Can't select textbox in selenium
<p>I am trying to access the comment textbox in a generic huffington post artical. When I right click inspect element I get the following HTML code:</p>

<pre><code>&lt;div class="UFIInputContainer"&gt;
 &lt;div class="_1cb _5yk1"&gt;
  &lt;div class="_5yk2" tabindex="-2"&gt;
   &lt;div class="_5rp7"&gt;
</code></pre>

<p>with the line <code>&lt;div class="_1cb _5yk1"&gt;</code> highlighted.</p>

<pre><code>from selenium import webdriver
driver = webdriver.Chrome()
'''
Just pretend that I put in some code to log in to facebook
so I can actually post a comment on huffington post
'''
driver.get.('http://www.huffingtonpost.com/entry/worst-suicide-squad-reviews_us_57a1e213e4b0693164c34744?')
'''
Just a random artical about a movie
'''
comment_box = driver.find_element_by_css_selector('._1cb._5yk1')
'''
since this is a compound class I think I should use find_by_css_selector
'''
</code></pre>

<p>When I run this though, I get the error message: "no such element found". I have tried other methods of trying to get a hold of the comment textbox but I get the same error message and I am at a lost of how to access it. I am hoping somebody can shed some light on this problem.</p>

<p>edit: This is a more complete HTML code:</p>

<pre><code>&lt;html lang="en" id="facebook" class="svg "&gt;
 &lt;head&gt;...&lt;/head&gt;
  &lt;body dir="ltr" class="plugin chrome webkit win x1 Locale_en_US"&gt;
   &lt;div class="_li"&gt;
    &lt;div class="pluginSkinLight pluginFontHelvetica"&gt;
     &lt;div id="u_0_0"&gt;
      &lt;div data-reactroot class="_56q9"&gt;
       &lt;div class="_2pi8"&gt;
        &lt;div class="_491z clearfix"&gt;...&lt;/div&gt;
         &lt;div spacing="medium" class="_4uyl _1zz8 _2392 clearfix" direction="left"&gt;
          &lt;div class="_ohe lfloat"&gt;...&lt;/div&gt;
          &lt;div class&gt;
           &lt;div class="UFIInputContainer"&gt;
            &lt;div class="_1cb _5yk1"&gt;
             &lt;div class="_5yk2" tabindex="-2"&gt;
              &lt;div class="_5rp7"&gt;
             &lt;/div&gt;
            &lt;/div&gt;
            &lt;div class="UFICommentAttachmentButtons clearfix"&gt;...&lt;/div&gt;
            &lt;!-- react-empty: 39 --&gt;
            &lt;div class="_4uym"&gt;...&lt;/div&gt;
           &lt;/div&gt;
          &lt;/div&gt;
         &lt;/div&gt;
         ::after
