Question: I have this code:

```html
<h1> Something </h1>
<h3> Somethings </h3>
<h3> Some other things </h3>
```

I think HTML would automatically add 1 line spacing in between them.
I would like them to just go without 1 line of spacing, line by line I mean, not line space line space.

How could I do this without using a `<br>` element which is definitely unworkable in between the `<h1>` and `<h3>`, and probably not a structurally good HTML practice maybe too right?

Is using a CSS bottom margin fix this?

I am sorry to ask such an easy question maybe, I am a still bit new to HTML & CSS, but I am still learning. Thx in advance for all the answers

Answer: 
**Default styling, the enemy of consistency**

Many elements have default margins applied to them by browsers. The problem is that each browser (Chrome, IE etc) applies different amounts of margin.

This makes it hard to achieve *consistency* between browsers, and consistency is what we need for effective web-design.

**CSS Resets to the rescue**

Look into the concept of "*CSS Resets*". Using this approach, and advisably some prebuilt code like this: <https://github.com/murtaugh/HTML5-Reset> will RESET these values to zero to give you a level playing field.

Then YOU can decide how much margin your headings will have.

The reset you are looking for here - just for this problem - is:

```
h1, h2, h3 {
 margin: 0px;
}

```

**Then applying your own styles**

Then you would build it back up again, like this for example:

```css
h1, h2, h3 {
 margin: 0px;
}

h1 {
 margin-bottom: 20px;
} 

h2, h3 {
 margin-bottom: 10px;
}
```

```html
<h1> Something </h1>
<h3> Somethings </h3>
<h3> Some other things </h3>
```

**The universal reset**

A very simple "total" CSS reset would be:

```
* {
 margin:0;
 padding:0;
}  

```

But that's not advisable for a number of reasons especially performance: [(why) is the CSS star selector considered harmful?](https://stackoverflow.com/questions/1714096/why-is-the-css-star-selector-considered-harmful)
Headings have a margin by default, so yes, you should use CSS to remove the margins.
