This situation may seem confusing to many, as it certainly does to me.
I am currently working on developing a login page where the credentials are positioned at the center of the page both horizontally and vertically.
I have successfully achieved this layout but along the way, I encountered something perplexing that I couldn't quite comprehend.
Below is my HTML code snippet:
<div class="LoginWrapper">
<div class="Login">
<div id="Username" title="Register Number">
<asp:Label ID="UsernameLabel" runat="server" Text="Username" AssociatedControlID="UserNameTextBox"></asp:Label>
<asp:TextBox ID="UserNameTextBox" runat="server" CssClass="LoginTextBox"></asp:TextBox>
</div>
<div id="Password" title="Password">
<asp:Label ID="PasswordLabel" runat="server" Text="Password" AssociatedControlID="PasswordTextBox"></asp:Label>
<asp:TextBox ID="PasswordTextBox" TextMode="Password" runat="server"></asp:TextBox>
</div>
<div><asp:Button ID="Button1" runat="server" Text="Login" />
</div>
</div>
And here are my CSS classes responsible for aligning the elements:
.LoginWrapper {
width:1%; //This part seems unconventional
height:500px;
display:table-cell;
text-align:center;
vertical-align:middle;
}
.Login {
width:300px;
height:auto;
margin:10px;
padding:20px;
display:inline-block;
text-align:center
}
One peculiar aspect is the width set to 1% in the LoginWrapper class. Strangely enough, this setting effectively centers my Login class horizontally. Even when zooming out significantly, the alignment remains consistent. Experimentation with different percentage values has yielded results that defy traditional expectations.
I have tested this across various browsers, consistently obtaining the same outcome.
Could someone shed light on what exactly is happening here?
