html - Div alignments in CSS -

-

i have alignment in image based on number of sub divs, using css/html , bootstrap.

  1. full width can hold upto 3 divs (i.e. .container)
  2. if 2 divs shown should center aligned.

as of now, divs align left or right.

what easy way achieve css/html? not sure keywords should search on google - there lot of articles talking centering divs.

enter image description here

set div inline-block , wrapper text-align: center:

.wrapper { text-align: center; }  .wrapper div {    width: 100px;    height: 100px;    background: red;    display: inline-block;    margin: 20px;  }
<div class ="wrapper">    <div></div>    <div></div>    <div></div>  </div>  <div class="wrapper">    <div></div>    <div></div>  </div>

python - RuntimeWarning: PyOS_InputHook is not available for interactive use of PyGTK -

i'm using pygtk python 2.7 in ubuntu 14.04, following message: runtimewarning: pyos_inputhook not available interactive use of pygtk what reason ? when trigger? trying run script or use pygtk interactively? most likely, input hook grabbed interactive loop, e.g.: >>> import tkinter >>> root = tkinter.tk() # input hook grabbed tkinter immediate result evaluation >>> import gtk # gtk tries grab hook, fails /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:127: runtimewarning: pyos_inputhook not available interactive use of pygtk the immediate result evaluation means expression results evaluated (e.g. window displayed) before entering main loop. have in mind, warning, not error, if bothers you, can import gtk module can (or, well, reasonably early) , release input hook: import gtk gtk.set_interactive(false) import tkinter root = tkinter.tk() # no warning here
