Custom styled input type file upload button with pure CSS

In this guide I’ll show you how to create a stylish and user friendly file upload button with pure CSS and HTML.

Markup

To upload files you’ll need to use the input tag with type=»file» attribute. Additionally you can specify which file types you’re allowing to upload via accept attribute.

This markup produces a button with a Choose file title followed by a text which indicates the file name when selected. By default it is No file chosen.

Input with type file default look differs on different browsers:

Styling

The upload file widget structure consists of a block that displays a button and a file name. A user can click anywhere inside the block or drag a file from the desktop and it will open up the upload window.

Styling the upload file block

If you apply styles for the input[type=file] selector it will set them for the whole widget block, that is the button and text.

input[type=file]  width: 350px; max-width: 100%; color: #444; padding: 5px; background: #fff; border-radius: 10px; border: 1px solid #555; > 

The result already looks much better as it indicates the zone where user is able to click or drag the file.

Styling the upload file button

By default, the Choose file button has a plain user-agent style. To style the button with CSS you should use the ::file-selector-button pseudo-element to select it. It is supported in all modern browsers.

input[type=file]::file-selector-button  margin-right: 20px; border: none; background: #084cdf; padding: 10px 20px; border-radius: 10px; color: #fff; cursor: pointer; transition: background .2s ease-in-out; > input[type=file]::file-selector-button:hover  background: #0d45a5; > 

Styling the the click/drop zone

If you wich to go a bit further, you can create a large zone where user can click and drag files. This large zone will make it easier for people to use the widget, as it don’t require to be that precise when dragging a file, especially on smaller screens.

To implement a large drop zone, you’ll need to wrap your file upload input into a label tag and specify a description text that will let users know how to use the widget.

 for="images" class="drop-container" id="dropcontainer">  class="drop-title">Drop files here or  type="file" id="images" accept="image/*" required>  

For the layout, we need to set display to flex with flex related properties for positioning. The height and padding properties for proportion. And finally add some fancy styles like border and hover effects to highlight the file upload zone and you’re ready to go.

.drop-container  position: relative; display: flex; gap: 10px; flex-direction: column; justify-content: center; align-items: center; height: 200px; padding: 20px; border-radius: 10px; border: 2px dashed #555; color: #444; cursor: pointer; transition: background .2s ease-in-out, border .2s ease-in-out; > .drop-container:hover  background: #eee; border-color: #111; > .drop-container:hover .drop-title  color: #222; > .drop-title  color: #444; font-size: 20px; font-weight: bold; text-align: center; transition: color .2s ease-in-out; > 

Handling drag and drop events

Additionally, you can handle cases when the user will try to drag the file over the drop area. CSS alone cannot handle such cases, so we can add a little bit of JavaScript.

There are two points to consider to improve UX for the drop field:

1. Indicate the drop area when the user is dragging a file over it
2. Make it possible to drop a file inside the drop area, and not just the input element

To indicate drop area when user is dragging a file over it, we’ll need to use the dragenter and dragleave events. Both on the label tag, since it represents the drop area. For each event we add or remove a CSS class accordingly.

Since user will be dropping to the label tag we also need to set the input value with the file. To do that we need to do 2 things:

1. Set dragover event for the label tag, set e.preventDefault() and pass false as the third parameter for the addEventListener method
2. On drop event, we need to set the input’s files property to the file via fileInput.files = e.dataTransfer.files

 const dropContainer = document.getElementById("dropcontainer") const fileInput = document.getElementById("images") dropContainer.addEventListener("dragover", (e) =>  // prevent default to allow drop e.preventDefault() >, false) dropContainer.addEventListener("dragenter", () =>  dropContainer.classList.add("drag-active") >) dropContainer.addEventListener("dragleave", () =>  dropContainer.classList.remove("drag-active") >) dropContainer.addEventListener("drop", (e) =>  e.preventDefault() dropContainer.classList.remove("drag-active") fileInput.files = e.dataTransfer.files >) 

As for styles, we can use similar styles to :hover state, but this time with a designated class:

.drop-container.drag-active  background: #eee; border-color: #111; > .drop-container.drag-active .drop-title  color: #222; >

Styling file inputs like a boss

HTML elements have default styles applied to them by individual browsers. These styles could vary depending on the browser, and applying your own custom styles could range from being very easy to unnecessarily complicated (sometimes impossible). In this article we would be going through how to style file inputs, which happens to be one of those difficult elements to style using CSS. If you’ve worked with file inputs in your application, you’d know that the default style doesn’t look so nice. Here’s an example of how it looks in chrome and firefox in case you’re wondering. The good news is, we can fix this. the bad news is we won’t be able to use the «conventional» method.

