问题 This question already has answers here : Why does my image have space underneath? (3 answers) Closed 4 years ago . I want to lay out a grid by appending divs to body and letting them wrap around the screen. Why am I getting spacing between the rows? It remains regardless of margin & padding; see below image. Here is the markup: <!DOCTYPE html> <html> <head> <script src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js' type='text/javascript'></script> </head> <body> <style>

Remove EOL spaces of selection only if there are

由 只谈情不闲聊 提交于 2019-12-11 04:35:44
问题 How do I check if a selection has EOL spaces and remove them only if there are? I need to remove the EOL spaces of a selection in order to do an other operation. I would like to check if there are but don't know how to do this. 回答1: You can suppress errors in the :substitute command using the e flag. So eckes' suggestion would become: :'<,'>s/\ \+$//ge Then any errors are ignored, and scripts are not interrupted. See :help s_flags for more information. If you really want to check if there are

How to change the space between bars in geom_bar?

由 廉价感情. 提交于 2019-12-11 04:04:41
问题 I have a bar plot with positive values on both sides. When I changed the width of the bars, the space between them became to large and doesn't look good. I tried to manipulate this with position = position_dodge , but it doesn't work. How can I reduce the spaces between the bars? Here is the code (originally posted here Stacked barplot crossing the x-axis) with my data: Year <- factor(c("2003-2009","2003-2009","2003-2009","2003-2009","2003-2009","2009-2012", "2009-2012","2009-2012","2009-2012

Memory allocation of base class and derived class constructor

由 北慕城南 提交于 2019-12-11 04:01:27
问题 For which one the space is allocated first when the derived class object is created? whether base class constructor or derived class constructor? 回答1: First, allocation , the reservation of memory which you’re asking about, is different from and precedes initialization (execution of a constructor that essentially sets suitable values in that memory), and the formal (our Holy Standard) and the in-practice differ on whether memory for a most derived object needs to be contiguous , with the

Removing the padding between inline elements

由 一个人想着一个人 提交于 2019-12-11 03:33:20
问题 I have two span tags that contain content. The first span tag will hold content from the client and the second acts like a "blipping-cursor" (I'm using JavaScript to turn its "display" style from inline to none every 500 milliseconds). Currently, everything works great except for the fact that there is a bit of spacing (just a bit in IE and a TON (one or two spaces worth) in Webkit (nested parenthesis for the win!))) between the content in the first span and the second span. So my question is

Python: A character that appears to be a space but isn't a space. What is it?

问题 This is in Python 3.4. I'm writing my first program for myself and I'm stuck at a certain part. I'm trying to rename all of my audio files according to its metadata in python. However, when I try to rename the files, it doesn't finish renaming it sometimes. I think it is due to an invalid character. The problem is that I don't know what character it is. To me, it looks like a space but it isn't. My code is here: from tinytag import TinyTag import os print("Type in the file directory of the
