由 ≯℡__Kan透↙ 提交于 2019-12-13 00:27:01
问题 I've got three unequal length columns of text and I want to put a button at the bottom of each column. I'm looking for a current method--preferably CSS only--of positioning the buttons so that they're at the same vertical position in the page when the columns are side-by-side (floated), and then are positioned after the relevant column when the layout is single column (on small screens). I don't necessarily need the columns to be equal length since they don't have backgrounds, unless that's

JPA @JoinTable - Three ID Columns

由 ⅰ亾dé卋堺 提交于 2019-12-12 21:29:35
问题 I have a situation that is quite similar to the one outlined in this question's diagram: JPA. JoinTable and two JoinColumns, although with different issues. I have three tables: Function , Group , and Location . Currently, I have a join table set up between Location and Group using @JoinTable . It is @ManyToMany on both sides, and works perfectly fine. I am attempting to add the constraint that no Location should be associated with more than one Group that has the same Function . So I added a

Multi-column lists in Bootstrap/Foundation

由 梦想与她 提交于 2019-12-12 16:23:42
问题 I am trying to figure out the best way to create vertical multi-column lists in a grid framework like Bootstrap or Foundation. I already know how to do this in a couple of ways, but the way I want it I am not sure is possible to do with just CSS. I need the li tags to come directly after the ul tag without a col-*-* divs between. To best describe what I want, I'll first show most people would roughly go about a 3 column list: <ul class="row"> <li class="col-sm-4">A</li> <li class="col-sm-4">B

问题 I have a specific series of datasets which come in the following general form: import pandas as pd import random df = pd.DataFrame({'n': random.sample(xrange(1000), 3), 't0':['a', 'b', 'c'], 't1':['d','e','f'], 't2':['g','h','i'], 't3':['i','j', 'k']}) The number of tn columns ( t0, t1, t2 ... tn ) varies depending on the dataset , but is always <30. My aim is to merge content of the tn columns for each row so that I achieve this result (note that for readability I need to keep the whitespace

IE (11) improper handling of CSS multi-columns?

由 喜你入骨 提交于 2019-12-12 09:04:59
问题 I'm building a 2-column layout using CSS multi-columns, and I want to give a hint as to where to break the columns. So I say: columns: 2 on the container, and break-before: column on the child where I want the break. IE (11 in my case) decides to split my content into 3 columns and overflows to the right of its box :-( Chrome (using the prefixed alternatives -webkit-columns:2 and -webkit-column-break-before: always ) behaves nicely. Fiddle at: http://jsfiddle.net/jDecq/6/ Am I doing something

How to make div same height as parent (displayed as table-cell)

由 浪尽此生 提交于 2019-12-12 07:24:32
问题 I got a container div containing three child divs (vary in content) - each as tall as the tallest one. I managed this by setting the container to display:table and the child divs to display:table-cell etc. Everything worked just fine, until... I inserted a new div inside one of the child divs and tried to make it height:100% - so it would stretch to the same height as its parents, but that did not work. Please see my JSFiddle: http://jsfiddle.net/bkG5A/ Any help would be greatly appreciated!
