Propriedade Border
Borda CSS
Nosso atributo CSS favorito, permite que você personalize completamente as bordas que aparecem em torno dos elementos HTML. Com o HTML, costumava ser impossível colocar uma borda em torno de um elemento, exceto a tabela. As bordas de CSS permitem criar estilos de borda nítidos e personalizados com muito pouco trabalho, em comparação com os métodos antiquados de HTML.
A propriedade abreviada de border define todas as propriedades da borda em uma declaração. `` `css borda: 1px sólido # 000;
The properties that can be set, are (in order):
1. `border-style`
2. `border-width`
3. `border-color`
4. `border-radius`
It does not matter if one of the values above are missing, for example:
css borda: vermelho sólido;
The above code is also valid CSS.
### Border Styles
The `border-style` property sets a wide range of different types of borders.
The various values are:
- `dotted` - Sets a dotted border.
- `dashed` - Sets a dashed border.
- `solid` - Sets a solid border.
- `double` - Sets a double border.
- `groove` - Sets a 3D grooved border.
- `ridge` - Sets a 3D ridged border.
- `inset` - Sets a 3D inset border.
- `outset` - Sets a 3D outset border.
- `none` - Sets no border.
- `hidden` - Sets a hidden border.
Based on the property you choose, these styles can be mismatched.
You can style each side seperately:
css border-top-style: sólido; border-left-style: pontilhado; border-right-style: tracejado; border-bottom-style: duplo;
Or you can style them all at once:
css estilo de borda: sólido pontilhado duplo;
As shown, the border property allows you to select different sections of it. [top, bottom, left, right]
### Border Width
To alter the thickness of your border use the border-width attribute. You may use key terms or exact values to define the border width. Note: You must
define a border-style for the border to show up. The width can be set as a specific size (in px, pt, cm, em, etc) or by using one of the three pre-defined
values: thin, medium, or thick.
Example:
css
table { border-width: 7px; border-style: outset; } td { border-width: medium; border-style: outset; } p { border-width: thick; border-style: solid; }
### Border Color
Now for the creative aspect of CSS Borders! With the use of the border-color attribute, you will be able to create customized borders to fit the flow and layout
of your website. Border colors can be any color defined by RGB, hexadecimal, or key terms. Below is an example of each of these types.
Example:
css
table { border-color: rgb( 100, 100, 255); border-style: dashed; } td { border-color: #FFBD32; border-style: ridge; } p { border-color: blue; border-style: solid; }
### Border-Radius
The `border-radius` property allows the corners of a border to be rounded. This is done by providing a size for
how much the border is to be rounded. Size can be in px or %.
css raio de fronteira: 25 px;
Each corner of `border-radius` can be adjusted. The order is top, bottom, left, right.
css raio de fronteira: 15% 10px 30% 5px;
### Border: All in One
While it is nice that CSS allows a web developer to be very specific in creating a customized border, sometimes it is just easier and less of a headache to create a uniform border, all in single line of CSS code.
Example:
css
p { border: 20px outset blue; } h4 { border: 5px solid; } h5 { border: dotted; }
