I am using the element to upload image files to my hosted Blazor WASM site. The component renders a button with the words "Choose Files" on it.
I would like to replace this button with an image (or my own text, or anything else). I have tried using CSS to set a background image to the URL of an image I would want to use, and set the background-color of the button to "transparent", but this does not seem to change anything.
The source code for this component can be found here:
https://github.com/SteveSandersonMS/BlazorInputFile
I studied the code and found that this component is built using the standard Blazor input type.
<input type=file>
Steve shows a way to override the default functionality and style of the button using CSS.
Here is an example I created based on what I found:
<style>
.file-input-zone {
display: flex;
align-items: center;
justify-content: center;
background-color: blue;
color: white;
cursor: pointer;
position: relative;
width: 120px;
height: 30px;
}
.file-input-zone:hover {
background-color: lightblue;
}
.file-input-zone input[type=file] {
position: absolute;
width: 100%;
height: 100%;
opacity: 0;
cursor: pointer;
}
</style>
<div class="file-input-zone">
<InputFile />
Get me a file!
</div>
It will give you a button that looks like this:

I am using vue carousel and I want to change tge color of the pagination dots' borders. I don't know how and if it's even possible. I looked up the style of this buttons in dev tools and tried to rewrite the style. But nothing works
vue-carousel has two properties that control the color of the dots:
paginationColor - (default: #000000) The fill color of the active pagination dot. Any valid CSS color is accepted.
paginationActiveColor - (default: #efefef) The fill color of pagination dots. Any valid CSS color is accepted.
For example:
<carousel paginationColor="gray" paginationActiveColor="red">
demo
Try this in your global CSS
.v-carousel__controls__item{
color: #FFC400 !important;
}
There is a work-around that can give you full control over the dots and their appearance with pure CSS, using pseudo-elements. Make the existing dots transparent, and use ::after to create new dots that you can style as you like.
.VueCarousel-dot {
position: relative;
background-color: transparent !important;
&::after {
content: '';
width: 10px;
height: 10px;
border-radius: 100%;
border: 2px solid black;
background-color: gray;
position: absolute;
top: 10px;
left: 10px;
}
&--active::after {
background-color: red;
}
}
This is not an ideal solution, however the provided options for styling dots in Vue Carousel are quite limited, and if you have a strict style guide to follow, this solution can give you the control you need.
I'm using iViewUI for my Tag component, but I wanted to customize its size and where the "X" close button is.
I was able to change the width by simply adding a class to the Tag, but for some reason, even i'm trying to override also its children icon, is not responding to the change at all, is not applying it. Checked on browser, not adding it there either.
This is what I've done so far:
<Tag class="Badge-tag" color="warning" closable #on-close="removeTag">{{ badge }}</Tag>
Then on the less file I added the following:
.Badge-tag {
width: 60px;
position: relative;
.ivu-icon.ivu-icon-ios-close {
position: absolute;
right: 2px;
top: 4px;
}
}
I had no luck at all. I don't know why is not setting it.
If you put above css as global css, I think it should work.
I create a demo on jsfiddle here, please check
If you use scoped css, you can try using deep selector
.Badge-tag {
width: 60px;
position: relative;
/deep/ .ivu-icon.ivu-icon-ios-close {
position: absolute;
right: 2px;
top: 4px;
}
}

On a desktop screen it's fine, but on a mobile device, the site title and description do not budge. I added some custom CSS to allow the logo to display beside the site title - here is what I entered:
#logo .site-title, #logo .site-description {
display: block !important;
}
.site-title {margin-top: 26px;}
#logo img {
float: left;
margin-right: 20px;
}
#logo {
float: left;
width: 800px;
}
And for the image on the right side of header, I entered this:
.header-widget {
float: right;
width: 200px;
margin-top: 10px;
}
It's not looking good on my iPhone and I'm unsure what to do. If anyone can suggest a fix, that would be greatly appreciated!
try and deactvate or override existing css . There are #media queries in your existing css

