Cada apartado va en una columna diferente para que la página quede más clara.

Here apartado means section, part, or item of a text, form, page, or document.

So Cada apartado is each section or each item.

Depending on context, apartado can also mean things like:

• a section in a form
• a numbered part of a document
• a heading or subsection

It does not mean a physical apartment or room here.

Because cada is followed by a singular noun in Spanish.

So:

• cada apartado = each section
• cada página = each page
• cada columna = each column

Even though cada refers to multiple things overall, Spanish treats them one by one, so the noun stays singular.

Yes, va literally comes from ir = to go, but in Spanish it is also very common to use ir to mean:

• to go in
• to be placed in
• to belong in
• to be arranged in

So Cada apartado va en una columna diferente means something like:

• Each section goes in a different column
• Each section is placed in a different column
• Each section belongs in a different column

This is very natural in instructions, layout descriptions, recipes, labels, and similar contexts.

Because va and está give slightly different ideas.

• está en una columna diferente focuses on location: it is in a different column.
• va en una columna diferente focuses more on placement or arrangement: it goes in / should be in a different column.

In this sentence, the idea is about how the page is organized, so va en sounds more natural.

Because the sentence is talking about each section individually:

• Cada apartado = each section
• each one goes in one different column

So Spanish uses the singular:

• Cada apartado va en una columna diferente

It is not saying that one section goes into several columns. It is saying that each section has its own separate column.

Diferente means different.

So:

• una columna diferente = a different column

In Spanish, many adjectives normally come after the noun, and diferente usually does too.

Compare:

• una columna diferente = a different column
• una página clara = a clear page

This is the normal word order.

Because para que introduces a purpose clause with a conjugated verb.

Here:

• para que la página quede más clara

This means:

• so that the page becomes / ends up clearer
• in order for the page to be clearer

Use para when it is followed by an infinitive:

• para mejorar la página = to improve the page

Use para que when there is a new clause with its own verb:

• para que la página quede más clara

Because after para que, Spanish normally uses the subjunctive.

So:

• quede = present subjunctive of quedar
• queda = present indicative

The structure is:

• para que + subjunctive

Examples:

• Te lo explico para que lo entiendas.
• Lo organizamos así para que sea más fácil.
• Cada apartado va en una columna diferente para que la página quede más clara.

This is one of the most important patterns in Spanish.

Here quedar means something like:

• to end up
• to turn out
• to be left
• to look / seem after a change

So para que la página quede más clara means:

• so that the page ends up clearer
• so that the page looks clearer
• so that the page is easier to read visually

It suggests the page becomes clearer as a result of putting each section in a different column.

Yes, but the meaning changes slightly.

• para que la página sea más clara
  = so that the page is clearer
  This is possible and fairly neutral.

• para que la página esté más clara
  = so that the page is clearer
  This is less natural here, unless you mean a temporary state.

• para que la página quede más clara
  = so that the page ends up clearer / looks clearer after arranging it this way

In this sentence, quede is especially good because it emphasizes the result of the layout choice.

Because Spanish often uses the definite article when talking about a specific thing that is already understood from context.

Here la página means:

• the page in question
• the page being designed or discussed

Spanish uses articles more often than English in some cases, so la página sounds normal and natural.

Because clara agrees with página, which is a feminine singular noun.

• la página → feminine singular
• clara → feminine singular adjective

So:

• la página quede más clara

If the noun were masculine, you would use claro:

• el texto quede más claro

Here it means clearer in the sense of easier to understand or visually clearer, not brighter.

Claro/a can mean:

• clear
• understandable
• easy to see or read

In a page-layout context, más clara usually means:

• better organized
• less confusing
• easier for the reader to follow

Because Spanish often uses the present tense to describe:

• general truths
• instructions
• layout rules
• how something is normally organized

So Cada apartado va en una columna diferente can sound like:

• Each section goes in a different column
• Each section should go in a different column
• Each section is placed in a different column

And quede is the present subjunctive because it follows para que.

Yes. Even though it is grammatically a statement, it can easily sound like an instruction or design guideline.

Depending on context, it may mean:

• Each section goes in a different column
• Each section should go in a different column
• Put each section in a different column

Spanish often uses the present tense this way in explanations and instructions.

Yes, several things:

1. cada + singular noun

   • cada apartado

2. ir en to mean to go in / be placed in

   • va en una columna

3. para que + subjunctive for purpose

   • para que la página quede...

4. quedar + adjective to express the result of a change

   • quede más clara

These are all very common and useful patterns in everyday Spanish.
