Use <form> as <div>

How do I use without applying any style? Kind of like using <div> with ng-submit.

In the example below, without using <form>, the display is fine, but using <form> would screw up the display of <label>, <button> and etc.

<div class="bar bar-header item-input-inset">
    <form ng-submit="search()">
        <label class="item-input-wrapper">
            <i class="icon ion-ios-search placeholder-icon"></i>
            <input type="search" placeholder="Search" ng-model="input.query"
                   ng-change="suggest()" show-android-keyboard>
        <button class="button button-clear button-positive"

My apology for a trivial question like this, but I couldn’t find a solution and my css sucks.
