#StackBounty: #javascript #html #css #reactjs #react-day-picker React date picker month / year selection doesn't work on iOS Safari…

Bounty: 50

I am using react-day-picker package to select a date with the year/month props included. However, the year/month dropdown doesn’t work properly on iOS mobile browsers:

import React from 'react';
import ReactDOM from "react-dom";
import DayPickerInput from 'react-day-picker/DayPickerInput';
import 'react-day-picker/lib/style.css';

const currentYear = new Date().getFullYear();
const fromMonth = new Date(currentYear, 0);
const toMonth = new Date(currentYear + 10, 11);

function YearMonthForm({ date, localeUtils, onChange }) {
  const months = localeUtils.getMonths();

  const years = [];
  for (let i = fromMonth.getFullYear(); i <= toMonth.getFullYear(); i += 1) {

  const handleChange = function handleChange(e) {
    const { year, month } = e.target.form;
    onChange(new Date(year.value, month.value));

  return (
    <form className="DayPicker-Caption">
      <select name="month" onChange={handleChange} value={date.getMonth()}>
        {months.map((month, i) => (
          <option key={month} value={i}>
      <select name="year" onChange={handleChange} value={date.getFullYear()}>
        {years.map(year => (
          <option key={year} value={year}>

export default class Example extends React.Component {
  constructor(props) {
    this.handleYearMonthChange = this.handleYearMonthChange.bind(this);
    this.state = {
      month: fromMonth,
  handleYearMonthChange(month) {
    this.setState({ month });
  render() {
    const dayPickerProps = {
      month: this.state.month,
      fromMonth: fromMonth,
      toMonth: toMonth,
      captionElement: ({ date, localeUtils }) => (

    return (
); } } ReactDOM.render(<Example />, document.getElementById("root"));

#StackBounty: #html #gui #user-interface #rest #gui-builder Simple Web UI builder for backend devs

Bounty: 50

I’m a backend dev who technically knows how to work with html css js… but hates it. Is there a low-code free or OSS tool where I can quickly build or prototype simple web guis for my backend services? Functionality should be something like drag and drop UI components like buttons and form fields, sending rest requests and parsing the JSON or XML responses and displaying them or part of them in tables or lists or generating lists of links based on responses from my services. Doesn’t need to be fancy at all, a plain unstyled html look would work just fine as long as the amount of html/css/js that needs to be written is minimized.

#StackBounty: #html #css #internet-explorer Fixing IE11's image rescale bug?

Bounty: 50

As a little experiment, I am trying to fix the wrongly rescaled images one gets when opening the snopes.com homepage using IE11. (See screenshot)

Snopes homepage

Just to clarify, I am not the owner of the website.

I can see that the affected images belong to a class named “bg-image”, but as a beginner, I have almost no idea where to go from there.

Can anyone suggest a quick’n’dirty fix that I can just try out from IE’s devtools console?

#StackBounty: #jquery #html #css #animation #dom jQuery Slideshow with pagination

Bounty: 50

The code below is for a slideshow that shows an .active slide, pre-loads a .next slide, and holds the .last slide in the background.

My big issue with this is there seems to be duplication and probably very inefficient code here that I would like to improve upon, but do not yet have that complete knowledge.

I am not looking for the code rewritten, but would like to hear of ideas that can improve not only my knwoledge of jQuery but also the effiency of the code.


div class=”snippet” data-lang=”js” data-hide=”false” data-console=”true” data-babel=”false”>

$(document).ready(function() {

  $('.slide:first').addClass('active').delay($duration).queue(function() {


// Globals
var $classes = 'last active show-text next';
var $duration = 1250;

// Function for the pagination operation
$('.dot').on('click', function() { // the dot click

  var $This = $(this);
  // Match the index to the slide numbers
  var GetIndex = $This.closest('li').index() + 1;



  // Show new active slide
  $('#slide' + GetIndex).addClass('active').delay($duration).queue(function() {
  // Add class to previous slide
  $('.slide').eq(($('.slide.active').index() - 1) % $('.slide').length).addClass('last');
  // Add class to next slide
  $('.slide').eq(($('.slide.active').index() + 1) % $('.slide').length).addClass('next');


$('.button').click(function moveSlide() {

  // Variables for moving slide
  var $active = $('.slide.active');
  var $prevSlide = $('.slide').eq(($active.index() - 1) % $('.slide').length);
  var $afterPrevSlide = $('.slide').eq(($active.index() - 2) % $('.slide').length);
  var $nextSlide = $('.slide').eq(($active.index() + 1) % $('.slide').length);
  var $slideAfterNext = $('.slide').eq(($active.index() + 2) % $('.slide').length);

  // Variables for pagination
  var $tagNextDot = $('#' + $prevSlide.attr('id') + 'Dot');
  var $tagPrevDot = $('#' + $nextSlide.attr('id') + 'Dot');


  if ($(this).is("#prev")) {

    $prevSlide.addClass('active').delay($duration).queue(function() {

  } else {
    $nextSlide.addClass('active').delay($duration).queue(function() {
