title: How to set text width to column in Streamlit
body: <p>I just started creating an app with <code>Streamlit</code> and have a problem, that the text does not comply with container (column) width:</p>

  <pre class="lang-py prettyprint-override"><code>sequences = []
  labels = [&quot;first&quot;, &quot;second&quot;]
  with st.form(key=&quot;fasta_dropdown&quot;):
      f_cols = st.columns(2)
      for i, col in enumerate(f_cols):
          id = col.selectbox(
              f&quot;Select {labels[i]} FASTA&quot;, fasta_df[&quot;ID&quot;], key=i
          )
          seq = get_sequence_by_id(fasta_df, id)
          sequences.append(seq)
          with col.expander(label=&quot;View sequence&quot;):
              st.markdown(&quot;&quot;&quot;

              &quot;&quot;&quot;
              )
  
      dropdown_submit = st.form_submit_button(&quot;Apply sequences&quot;)
  </code></pre>
  <p>How can I fix that? Putting the text into <code>HTML</code> formatting with <code>style=&quot;width: 10%&quot;</code> does not change anything.</p>
