I'm trying to implement a custom template to allow for selection of image(s) to upload. After the user selects an image this is shown in a horizontal scroller on the form. The model field is an array of image filenames selected.
The functionality works perfectly in a normal form, but when converted into Angular-Formly, the image selection process works, the model field (array) gets updated, but the NG-REPEAT (horizontal scroller) does not show the images in the array.
The template I'm trying to make work is:
<!-- IMAGE HORIZONTAL SCROLLER AND INPUT -->
<script type="text/ng-template" id="imagePicker.html">
<ion-item class="item-icon-right">
<i class="icon ion-images" ng-click="to.onclick(model,options)"></i>
<ion-scroll direction="x" style="height:200px; min-height: 200px; overflow: scroll; white-space: nowrap;">
<img ng-repeat="image in model[options.key]" ng-src="{{urlForImage(image)}}" style="height:100px; padding: 5px 5px 5px 5px;"/>
</ion-scroll>
</ion-item>
</script>
<!-- END OF IMAGE HORIZONTAL SCROLLER AND INPUT -->
I solved this myself. The problem was
ng-src="{{urlForImage(image)}}"
For some reason the call does not get through. So I call this while storing the value in the array and changed it to
ng-src="{{ image }}"
Now it works.

My goal is to use ag-grid in an Angular 5 project and have the grid take up all of the available vertical space in a flexbox layout. The grid seems happy to use "height:100%" when it's contained in a div which has a defined pixel height or when the div has a percentage height but isn't in a flexbox layout. But it always seems to have no height when I try to host it in a flex item.
How can I get my grid to expand to take up the height of its flex item container? Here's a plunker with an example of what I'm seeing and trying: https://embed.plnkr.co/D8YgM6/.
Here's how I am creating my layout:
<div style="height:100%;display:flex;flex-direction:column;">
<div style="height:250px;flex-grow:0;">
<h5>Container div with specified height in pixels, ag-grid with percentage height</h5>
<ag-grid-angular style="width: 100%; height: 80%" class="ag-theme-balham"
[columnDefs]="columnDefs"
[rowData]="rowData"
>
</ag-grid-angular>
</div>
<div style="flex-grow:1;">
<h5 class="red">Container div using flex height, ag-grid with percentage height</h5>
<p>How can I get the grid to be aware of my div's actual height?</p>
<ag-grid-angular style="width: 100%; height: 80%;" class="ag-theme-balham"
[columnDefs]="columnDefs"
[rowData]="rowData"
>
</ag-grid-angular>
</div>
</div>
I want the grid in the second flex item to have an appropriate height. How can I do this?
In your plunker, set the flex-basis of the item containing your grid to 0, this achieves I think what you are after. I've just been wrestling with the same:
.item-1 {
flex-grow: 1;
flex-shrink: 0;
flex-basis: 0;
}

I'm not sure why this works, maybe someone with more in depth knowledge of ag-grid can comment?
try setting auto height on grid ready event
this.gridApi.setDomLayout('autoHeight');

