HTML Markup#

Do you prefer to use HTML instead of a web component? No problem, use the markup below along with CSS.

Forms can be tricky, so here is some guidance around how to implement accessibility successfully.

<div class="gr-form-element">    <label class="gr-label" for="selectOne">I am a select box</label>    <div class="gr-select-container">        <select class="gr-select" id="selectOne">            <option value="one">Option One</option>            <option value="two">Option Two</option>        </select>        <svg focusable="false" class="icon-18" aria-hidden="true">            <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#drop-down-18"></use>        </svg>    </div>    <div class="error-state">        <svg focusable="false" class="icon-18" aria-hidden="true">            <use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#warning-18"></use>        </svg>        <span class="gr-meta">Warning Text</span>    </div></div>
