Change height of Slick Carousel - css

Here is a fiddle of Slick Carousel embedded in a Bootstrap thumbnail.
JSFiddle
How can I make the carousel only 200px tall and ensure that the images are scaled proportionally? I can't seem to get the carousel to fit inside a container who's height I dictate.
NOTE: Resize your browser after loading this fiddle! This works around a known bug where the plugin layout is not initializing on page load. This is not the issue I'm needing solved. Ignore this issue.

Answer:
CSS
.slick-slide {
height:200px;
}
.slick-slide img {
height:200px;
}

I was having to set the height eg .slick-carousel{width: 200px;} because adaptive height wasnt working and slick was making the carousel as tall as the imgs (before it was resized by css). but after messing around with it for a while. this is what works for me.
.slick-slide{
display: none;
float: left;
height: auto;
min-height: 1px;
img{
max-width: 100vw !important;
}
}

Try removing slidesToScroll from the config. The following simple combination worked for me without any additional CSS fudgery.
$('.slick-carousel').slick({
variableWidth: true,
centerMode: true
});

Set the container div's height to the desired height for example 60% and the slick's and the 2 following div's height to 100%.
EXAMPLE:
CSS:
.html {
height: 100%;
}
.slick-container {
height: 60%;
}
.slick-slider, .slick-list, .slick-track {
height: 100%;
}
JS:
$(document).ready(function(){
$('.slick-slider').slick();
});

I have faced the same problem more or less, using images in Slick is tricky. So when I had a webpage on desktop everything was very smooth. But on mobile the slide was to small. The suggestion with scale(2) did not work hence it would make the image bigger then te screen.
After going back and forward I decided, to crop the images to be more vertical instead of horizontal.
Then In Jquery I did:
if ($(window).width() < 820) {
$("#slide-1").prop("src", "/slide1-resp.png");
$("#slide-2").prop("src", "/slide2-resp.png");
$("#slide-3").prop("src", "/slide3-resp.png");
}
I hope this answer is relevant for those who came here with the same problem.

Apparently the issue with adaptive height it's a bug as the source code says:

DevExpress Web Dashboard in PiranhaCMS

I am currently working on a .NET Core application based on a CMS Framework named PiranhaCMS. This framework allows the definition of configurable "Blocks", basically widgets, that can be added by the users on their pages. The configuration page of the blocks is realized as a Vue.js component, and code is then compiled via gulp in a standard JS format (from the .vue file to the Vue.component(...) syntax) for the Piranha framework to read and render. The author of Piranha confirmed that this is the only way to define new blocks.
In one of our custom blocks, we are trying to implement a DevExpress Web Dashboard. I have tried following the steps outlined at https://docs.devexpress.com/Dashboard/401150/web-dashboard/dashboard-component-for-vue, but to no avail, since the compiler throws an Exception stating that the top-level declaration should be an export default { ... }, and not an import statement.
I came up with a workaround in which I dynamically load the required scripts and styles on the created() method of the component, and then define the dashboard in the same way I would in a classic javascript case (https://docs.devexpress.com/Dashboard/119158/web-dashboard/dashboard-control-for-javascript-applications-jquery-knockout-etc/add-web-dashboard-to-a-javascript-application);;) however, I am sure there is a more elegant solution to this problem.
Below is the code relevant to the problem. Here is the custom block itools-dashboard.vue:
<template>
<div class="form-group block-body">
<div :id="'dashboard-designer-' + uid" class="dashboard-designer">
<div :id="'dashboard_' + uid" style="height: 100%;">
</div>
</div>
<div class="row">
<div class="col-sm-6" style="padding:10px; margin-top: 0px;vertical-align: top;">
<fieldset>
<legend>Dashboard</legend>
<div class="form-group">
<label>Dashboard name</label>
<select class="form-control small" :id="'dashboard-names-' + uid" v-model="model.dashboardName.value">
<option v-for="dash in dashboardNames">{{ dash }}</option>
</select>
</div>
<div class="form-group">
<label>Update time</label>
<input class="form-control small" type="number" v-model="model.updateTime.value">
</div>
<div class="form-group">
<label>Width</label>
<input class="form-control small" type="text" v-model="model.width.value">
</div>
<div class="form-group">
<label>Height</label>
<input class="form-control small" type="text" v-model="model.height.value">
</div>

</div>
<div class="col-sm-6" style="padding:10px; margin-top: 0px; background-color: #fcfcfc; border:1px dotted lightgray; vertical-align: top;">

any kind of help is well appreciated
The gulpfile with the method “vueCompile” that you’re referring to was specifically written to suit the needs of the internal components we provide in the framework, it’s by no means a silver bullet for all Vue component compilation. However I understand your problem, before writing this code we desperately searched for existing npm-packages that would give us the functionality we needed, but this wasn’t that easy to find as we only use a subset of the features available in Vue.js
We’d be more than happy to get feedback or more information on how this could be done, so we’ll be watching this thread 👍🏼

How can I implement vertical scroll snapping with `IntersectionObserver`?

