Bootstrap 4 Flexbox with Fixed and Flexible Width Columns

阅读更多关于 Bootstrap 4 Flexbox with Fixed and Flexible Width Columns

问题 Using Bootstrap 4 and Flexbox, how would you accomplish a 2 column layout with a fixed-width left column and a flexible right column? I don't see anything in the docs about how to achieve this... I could do it easily enough using vanilla CSS, but I feel like I should use Bootstrap since I'm already pulling it in. 回答1: Is this what you are looking for: HTML CODE---->> <div class="main-container"> <div class="left"> Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Convert fixed width txt file to CSV / set-content or out-file -append?

阅读更多关于 Convert fixed width txt file to CSV / set-content or out-file -append?

问题 Input file is a fixed-width txt file. My client normally opens it in Excel and manually specifies the column breaks. I'm hoping to replace certain blank spaces with a comma, so that I can parse as CSV and save as XLS or whatever. $columBreaks = 20, 35, 50, 80, 100, 111, 131, 158, 161, 167, 183 [array]::Reverse($columBreaks) #too lazy to re-write array after finding out I need to iterate in reverse $files = get-childitem ./ |where-object {$_.Name -like "FileFormat*.txt"} foreach($file in

Why doesn't a fixed-width element take up the space beside a floated element?

阅读更多关于 Why doesn't a fixed-width element take up the space beside a floated element?

问题 In this CodePen, the <aside> element wraps the <article> element. But if you apply a width to the <aside> element (i.e. uncomment width: 50px; ), the <aside> jumps to a new row, even though there is enough space to sit alongside the <article> element. Why doesn't the element sit alongside a floated <article> when space is available? section { width: 800px; } article { float: left; width: 500px; background: #ffffcc; } aside { /* width: 50px; */ background: #ccffcc; } <body> <section> <article>

How to keep <li> elements on single line in fixed width <ul>?

阅读更多关于 How to keep elements on single line in fixed width ?

问题 I've a header div and a menu ul below it. I'd like to accomplish 2 things: 1) the ul should have the same width as the div (outer vertical borders exactly same x position 2) I'd like to keep the spacing between li elements roughly equal With some trial and error on the li 's margins and padding I roughly achieved the first point in Google Chrome (please see this jsfiddle) but in Firefox the li 's don't fit in the ul so they don't stay on a single line. Also, the last li tends to 'spill over'

Fixed width number formatting python 3

阅读更多关于 Fixed width number formatting python 3

问题 How do I get an integer to fill 0's to a fixed width in python 3.2 using the format attribute? Example: a = 1 print('{0:3}'.format(a)} gives ' 1' instead of '001' I want. In python 2.x, I know that this can be done using print "%03d" % number. I checked the python 3 string documentation but wasn't able to get this. http://docs.python.org/release/3.2/library/string.html#format-specification-mini-language Thanks. 回答1: Prefix the width with a 0 : >>> '{0:03}'.format(1) '001' Also, you don't need

Python Pandas, write DataFrame to fixed-width file (to_fwf?)

阅读更多关于 Python Pandas, write DataFrame to fixed-width file (to_fwf?)

问题 I see that Pandas has read_fwf , but does it have something like DataFrame.to_fwf ? I'm looking for support for field width, numerical precision, and string justification. It seems that DataFrame.to_csv doesn't do this. numpy.savetxt does, but I wouldn't want to do: numpy.savetxt('myfile.txt', mydataframe.to_records(), fmt='some format') That just seems wrong. Your ideas are much appreciated. 回答1: Until someone implements this in pandas, you can use the tabulate package: import pandas as pd

Fluid or fixed grid system, in responsive design, based on Twitter Bootstrap

阅读更多关于 Fluid or fixed grid system, in responsive design, based on Twitter Bootstrap

问题 I'm getting confused about the various options in the twitter bootstrap grid, and how they go together. To begin with, you can have an ordinary fixed container , or a container-fluid . Then either one can include either an ordinary row , or a fluid row, row-fluid . That is, you can have a fixed container with a fluid row, or a container-fluid... with a fixed row? Then on top of that, you can include the 'responsive' media queries, or not. I am getting confused as to how these things interact.
