bounda...

Answer : You can indirectly check to see if it exists by trying to set it to a value with javascript if it can't be set, then the HTTP Only Cookie must be there (or the user is blocking cookies). function doesHttpOnlyCookieExist(cookiename) { var d = new Date(); d.setTime(d.getTime() + (1000)); var expires = "expires=" + d.toUTCString(); document.cookie = cookiename + "=new_value;path=/;" + expires; if (document.cookie.indexOf(cookiename + '=') == -1) { return true; } else { return false; } } No. And see Rob's comments below. See this, which you probably already saw - http://en.wikipedia.org/wiki/HTTP_cookie#Secure_and_HttpOnly An HttpOnly cookie is not accessible via non-HTTP methods, such as calls via JavaScript (e.g., referencing "document.cookie")... Edit: Removed undefined response, I wrote a script that you may not be using :) I had the same problem. I solved it with the server setting anoth...
