vertical align placeholder in ie

can someone help me to fix the vertical align of the placeholders in IE for the below markup? I fixed on other browsers and looks good with transform: translateY(3px); unfortunatly the html is from a widget of my newsletters provider so I cannot change it, I only have access to css style.

If possibile I would like the checkbox to look the same in IE too, it looks like the -webkit-appearance: none; doesn't works on ie. many thanks

HTML

<input type="hidden" name="wpmailup-subscribe" class="wpmailup-subscribe" value="subscribe">
<fieldset class="subscribeDataTable">
  <h4 class="widgettitle">Iscriviti alla nostra newsletter!</h4>
  <p class="muDescription"></p>
  <p class="muField">
     <input type="text" name="sub-email" class="sub-email" placeholder="Email*">
  </p>
  <p class="muField">
     <input type="text" name="sub-ext1" class="sub-ext1" maxlength="80" placeholder="Nome*">
  </p>
  <p class="muTermsCheckbox">
     <label><input name="terms-confirm" class="terms-confirm" type="checkbox" value="yes"> Accetto l'informativa sulla <a class="ppaccept" href="/privacy-policy"></a></label>
  </p>
  </span>
  <p class="muSubmit"><input type="submit" name="submit" value="iscriviti!"></p>
</fieldset>

CSS

.subscribeForm input {
  border-width: 1px;
  border-style: solid;
  border-color: #ffd300;
  padding: 16px;
  line-height: 2em;
  font-size: 16px;
}

Solution

You have line-height: 2em; set on the input, this calculates differently in different browsers. Remove this line and you should see the placeholder vertically aligned on both IE and Chrome/other modern browsers.

.subscribeForm input {
  border-width: 1px;
  border-style: solid;
  border-color: #ffd300;
  padding: 16px;
  /* line-height: 2em; */
}

EDIT:

Regarding the appearance issue, -webkit-appearance is a vendor prefix.

By switching the code to:

input {
    -webkit-appearance: none;
    -moz-appearance: none;
    appearance: none;
}

This will ensure it is applied to all browsers. NOte that Edge and IE handle prefixing differently.
