I am a beginner in the area and I am not very knowledgeable, I have the following code, and I would like it to be filled in with numbers only and in the format "00/00/0000" and "00:00" respectively. I know there are other means, but I would like to know how to do this using only css. It's possible?
<input type="text" id="txtdia" size="4px" style="text-align:center" placeholder="Dia"/>
<input type="text" id="txthora" size="4px" style="text-align:center" placeholder="Hora"/>
