What is the general rule about overriding styles in css with examples?
More specific css targets override more generic ones. E.g.
* A generic border property will be overridden by a specific border property.
* Styles applied to a class will override generic html tag styles.
* Any specific css will override the default browser css.
What is the difference between ID and Class selectors for CSS?
- IDs are unique. Only one element will have an ID.
- An element can also only have one ID.
- Classes can be applied to multiple elements.
What is a pseudo class and example of style for one?
Its the state of an element e.g. :hover.
a:hover{
color:black
}
What are four main display values and how do they work?
display:inline;
* This is one where it does not block out the whole line.
* Adding a nother element will add it next to it if both are inline.
* You can’t set the size e.g. height and width of in-line elements. It fills the space it needs.
display:block;
* This is the one where it blocks out the whole width.
* Adding another element will move it to the next line.
* This is the default for most elements.
display:block-inline
* This is a halfway point between in-line and block.
* You can use the “inline” aspect by letting elements sit next to each other.
* You can use the “block” aspect to set its size.
* The items will sit next to each other.
display:none
* Makes an item disappear.
What is best practice?
float:left; vs display:inline; vs display:inline-block; vs display:table-cell;
https://stackoverflow.com/questions/11805352/floatleft-vs-displayinline-vs-displayinline-block-vs-displaytable-cell/11823622#11823622
Short answer is that display:inline-block is the better option.
In modern web design we’ll use flexbox, grid, bootstrap etc. Use float only for wrapping text.
What is CSS float, how can it be used and what is clear?
- The float CSS property places an element on the left or right side of its container
- The main idea is to wrap text around something. So think about the layout of a newspaper.
- The columns can go next to each other with the
display:block-inlineand the text can wrap around images with thefloat:leftproperty. - In this example you can make the image float left and the paragraph will fill the space around it.
What if you dont want the paragrapgs to flow around it, like a footer
* Setting the the clear:left property on an element will make it ignore any floats. it is “cleared” of the left float. or also clear:both.
Write an example of a media query that sets the font size of an H1 for screens smaller than 600px and larger than 900px;
@media (max-width: 600px) and (min-width:900px){
h1{
font-size: 15px;
}}What should table layout be used for today?
Any tabular data. Dont want to use tables for layout anymore. Its not good for compatibility and accessibility.
What does display:inline-block; do and what is the challenge?
It will let all the divs you apply it to show up on the same line.
The challenge is that they wont be the same heights and will require more stiling to get the layout perfect.
What is position absolute?
It will take elements out of the normal flow of HTML, but its a ridgit way to do layout. if you add more things that arent absolute the layout won’t work well.
What is the challenge with using float layout and when is it appropriate?
You require a lot of hacks to make things work with the float layout. Best practice is to use it as it was intended to lat an image float next to text etc. for layout there are better options.
What does flexbox do?
It is used to create page layouts.