I am inspired by Rolls Royce website and want to implement the same scroll snapping feature in mine as well, I did it with the HTML default scroll-snap-type which gives me expected behavior but creates two scrollbars, one for the container and another one for the body, which is not expected so I tried to go with the IntersectionObserver but it causes an issue, I can travel to only adjacent slide when directly jumping from 1st slide to 3rd slide.
Here is the code sandbox link: https://codesandbox.io/s/scrollsnap-forked-pre0c?file=/pages/index.vue
Here is the code that I am working
<template>
<main class="landing">
<nav class="scroller">
<ul class="scroller__list">
<li
class="scroller__item"
v-for="(slide, index) in slides"
:key="index"
#click.prevent="scroll(slide.id)"
>
<a
class="scroller__dot"
:href="'#' + slide.id"
#click.prevent="scroll(slide.id)"
></a>
</li>
</ul>
</nav>
<div class="slides-container">
<slide
class="slide"
v-for="(slide, index) in slides"
:key="index"
:img="slide.img"
:id="slide.id"

alert(arrayOfNames[i]);
}
}
}}
Currently what I'm able to do it to show an alert with the names found in the page and which I'm trying to set a color to. My question is: How to set a specific color, visually visible on the screen to those elements.
Any manipulation is accepted including css/js injection, anything. I'm completly new to js and css and I'm sorry if something in the description doesn't make sense.

How to change CSS of columns - ReactTable

I am using react-table in my application.
I am stuck in doing one thing i.e. changing the CSS of columns while a column is being resized.
Currently when you resize a column only cursor changes. What I want is to add border to the selected column.
I searched for this on SO and google as well. But couldn't find anything useful. And In the documentation as well nothing is mentioned about this topic as well.
Update
Now I am able to add border while dragging the column while resizing. I am able to do so by adding and removing the class.
What I did to do so:
Created a var in the state for className:
this.state = {
addBorder: null
}
Passed this class name in my column:
const columns = [{
Header: 'Name',
accessor: 'name', // String-based value accessors!,
headerClassName: this.state.addBorder,
className: this.state.addBorder
}, {
Header: 'Age',
accessor: 'age',
Cell: props => <span className='number'>{2}</span> // Custom cell components!
}, {
id: 'friendName', // Required because our accessor is not a string
Header: 'Friend Name',
accessor: d => d.friend.name // Custom value accessors!
}, {
Header: props => <span>Friend Age</span>, // Custom header components!
accessor: 'friend.age'
}];
return (
<div onMouseUp={this.handleMouseUp}>
<ReactTable
data={data}
columns={columns}
resizable={true}
onResizedChange={(col, e) => {
const column = col[col.length-1];
this.setState({addBorder: column.id})
}} />
</div>
)
}
To remove the class when dragging ends:
handleMouseUp (e) {
this.setState({addBorder: null});
}
But I am still not able to add border on hover.
Now, I am sending my custom HTML in header props. And in my HTML I have made an extra div. And I have moved this div to right. And on hover of this div, I am emitting mouse events and changing CSS accordingly.
But Existing div in the header that is responsible for resizing column is overlapping with my Div.
Header: props => <div className='header-div'> Name <div onMouseOver = {() => {
console.log('mose');
this.setState({className: 'addBorder'});
}} className='hover-div' onMouseOut = {() => {console.log('sdasd');this.setState({className: null});}}> </div></div> ,
From what I understand, you want to add some border when you hover over a column header. If my understanding is correct, you can use :hover pseudo selector over the header class
.hdrCls:hover {
border: 2px solid rgba(0,0,0,0.6) !important;
}
Update :
You can manipulate state in onResizedChange handler exposed by react-table
onResizedChange={(newResized, event) => {
let resizedCol = newResized.slice(-1)[0].id;
if(this.state.activeCol !== resizedCol) {
this.setState({
activeCol: resizedCol,
resizing: true
})
}
}}
Also, make sure you have to make the resizing state to false on mouseup event. For that I have come up with the below solution.
componentDidUpdate(props, state) {
if (this.state.resizing && !state.resizing) {
document.addEventListener('mouseup', this.onMouseUp);
} else if (!this.state.resizing && state.resizing) {
document.removeEventListener('mouseup', this.onMouseUp);
}
}
onMouseUp = (evt) => {
this.setState({
activeCol: '',
resizing: false
});
evt.stopPropagation();
evt.preventDefault();
}
For reference:
const ReactTable = window.ReactTable.default
class App extends React.Component {
constructor(props) {
super(props)
this.state = {
activeCol: '',
resizing: false
}
}
componentDidUpdate(props, state) {
if (this.state.resizing && !state.resizing) {
document.addEventListener('mouseup', this.onMouseUp);
} else if (!this.state.resizing && state.resizing) {
document.removeEventListener('mouseup', this.onMouseUp);
}
}
onMouseUp = (evt) => {
this.setState({
activeCol: '',
resizing: false
});
evt.stopPropagation();
evt.preventDefault();
}
render() {
const data = [{
name:"Mark",
age:24
},
{
name:"Derek",
age:26
}]
const columns = [{
Header: 'Name',
accessor: 'name', // String-based value accessors!,
headerClassName: 'hdrCls',
className: (this.state.activeCol === 'name') && this.state.resizing ? 'borderCellCls' : 'defaultCellCls'
}, {
Header: 'Age',
accessor: 'age',
headerClassName: 'hdrCls',
className: (this.state.activeCol === 'age') && this.state.resizing ? 'borderCellCls' : 'defaultCellCls'
}];
return <ReactTable
data = { data }
columns = { columns }
showPagination= {false}
onResizedChange={(newResized, event) => {
let resizedCol = newResized.slice(-1)[0].id;
if(this.state.activeCol !== resizedCol) {
this.setState({
activeCol: resizedCol,
resizing: true
})
}
}}
/>
}
}
ReactDOM.render( < App / > , document.getElementById("app"))
.hdrCls:hover {
border: 2px solid rgba(0,0,0,0.6) !important;
}
.borderCellCls {
border-right: 2px solid rgba(0,0,0,0.6) !important;
border-left: 2px solid rgba(0,0,0,0.6) !important;
}
.defaultCellCls {
}

