I want three articles to be displayed on the homepage of the desktop version, each article in its own column. As I'm using flexbox this should be done easily, as I read in some tutorials.
But nothing changes, the articles are still one under another. I tried with this tutorial: https://davidwalsh.name/flexbox-column

<h3>Belgian Food</h3>
<p>
Traditional Belgian food is not for the faint hearted, with dishes such as bloedworst (black pudding made from pig's blood, served with apple sauce), breugel kop (chunks of beef and tongue set in gelatine) and paar de filet/steack de cheval (horse
steak). But there are more elegant spins on the local fare available: try La Maison du Cygne, which fuses Belgian and French cuisine and also offers glorious views of Brussels' gabled, gilded Grand Place.

<h3>Waffles</h3>
<p>
Belgian waffles (gauffres) are internationally known, but in Belgium there are two different types: the Brussels waffle and the Liège waffle. The Brussels waffle is rectangular, golden brown on the outside, dusted with powdered/icing sugar and then
sometimes covered with syrup, slices of fruit, chocolate spread and whipped cream - all of which is deemed a mite inauthentic by waffle connoisseurs! The denser textured Liege waffle is square and has burnt sugar on the outside. They are sold
by street vendors and gourmet restaurants alike, all over Belgium.
