Error end tag of the template?

What the problem is the closing tag of the template that says that error
12 {% endfor%}
13 {% endblock main_sections%}
14 
15 {% block aside_news_sections%}
16 <h3> <b> 10 facts about your health </ b> </ h3>
17 <img src = "https://news.tut.by/society/640246.html" class = "img-thumbnail mb-1">
18 <p> When you begin to take care of your health, understand a lot. We present you 10 facts about your health </ p>
19 <a href="https://news.tut.by/society/640246.html" target="_blank">
20 <button class = "btn btn-warning"> View </ button>
21 </a>
22 {% endblock aside_news_sections%}

Solution
% block aside_news_sections%}

And brace where?
error when copied into the toaster, fixed, django swears by a closing tag {% endblock aside_news_sections%} - Gracie_Langworth commented on March 23rd 20 at 19:08
@Gracie_Langworth, try instead {% endblock aside_news_sections%} just {% endblock %} - lyda_Walter commented on March 23rd 20 at 19:11

12 {% endfor%}
13 {% endblock main_sections%}
14 
15 {% block aside_news_sections%}
16 <h3> <b> 10 facts about your health </ b> </ h3>
17 <img src = "https://news.tut.by/society/640246.html" class = "img-thumbnail mb-1">
18 <p> When you begin to take care of your health, understand a lot. We present you 10 facts about your health </ p>
19 <a href="https://news.tut.by/society/640246.html" target="_blank">
20 <button class = "btn btn-warning"> View </ button>

It is to hike there (22 string) specifies any error in the templates. I see above you have {% endblock main_sections%} - try also to {% endblock %} to change. - lyda_Walter commented on March 23rd 20 at 19:10
