Applying HTML style to inputs

[mbel13131]

I would like to apply the custom style to a set of inputs. How do I correctly write this code? 

I'm aware of the option to create one style clause for each input ID but this seems ridiculous and the wrong way to do it for, say, 20 inputs.

Cheers.

<form version="1.1" theme="light">
  <fieldset submitButton="false">
  </fieldset>
    <row>
      <panel>
      <html>
        <style>
          #LineByLine {
            display:flex !important;
            padding-right: 10px;
            padding-top: 5px;
          }
        </style>
      </html>
    </panel>
    </row>
  <row>
    <panel>
      <input id="input1" type="text" token="1">
        <label>1</label>
      </input>
    </panel>
    <panel>
      <input id="input2" type="text" token="2">
        <label>2</label>
      </input>
    </panel>
  </row>
</form>

Never mind, this is a basic question I answered myself by learning about HTML in general (apply style to the div/container wrapped around the input, if someone's looking for this basic answer).

(just to add though, I can't figure out how to have html style apply to standard child-of-form Splunk input objects)
