Display a component in a grid pattern. Vue.js - vue.js

I have a card component that I would like to show in rows and columns, I haven't been able to figure it out, I would want to do it without using any dependencies if possible. I want a simple grid like 4 or 5 per row and adding a new row when necessary.
These components are to display the categories created by the user, the amount will change because on this page is where the user can create more, update them or delete the categories.
Right now I'm displaying them simply like this but they're all just one on top of the other
<div v-for="(category, index) in categories" :key="index">
<category_component :category="category" v-on:delete="confirmDelete" v-on:edit="editItem"/>
</div>
Is there a simple way to display them a certain number per row dynamically?
Edit:
I added some flex parameters as suggested like this
<div class="category-container">
<div v-for="(category, index) in categories" :key="index">
<category_component :category="category"
v-on:delete="confirmDelete" v-on:edit="editItem"/>
</div>
</div>
.category-container {
display: flex;
flex-wrap: wrap;
justify-content: space-around;
}
Now it is displaying in rows but is there a way to limit the amount per row? It's displaying 6 but they are really pushed together and then the row below they are far apart. Ignore the new button.

How do i add color to an entire Vuetify Data Table row with dynamic headers

Good day.
I have a data-table divided by groups with dynamic headers that change depending on whatever months the user choose to obtain information from, so i want to get information from the months of January until April i'll have 5 columns, one with the name of my classifications and 4 related to the months i am searching for.
every group has a row called total that summarizes the expenses of each group for each month and i want to be able to color this entire row with a color of my choosing. How would i go about that, especially when i have dynamic headers that change whenever the user searches for a time period?
<v-data-table
dense
:headers="headers"
:items="classifications"
item-key="classification"
group-by="classification_group"
disable-sort
hide-default-footer
disable-pagination
class="elevation-1"
>
<template v-slot:group.header="{items, isOpen, toggle}">
<th colspan=1000000>
<v-icon #click="toggle"
>{{ isOpen ? 'mdi-minus' : 'mdi-plus' }}
</v-icon>
{{ items[0].classification_group }}
</th>
</template>
</v-data-table>
One solution is to apply a class to the "total" row's tr element and have CSS that is applied to this class.
So in my v-data-table template, I have a v-if that detects if the tr element is for a "total" row and, if so, applies a table-row-total class.
Then, in that component's <style> section I apply something like:
.my-table-name .v-data-table tr.table-row-total {
background-color: #ffff00 !important;
}
You may want to double-check the Vuetify data tables API, but to the best of my knowledge, I don't know of a more sophisticated way in Vuetify to handle styling 'special case' rows in a datatable -- so, the method above worked fine for me.

Proper ARIA metatags for responsive table

Im making responsive table and I want it be fully accessible for every people. But in this case i'm not sure where i should use rowheader and where to use columheader.
Here is my code (ofcourse it is just example, there is not actual data):
<div role="grid">
<div class="row" role="row">
<div class="hidden-xs col-sm-offset-4 col-sm-3 " role="columnheader">
<img class="img-responsive" style="width:200px;" src="http://blogmedia.whoishostingthis.com/wp-content/uploads/2013/04/free-hosting.jpg" alt="Vendor 1">
</div>
<div class="hidden-xs col-sm-offset-1 col-sm-3 " role="columnheader">
<img class="img-responsive" style="width:200px;" src="http://jennmoney.biz/assets/free.gif" alt="Vendor 2">
</div>
</div>
<hr class="line">
<div class="raty-table" role="row">
<span class="col-xs-12 col-sm-4" role="rowheader">
Title 1
</span>
<span class="visible-xs-block col-xs-4" role="rowheader">
Vendor 1
</span>
<span class="col-xs-8 col-sm-4" role="gridcell">
Content
</span>
<span class="visible-xs-block col-xs-4" role="rowheader">
Vendor 2
</span>
<span class="col-xs-8 col-sm-4" role="gridcell">
Content
</span>
</div>
</div>
Here is a fiddle:
For vendors should I use rowheader or columnheader? And how I should tag "How long can I sing?" Once it is rowheader and on different screen size it can be columnheader.
I see, it is hard to undestand what I mean, so I made two mocks, but thanks to StackOverflow I can't post it, becouse I have to low reputation...
I must post it as a link: http://postimg.org/gallery/j2elhzmc/ - first picture shows how it looks on desktop, second how it looks at smartphone (if you have the same order as me).
Your grid must be defined as non editable
A grid is considered editable unless otherwise specified. To make a grid read-only, set the aria-readonly attribute of the grid to true.
You should explicitly indicate relationships
If relevant headers cannot be determined from the DOM structure, authors SHOULD explicitly indicate which header cells are relevant to the cell by referencing elements with role rowheader or columnheader using the aria-describedby attribute.
Note that you might reference a "display:none" element in the aria-describedby attribute. I will say that the more semantic choice will then be to set aria-hidden attribute on your rowheader elements.
TL;DR:
Set aria-readonly=true on the grid
Set aria-describedby attribute on your "gridcell" cells referencing each one of your "not always visible" columnheader
Remove role="rowheader" and set aria-hidden="true"
Sorry if I'm missing something obvious but columnheader should be used at the top of each column. (You could have a columnheader in the middle of the table, but that's not typical, although I could see it used as a repeating header if it split across pages.)
A rowheader is usually the first cell in the table for that row. You can have multiple rowheaders but it's not common unless you're showing a multi-dimensional table (eg, a sales report that has a year header for all rows, then quarter headers for every three months, then month headers).
You start getting unreliable results (from screen readers) if you have row headers spread across several non-contiguous cells.
I'm assuming you don't want to use <table> and <th scope='row|col'>