You can play around with CSS. Hope this is what you want and hope this helps.
Update:
I think you have to play with CSS to achieve what you desire.
.borderCellCls {
border-right: 2px solid rgba(0,0,0,0.6) !important;
border-left: 2px solid rgba(0,0,0,0.6) !important;
}
If you are here to find out how to set className to a column cell (with the react-table), here is the solution:
1)
<tr
{...row.getRowProps()}
>
{row.cells.map((cell) => (
<td
{...cell.getCellProps([
{
className: cell.column.className, // pay attention to this
style: cell.column.style,
// set here your other custom props
},
])}
>
{cell.render('Cell')}
</td>
))}
</tr>
2)
const columns = React.useMemo(
() => [
{
Header: 'Date',
accessor: 'date',
minWidth: 70,
className: 'text-dark fw-bolder fs-6 min-w-70px', // pass className props here
headerClassName: 'text-muted', // or another props like this one
}]
<Table columns={columns} ... />
And finally, those props will be passed to your cells
For TypeScript support follow the instructions in DefinitelyTyped, ie. create the file /src/types/react-table-config.d.ts with the content from the instructions, then add the following to it to support custom properties on your column (add more properties in the last line as required):
// Added to support classes to template from:
// https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/react-table
export interface ColumnInstance<
D extends Record<string, unknown> = Record<string, unknown>
> extends Omit<ColumnInterface<D>, 'id'>,
ColumnInterfaceBasedOnValue<D>,
UseTableColumnProps<D>,
Record<headerClassName | className, string> {}

Can't change height using AngularJS

I'm trying to change the height of a textarea using AngularJS within a directive. I add an attribute auto-resize to my textarea and have the directive defined as:
app.directive('autoResize',function(){
return {
restrict: 'A',
//scope: {},
replace: false,
link: function(scope, element, attrs) {
element.css({
'overflow': 'hidden',
'color': 'red',
'height': '50px'
});
}
}
}
The color and overflow styles are implemented onto the textarea, however the height of the text-area does not go to 50px.
Any help is appreciated.
This directive might do what you're looking for :)
Here is a codepen showing it working: https://codepen.io/benshope/pen/xOPvpm
app.directive('expandingTextarea', function () {
return {
restrict: 'A',
controller: function ($scope, $element, $attrs, $timeout) {
$element.css('min-height', '0');
$element.css('resize', 'none');
$element.css('overflow-y', 'hidden');
setHeight(0);
$timeout(setHeightToScrollHeight);
function setHeight(height) {
$element.css('height', height + 'px');
$element.css('max-height', height + 'px');
}
function setHeightToScrollHeight() {
setHeight(0);
var scrollHeight = angular.element($element)[0]
.scrollHeight;
if (scrollHeight !== undefined) {
setHeight(scrollHeight);
}
}
$scope.$watch(function () {
return angular.element($element)[0].value;
}, setHeightToScrollHeight);
}
};
});
you should set the rows attribute on a textarea rather than changing the height through css.
app.directive('autoResize',function(){
return {
restrict: 'A',
//scope: {},
replace: false,
link: function(scope, element, attrs) {
element.css({
'overflow': 'hidden',
'color': 'red'
});
element.attr("rows", 5);
}
}
}

You must to use 'style' for manipulation of css attributes at the DOM level instead 'css()'. You can use the '.css()' method when you are using jQuery. Try this in your directive.
element.style.height = '50px';
element.style.overflow = 'hidden';
element.style.color = 'red';
