Tableau adds subtle borders on hover to create contrast, but you can deliberately set a black bar border and lower its opacity (around 62%) to make bars pop off the page
Use balanced layout containers with blanks either side and padding top and bottom so nothing contests for space
Apply a slightly off-grey border to the layout container surrounding the content you want to emphasise
Change the dashboard background to a slightly off-grey while keeping the sheet white so the content stands apart from the page
Give the title a different, lighter shade of grey to create contrast across the whole visualisation

0:00Hey, Tim here. And welcome to this quick

0:02tip where I'm going to show you how to make

0:04content pop off the page.

0:06So what do I mean by pop? Well, Tableau

0:08does this automatically. It's essentially a

0:11trick that uses contrast to help you focus

0:13in on a particular part of the sheet.

0:15So in this example, I have a bar chart

0:17showing the countries and then the sales

0:20for each country ranked.

0:23When I hover over them, you can see that

0:25Tableau adds a very, very thin border

0:28around the bar. And that has the effect of

0:31helping you focus in on what you're doing

0:33and sort of focuses in on each of the bars.

0:36And it really helps with contrast. Now, if

0:38you were to zoom into one of these bars,

0:40you'd also notice there's probably also a

0:42much fainter sort of thin border going

0:44around.

0:45And that has the effect again of making the

0:47bars sit a bit above the page. Now, you can

0:49be more deliberate with this effect with

0:51bar charts by just simply going in and

0:52selecting black.

0:54And you can see straight away there that

0:55the bars are popping off the page a little

0:57bit. If I just go back, you can see it

0:59without and you can see it with.

1:02You can literally feel the content popping

1:04off the page. Now, what I'm going to do is

1:05make this effect a little bit more obvious

1:07by dropping the color down a little bit to

1:0962%.

1:11So you can much easily see the sort of

1:12border. Then I'm going to go to my example

1:15dashboard where this sheet has already been

1:17placed.

1:18Now, the thing is, this effect also works

1:20with layout. If you use this more generally

1:23in your layouts, it's much easier for the

1:25user to focus in on what you want them to

1:27see.

1:28So in this case, what I've done is I've put

1:29some layout containers. I've put in one at

1:32the top and one at the bottom. These

1:34essentially are just giving me some padding

1:37.

1:37In this middle one, which I'll show you now

1:39, I've put three things. A blank on the

1:41right, a blank on the left, and a sheet in

1:44the middle which is actually inside its own

1:47layout container.

1:49So everything is balanced in an equilibrium

1:51here. Everything is nicely spaced out and

1:54nothing is contesting for space. And the

1:56thing I want you to look at is in the

1:57middle.

1:58So you might think, well, that's my job

2:00done. Well, there's actually more you can

2:02do here and it's very, very simple. First

2:04of all, start by selecting the layout

2:06container surrounding the content that you

2:08want to focus in on.

2:10Having done that, go and format it. And

2:13then what you can do is you can change two

2:15things. You can either change the

2:17formatting of the layout container, so the

2:19color inside the layout container, or you

2:21can just change the border.

2:23So I'm going to just change the border.

2:25What I'm going to do is I'm going to choose

2:27a slightly off sort of gray. When I click

2:29out, you can see that's had the desired

2:32effect.

2:33But I'm actually not done yet. See, this is

2:34popping out the page. There's one last

2:36thing that's really fighting with the user

2:39here. And it's a very, very subtle thing.

2:42But the whole background is using the color

2:43white. But the sheet is also using the

2:45color white. And so you can help the user

2:47focus in on where the background is and

2:49where the content is by changing one of

2:50those two colors.

2:52So in this case, if I change the background

2:54to a slightly off gray, then you can see

2:57the effect works straight away. Now the

3:00chart is front and center in the middle.

3:04However, how much harder I try, I can't

3:05help but look at the sheet in the middle.

3:08And if you have multiple things on the page

3:10, it can really help you very quickly notify

3:12where the key sections of the chart are.

3:16If I change it to a slightly darker shade

3:17of gray, the effect still works. And it

3:19looks balanced. It looks very sort of well

3:21laid out. Now here at the top, you can see

3:23that the example sheet option has taken the

3:25same color as the background.

3:27So what I'm going to do is I'm going to

3:28format the title. And to play further with

3:31this effect, I'm actually going to give it

3:33a slightly lighter shade of gray.

3:35So I'm giving contrast across the whole

3:37visualization. And in three or four clicks,

3:39I've just literally elevated this very,

3:42very simple visualization into something

3:44that looks beautiful.

3:46And so that's it. That's a quick tip for

3:48this week. If you like it, please like the

3:50video, share it with your friends, and I'll

3:52see you in the next one.

Rollup

Contrast is what makes content visually pop off a page, and you can apply the same trick deliberately — to bars, to layout containers, and to whole dashboards — to draw the user's eye to what matters.

Tim starts with a simple ranked bar chart and an example dashboard where that sheet has already been placed, then builds up the contrast effect step by step.

The Breakdown

Why hover borders create pop 0:00

Tableau automatically adds a faint border around marks on hover, which lifts them visually above the page — that subtle contrast is the underlying trick worth noticing before you try to control it yourself.
Force black borders on bars 0:45

You can make the pop effect deliberate rather than accidental by setting a black border on your bars, then dropping its opacity (around 62%) so the border reads as a subtle lift rather than a hard outline.
Balance layouts with symmetric containers 1:18

Wrap the content you want to feature in its own layout container, flanked by blank containers on each side and padding containers above and below, so nothing else is competing for space around it.
Border the container, not just the mark 1:58

Once your layout is balanced, select the layout container around the content you want to emphasise and format its border to a slightly off-grey — this must come after the containers are laid out, since it's the container border that carries the contrast.
Separate background from sheet colour 2:42

If the dashboard background and the sheet are both plain white, they visually merge; changing the background to a slightly off-grey (while keeping the sheet white) makes the content stand apart, and this works with multiple sections on a page too.
Finish with title contrast 3:21

As a final touch, format the title in a different, lighter shade of grey than the background so contrast carries across the whole visualisation, not just the chart area.

Worth Knowing

The border/background colours used (black at 62% opacity, off-grey shades) are choices Tim demonstrates, not fixed rules — the principle is contrast, not a specific palette.
Getting the background-vs-sheet contrast right is described as very subtle, easy to overlook if both are left as default white.

Use It When

Reach for this when a dashboard or chart feels flat or unfocused and you want the viewer's eye drawn to a specific sheet or section without adding any new content.
