How to find element of username field using selenium driver
<p>i'm trying to find the username element with webdriver.
the webpage is developped with polymer
the html content is:</p>

<pre><code>&lt;gui-input class="flex style-scope login-window x-scope gui-input-0" id="username" icon="account-circle" label="Username" autofocus="" floating-label=""&gt;
</code></pre>

<p>With Selenium i tried this :</p>

<pre><code>driver.findElement(By.className("gui-input#username")).isDisplayed()
</code></pre>

<p>But it cannot find the username field.</p>

<p>Any help please.
