Je suis sûr que vous auriez déjà trouvé votre réponse... voici la solution à laquelle j'ai abouti.
C'est mon CSS.
.field, .actions {
margin-bottom: 15px;
}
.field label {
float: left;
width: 30%;
text-align: right;
padding-right: 10px;
margin: 5px 0px 5px 0px;
}
.field input {
width: 70%;
margin: 0px;
}
Et mon HTML...
<h1>New customer</h1>
<div class="container form-center">
<form accept-charset="UTF-8" action="/customers" class="new_customer" id="new_customer" method="post">
<div style="margin:0;padding:0;display:inline"></div>
<div class="field">
<label for="customer_first_name">First name</label>
<input class="form-control" id="customer_first_name" name="customer[first_name]" type="text" />
</div>
<div class="field">
<label for="customer_last_name">Last name</label>
<input class="form-control" id="customer_last_name" name="customer[last_name]" type="text" />
</div>
<div class="field">
<label for="customer_addr1">Addr1</label>
<input class="form-control" id="customer_addr1" name="customer[addr1]" type="text" />
</div>
<div class="field">
<label for="customer_addr2">Addr2</label>
<input class="form-control" id="customer_addr2" name="customer[addr2]" type="text" />
</div>
<div class="field">
<label for="customer_city">City</label>
<input class="form-control" id="customer_city" name="customer[city]" type="text" />
</div>
<div class="field">
<label for="customer_pincode">Pincode</label>
<input class="form-control" id="customer_pincode" name="customer[pincode]" type="text" />
</div>
<div class="field">
<label for="customer_homephone">Homephone</label>
<input class="form-control" id="customer_homephone" name="customer[homephone]" type="text" />
</div>
<div class="field">
<label for="customer_mobile">Mobile</label>
<input class="form-control" id="customer_mobile" name="customer[mobile]" type="text" />
</div>
<div class="actions">
<input class="btn btn-primary btn-large btn-block" name="commit" type="submit" value="Create Customer" />
</div>
</form>
</div>