Styling File Inputs

 class="file-input">  type="file" id="file" class="file">  for="file">Select file  

Hiding the input

.file  opacity: 0; width: 0.1px; height: 0.1px; position: absolute; > 

You might be thinking, why not use display: none to hide the input. Well the problem with that is the input field would be removed from the layout and then become inaccessible to people using screen readers which would be very bad. Another important thing to note is the label . With file inputs, clicking on the label also opens up the file picker, so we can use that to our advantage and style the label anyway we want.

Styling the label

Now that we’ve hidden the default input, we can decide to style the label however we want. For simplicity sake, let’s just make it look like a button.

.file-input label  display: block; position: relative; width: 200px; height: 50px; border-radius: 25px; background: linear-gradient(40deg, #ff6ec4, #7873f5); box-shadow: 0 4px 7px rgba(0, 0, 0, 0.4); display: flex; align-items: center; justify-content: center; color: #fff; font-weight: bold; cursor: pointer; transition: transform .2s ease-out; > 

Accessibility

So we’ve been able to style the label to look like a button, but that’s not all. We need to add some sort of indications to the label for when people hover on the field, or try to focus on the file field using the keyboard. I’m just going to do something simple here and increase the size of the label when that happens.

input:hover + label, input:focus + label  transform: scale(1.02); > 

input:focus + label  outline: 1px solid #000; outline: -webkit-focus-ring-color auto 2px; > 

The -webkit-focus-ring-color is used to get the default outline look on webkit browsers like chrome or safari. For non webkit browsers, a black outline would be applied to the element.

Javascript Enhancements

We can use JavaScript to display the name and size of the file selected. This would create a slightly more natural feel to the custom field. So let’s modify our HTML and CSS a bit.

 class="file-input">  type="file" id="file" class="file">  for="file"> Select file  class="file-name">
   

.file-name  position: absolute; bottom: -35px; left: 10px; font-size: 0.85rem; color: #555; > 

Finally, we would add an event listener to the file input and reflect the name and size of the file below the label.

const file = document.querySelector('#file'); file.addEventListener('change', (e) =>  // Get the selected file const [file] = e.target.files; // Get the file name and size const  name: fileName, size > = file; // Convert size in bytes to kilo bytes const fileSize = (size / 1000).toFixed(2); // Set the text content const fileNameAndSize = `$fileName> - $fileSize>KB`; document.querySelector('.file-name').textContent = fileNameAndSize; >); 

Here’s how everything looks.
And that’s it for the file input. You could decide to style this however you want to get the behavior you want, it’s up to you. Happy styling!😁😁

Произвольный вид поля file в html-форме, одинаковый во всех браузерах

Не смотря на развитие, внедрение новых стандартов и плюшек в браузерах, у нет единых стандартов, как отображать элемент/> по умолчанию. Более того, у этого элемента нет атрибутов, позволяющих его в какой-то мере стилизовать.
Из-за необходимости привести это поле формы к единому виду во всех браузерах и «вписать» в разработанный дизайн, после поисков и анализа материалов в интернете был разработан метод замены вида поля формы на html+css, и js для расширения функциональности.

Как по умолчанию выглядит это поле?

Так он выглядит в Internet Explorer 9:

А так — в Firefox:

В Google Chrome:

В Opera:

В Safari:

Стилизация поля file

.fileform < background-color: #FFFFFF; border: 1px solid #CCCCCC; border-radius: 2px; cursor: pointer; height: 26px; overflow: hidden; padding: 2px; position: relative; text-align: left; vertical-align: middle; width: 230px; >.fileform .selectbutton < background-color: #A2A3A3; border: 1px solid #939494; border-radius: 2px; color: #FFFFFF; float: right; font-size: 16px; height: 20px; line-height: 20px; overflow: hidden; padding: 2px 6px; text-align: center; vertical-align: middle; width: 50px; >.fileform #upload

Теперь во всех браузерах поле формы выглядит одинаково, при этом форма выбора файла всё так же появляется по клику и на поле и на кнопку:

Главный недостаток полученного решения от стандартной формы — оно никак визуально не сигнализирует о том, что файл был выбран. Эта проблема решается с использованием javascript.

Добавление подписи о выбранном файле

Добавим к полю функцию-обработчик событий, а к блоку — еще один блок-заголовок и, конечно, его стиль:

Сама функция-обработчик получает полное имя выбранного файла, отбрасывает путь (с проверкойдля разных файловых систем), сохраняет имя с расширением в переменную filename и записывает его в блок fileformlabel.

function getName (str) < if (str.lastIndexOf('\\'))< var i = str.lastIndexOf('\\')+1; >else < var i = str.lastIndexOf('/')+1; >var filename = str.slice(i); var uploaded = document.getElementById("fileformlabel"); uploaded.innerHTML = filename; > 

Теперь поле формы выглядит так (при этом можно менять его размер, цвет, шрифт и выравнивание):

Данная заметка — реализация метода, предложенного в статье «Кастомизация input type=”file” с помощью CSS»