Any suggestion is important

You just need to override the dijitTextBox CSS class.
You might need to use CSS specificity to make sure that the CSS is picked up (instead of using !important).
Here's a simple example:
.dijitTextBox {
width: 40px;
height: 8px;
}
As you are using Bootstrap theme you need to adjust the arrow button too.
This works for me:
.dbootstrap .dijitTextBox {
height: 24px;
}
.dbootstrap .dijitComboBox .dijitButtonNode.dijitArrowButton {
height: 22px;
}
.xsp.dbootstrap .dijitInputContainer {
padding-top: 0px;
}
.dbootstrap .dijitComboBox input.dijitArrowButtonInner {
margin-top: -3px;
margin-left: -5px;
}
.dbootstrap .dijitMenuItem {
padding: 0px 10px;
}
I have a web site with a regular <input type="file"> file upload, POSTing the data to the backend when the form is submitted.
I would like to progressively enhance the form so that you can drop a file from outside the browser anywhere in the viewport (not just on the file input field, as built into some browsers) to upload it.
Whether or not the form autosubmits isn't important. So if the drag-and-drop only selects the file in the file field, without starting an upload, that's fine. I don't need support for multiple files. I don't need to show upload progress, thumbnails or anything fancy.
I know there are JS libs that support drag-and-drop uploads, but they all seem to upload via AJAX. I could do that, but then I would need to modify the backend and frontend to handle upload errors, redirect and show the right messages on success and so on.
I want a progressive enhancement that doesn't require any backend changes. It should happen synchronously using the form in the page. JS is fine, as long as the upload happens "in the foreground". Synchronous AJAX would not work, of course.
Although not really "synchronous" (JavaScript execution won't actually halt), you can set the files selected by <input type="file"> programatically. In fact, such elements and dragging share their file backend implementation (File and FileList instances), so it's really straight-forward. What's more, due to both frontends using FileLists, dragging multiple files work just as seamlessly.
This works in Chrome (using jQuery): http://jsfiddle.net/qMmPr/.
$(document).on("dragover drop", function(e) {
e.preventDefault(); // allow dropping and don't navigate to file on drop
}).on("drop", function(e) {
$("input[type='file']")
.prop("files", e.originalEvent.dataTransfer.files) // put files into element
.closest("form")
.submit(); // autosubmit as well
});
Thanks to #pimvdb comment, I came up with a pretty elegant solution.
Since drag and dropping on the <input type="file" /> works, why not making it full-screen on dragstart to make sure the user can't miss it? Anyway he is dragging so his intentions are clear at this moment.
Here's a demo: https://jsfiddle.net/08wbo4um
NB: unfortunately this doesn't seem to work in an iframe, but it does work on an actual page. You can still apprehend the behavior.
Here's the snippet:
$('input[type="file"]').on('change', function(e){
var fileName = e.target.files[0].name;
if (fileName) {
$(e.target).parent().attr('data-message', fileName);
}
});
$(document).on('drag dragstart dragend dragover dragenter dragleave drop', function(e) {
if ($('input[type="file"]').length) {
if (['dragover', 'dragenter'].indexOf(e.type) > -1) {
if (window.dragTimeout)
clearTimeout(window.dragTimeout);
$('body').addClass('dragged');
} else if (['dragleave', 'drop'].indexOf(e.type) > -1) {
// Without the timeout, some dragleave events are triggered
// when the :after appears, making it blink...
window.dragTimeout = setTimeout(function() {
$('body').removeClass('dragged');
}, 100);
}
}
});

<h3>Drag N Drop file upload without AJAX Demo</h3>
<p>Try drag and dropping a file. :-)</p>
<div class="form-group file-upload" required="required">
<label class="cols-sm-2 control-label" for="document_file">File Upload</label><br>
<div class="cols-sm-10">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-file" aria-hidden="true"></i></span>
<div class="form-control" data-message="Click to select file or drag n drop it here">
<input required="required" title="Click to select file or drag n drop it here" type="file" name="document[file]" id="document_file">
</div>

</div>
It can be done by turning autoUpload to false, collecting the files in an array, then on form submit do a single ajax call with all the files together with the form data, as described here.
