How to line up flex box columns beside eachother - html

Question

I am trying to line up 3 different columns under the same class using flexbox.
But when i enter the HTML on my browser, all the content in the different containers are lined in a single line from top too bottom, instead of having the columns beside each other from left to right, and the items inside goes from top to bottom.
Here is the relevant part of the HTML code(all inside the body tag.)
<div class="container">
<article class="text item">
<a href="https://www.foxnews.com/category/person/joe-biden">President
Biden</a> is set to meet with Ukrainian President Volodymyr Zelensky
at the White House on Wednesday – a visit that is expected to build on
and amplify the bilateral relationship, and to underscore the United
States’ "ironclad" commitment to Ukraine’s security and sovereignty,
senior administration officials said.

<p class="text item">
The two leaders have spoken twice by phone – once in April, and once in
June before <a href="https://www.shorturl.at/puMQX">Biden met with
Russian President Vladimir Putin in Geneva</a>.
</p>
<p class="text item">
Senior administration officials said Biden and Zelensky will chair an
expanded bilateral meeting with their key advisers, and will later
transition to a one-on-one conversation, giving them "the space to
communicate with one another more directly."

Officials said Biden will convey his <em>"ironclad commitment"</em> to
Ukraine’s security, sovereignty and Euro-Atlantic aspirations. Biden
is also expected to discuss the security situation that Ukraine is
facing, as the nation continues to see <a href="#">acts of Russian
aggression</a> in the region.
</p>
<p class="text items">
Biden also will discuss ways in which the U.S. could continue to provide
security assistance to Ukraine, officials said – noting that the U.S
. will provide a new $60 million security assistance package for Ukraine
that will include additional Javelin anti-armor systems and other
defensive lethal and non-lethal capabilities.
</p>
<p class="text items">
So far, the U.S. has committed $2.5 billion in support of Ukraine forces
since 2014, including more than $400 million in 2021 alone.
</p>
<p class="text items">
As for reform, Biden is set to discuss the ways in which Ukraine has made
"progress on governance, rule of law, and anti-corruption reforms since
2014." Biden, while serving as vice president for former President
Obama, was tasked with overseeing the administration’s Ukraine policy.
</p>
<p class="text items">
The president is also expected to discuss cooperation efforts to bolster
collaboration on shared energy and climate goals, including through a
reinvigorated Strategy Energy and Climate Dialogue, which officials say
would give a "strong" platform to "advance energy security objectives,
enhance economic ties, and achieve ambitious climate targets."