Bootstrap 3 - background color for row, but not the whole row

I am using bootstrap in a fairly straightforward way, and I have a color specified in my row divs, e.g. which colors the entire row with the danger color, but on the desktop, I am only populating about 6 col-md's worth of data, and the extra color extending past where the actual data is displayed, looks funny.
On mobiles its fine, because the actual data is taking up the full row.
So, I want to be able to apply the background color to only col-md-8 of my rows when the web page is displayed on a desktop.
I tried adding the background to the individual cells, but since each of the cells is not a uniform height that didn't work either.
I tried specifying the row as being only col-md-8, but then that affects the size of all the other columns.
Do I just have to accept that I will have to change the md column sizes to take into account that they are now in a col-md-8 row?
Is there an easy to accomplish what I want?
Here is a sample of the code:
<div class="container">
<div class="row bg-danger">
<div class="col-md-3">.col-md-1</div>
<div class="col-md-2">.col-md-1</div>
<div class="col-md-1">.col-md-1</div>
<div class="col-md-1">.col-md-1</div>
</div>
There are only 7 columns of data, but the danger background is on the whole row.
Ah, now I see what you are after. Just take the target row and make it display:table; then you can get the equal height columns with display:table-cell;
jsFiddle here
.row {
display: table;
}
.row > div {
float: none;
display: table-cell;
}
Note: You can put this inside a media query if you only want the effect to happen at a certain screen size. (see this fiddle)
You could use your own CSS classes, to accomplish what you need.
Also, you could add the col-lg-6 class to the row.
Post your HTML code, otherwise it's really hard to help

How to increase padding between columns using Bootstrap 3.0

I am relatively new to programming and am making a website using bootstrap 3.0.
I want to make two rows that center in the middle of the page. For the first row I used div class="col-md-4 col-md-offset-2" and for the second row div class="col-md-4".
My first question is if it is ok that this adds up to 10 rows instead of 12 or if I need to specify the 2 rows on the right also? If so, how can this be done?
Also I would like to increase the horizontal spacing between the columns. I did a bit of research on that and came across mixins but its quit hard for me to grasp. If anybody here can provide me with a simple way to increase the horizontal spacing between two columns that would be great.
Thanks in advance.
looks like this is what you want
<div class="container">
<div class="row">
<div class="col-md-4 col-md-offset-2">col-md-4-offset</div>
<div class="col-md-4">col-md-4</div>
</div>
</div>
its perfectly fine to have column not add up to 12
here is a bootply
and if you want to pad your rows just add padding to .row class, by default there is no padding or margins between rows
Question 1: Yes, it's fine to leave dangling space after your columns, but good practice to tie it off by closing the .row after it.
Question 2: You can add margin to left and right of the column. But that throws off the offset column, so get around that by putting an empty .col-md-2 before them.
<div class="container">
<div class="row">
<div class="col-md-2"></div><!-- empty -->
<div class="col-md-4 margin">col-md-4</div>
<div class="col-md-4 margin">col-md-4</div>
</div>
</div>
CSS:
.margin {
margin-left:10px;
margin-right:10px;
}
Demo: http://www.bootply.com/OS6FX9sie8#
Also, you'll notice in my demo I put the custom class in a media-query. Do that if you want that margin adjustment to only apply on large screen devices, so the columns reach the screen edge on phones.

Bootstrap layout: 2 columns split 66/33% or 1 column 100% when the 2nd column hidden

I have a Bootstrap 3 layout like this
<div class="row">
<div class="col-md-8"></div>
<div class="col-md-4"></div>
</div>
Normally this displays the first column as 66% and the second column as 33%
When I have no content for the second column, I want to be able to hide it and make the first column take up 100% width. I think it can be done with a mixins but while I'm trying to get that working, is there a better way?
If it's empty you can add the class .col-md-12 after col-md-8 and add class .hide to the col-md-4. I don't know how you're implementing your site. If it's a CMS, you can have a little checkbox to add these classes if col-md-4 == empty.
If you're hiding at different breakpoints, look at the responsive utilities section of the TWB docs.
