[html] Best way to style a TextBox in CSS

I would like to hear what's the best thing to do with pure CSS.

The Situation:

I'm having a textbox in which i can search for specific items. Yet now i'm also having an advanced search with almost the same textbox yet the width of the advancedSearchTextbox is less than the default one.

My Question

What is the best way to style the textbox?

My Solution

I've fixed this now like this:

.defaultTextBox {
    padding: 0;
    height: 30px;
    position: relative;
    left: 0;
    outline: none;
    border: 1px solid #cdcdcd;
    border-color: rgba(0,0,0,.15);
    background-color: white;
    font-size: 16px;
}
.advancedSearchTextbox {
    width: 526px;
    margin-right: -4px;
}

and then in the HTML it'd look something like this for the advancedSearchTextbox:

<input type="text" class="defaultTextBox advancedSearchTextBox" />

Is this the best way to do it? Or are there any other options available? As for just 1 other textbox it's do-able but what if i need more textboxes on other pages?

Thanks in advance :)!

You Also wanna put some text (placeholder) in the empty input box for the

.myClass {_x000D_
   ::-webkit-input-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
   ::-moz-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
  /* firefox 19+ */_x000D_
   :-ms-input-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
  /* ie */_x000D_
  input:-moz-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
}

<input type="text" class="myClass" id="fname" placeholder="Enter First Name Here!">

user to understand what to type.

your approach is pretty good...

.myclass {_x000D_
    height: 20px;_x000D_
    position: relative;_x000D_
    border: 2px solid #cdcdcd;_x000D_
    border-color: rgba(0, 0, 0, .14);_x000D_
    background-color: AliceBlue;_x000D_
    font-size: 14px;_x000D_
}

<input type="text" class="myclass" />

You can use:

input[type=text]
{
 /*Styles*/
}

Define your common style attributes inside this. and for extra style you can add a class then.