Is there a way to manipulate text in document.write code? I'm currently doing this
if (score > 35) {document.write(output); document.write('<img src="images/Rabbit.jpg">')}
to print the output of the users choices, but you get a huge image and this tiny little text. Can someone at least point me to some information on how to, or (if even possible) the code to edit it in CSS?
Forgot to add that (output) outputs predefined text. That would probably help
Just add this inline CSS to the image tag:
<img src="images/Rabbit.jpg" style="width: 200px; height: 200px;">
If you can't change the HTML outputted then add this internal CSS in your HTML head.
<head>
<style>img { width: 200px, height: 200px; } </style>
</head>
I've tried to insert a <br /> tag to break the line after fontello icon and found that it's impossible when div is styled with "display:flex". Adding white space is also disabled. Adding new lines after some character is possible, but new line starts beneath <i> tag. Why and how to fix that?
PS: I've noticed that in Chrome situation is better than in Firefox, but new line still starts beneath <i> tag.
Example:
.with_flexbox{
display:flex;
color:purple;
}
<div class="with_flexbox red">
With flexbox I can't use <br /> tag right after <i><i></i><br /> tag
</div>
<div class="without_flexbox">
Without flexbox break after <i><i></i><br />
tag works fine.
</div>
<div class="with_flexbox">
White space is also disabled right after <i><i></i> tag. <br />And why this new line starts beneath <i> tag?
</div>
In your third example contents of your flex container are split by <i> node into 3 flex items, you get 1 item that consists of:
White space is also disabled right after, second item <i><i></i> and third item tag. <br> And why this new line starts beneath <i> tag?. Everything looks fine, you get 3 nodes displayed horizontaly, there is a line break after word tag, just as you wrote it.
Wrapping text fragments into separate tags not only makes sense semantically but also helps you maintain your code.
If you want to stick to flexbox, you should name each node separately and use flex-direction: column instead of br tags, or you could set flex basis for both elements and use flex-wrap. Example snippet attached below.
.item {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
outline: 1px solid red;
}
.item__icon {
outline: 1px solid blue;
}
.item__intro {
outline: 1px solid green;
}
.item__description{
outline: 1px solid yellow;
}
<figure class="item">
<p class="item__intro">White space is also disabled right after</p>
<i class="item__icon"><i></i>
<figcaption class="item__description">tag. <br />And why this new line starts beneath <i> tag?</figcaption>
</div>
In the image below, you can see i have two tabs help and Instructions, i want to place these two tabs next to each other where the Help tab currently is. When i use the margin-left: property, only the help button moves to the left and the instructions button stays in the same place.
The css i am using to configure this:
.v-csslayout-topbarapplicant .v-button,
.v-csslayout-topbarapplicant .v-nativebutton,
.v-csslayout-topbarapplicant-invert .v-button,
.v-csslayout-topbarapplicant-invert .v-nativebutton {
float: right;
display: inline;
margin-right:0px;
margin-left: 268px;
margin-top: -18px;
padding: 0 3px 2px 0;
line-height: 11px;
}
How can i change the spacing so that both tabs (vaadin components) move together?
You need to make sure both items are wrapped with a div. Then you set the margin-left to that div, not only one of the items.
There's no way of telling in the CSS that you posted which items are being manipulated. If both of these items, "help" and "Instructions", are in the CSS you posted, then you to need to change it so that both items exist as one, meaning in one div. If only one of these items exist in your CSS that you posted, then you have only one of them being manipulated with the CSS, and that one is floating right. Ensure both items are floated in the same direction and they are wrapped. Apply the margin to this wrapper div.
The general structure should look like this:
CSS:
#help, #instructions {
float: right;
}
div#wrapper {
margin-left: 268px;
] /* wrapper containing both items, "help" and "Instructions" */
HTML:
<div id="wrapper">
<div id="help"></div>
<div id="instructions"></div>
</div>
I think that you are having some inheritance problems.
I would suggest first checking what inheritance this property is following, and if you still have problems I would then create separate divs for Help and Instructions, where instructions has a different right margin. I hope this helps! This type of problems are stubborn.
i want to center align an image of 18px height with text next to it. Here is the code i use:
<div style="line-height:18px; font-size:12px;">
<img src="somepic.jpg" style="height:18px; vertical-align:middle;">Some text here
</div>
With that code, the div container is rendered with a height of 19px instead of 18px and text isn't centered with image. I tried on Safari 4 and Firefox 3.6. What is the reason for that 1 px?
Thanks
Don't forget to reset styles
(margin/padding) : div, img, span {
margin:0; padding:0; border:0 }
For vertical-align to work, your
elements must me inline.
A classic choice to align text
vertically is to give a line-height
equal to container.
For example :
<div><img src="somepic.jpg" style="height:18px; vertical-align:middle;"><span style="line-height:18px;">Some text here</span></div>
Maybe you have a border somewhere in there you need to get rid of or set to zero width?
i'm not totally sure I understand what the problem is here but if its just that the image is a few pixels from where you would like it to be, then why don't you just position the image relatively. for example:
<div style="line-height:18px; font-size:12px;">
<img src="somepic.jpg" style="height:18px; vertical-align:middle; position: relative; bottom: 2px;">Some text here
</div>
this will shift the image up by 2px from where it originally was.
