# --description--
|
||
|
|
||
|
Bootstrap uses a responsive 12-column grid system, which makes it easy to put elements into rows and specify each element's relative width. Most of Bootstrap's classes can be applied to a `div` element.
|
||
|
|
||
|
Bootstrap has different column width attributes that it uses depending on how wide the user's screen is. For example, phones have narrow screens, and laptops have wider screens.
|
||
|
|
||
|
Take for example Bootstrap's `col-md-*` class. Here, `md` means medium, and `*` is a number specifying how many columns wide the element should be. In this case, the column width of an element on a medium-sized screen, such as a laptop, is being specified.
|
||
|
|
||
|
In the Cat Photo App that we're building, we'll use `col-xs-*`, where `xs` means extra small (like an extra-small mobile phone screen), and `*` is the number of columns specifying how many columns wide the element should be.
|
||
|
|
||
|
Put the `Like`, `Info` and `Delete` buttons side-by-side by nesting all three of them within one `<div class="row">` element, then each of them within a `<div class="col-xs-4">` element.
|
||
|
|
||
|
The `row` class is applied to a `div`, and the buttons themselves can be nested within it.
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
Your buttons should all be nested within the same `div` element with the class `row`.
|
||
|
|
||
|
```js
|
||
|
assert($('div.row:has(button)').length > 0);
|
||
|
```
|
||
|
|
||
|
Each of your Bootstrap buttons should be nested within its own `div` element with the class `col-xs-4`.
|
||
|
|
||
|
```js
|
||
|
assert($('div.col-xs-4:has(button)').length > 2);
|
||
|
```
|
||
|
|
||
|
Each of your `button` elements should have a closing tag.
|
||
|
|
||
|
```js
|
||
|
assert(
|
||
|
code.match(/<\/button>/g) &&
|
||
|
code.match(/<button/g) &&
|
||
|
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
||
|
);
|
||
|
```
|
||
|
|
||
|
Each of your `div` elements should have a closing tag.
|
||
|
|
||
|
```js
|
||
|
assert(
|
||
|
code.match(/<\/div>/g) &&
|
||
|
code.match(/<div/g) &&
|
||
|
code.match(/<\/div>/g).length === code.match(/<div/g).length
|
||
|
);
|
||
|
```
