Several questions regarding header menu and blog-style …

Last week we opened a thread – unfortunately nobody replied. So new thread, new luck!
So please we are still looking forward to your replay/ support:

We have following requests regarding some changes on the Theme Enfold which we are using for our website. We are looking forward to your answer regarding the implementation possibilities:

(1) For our Menu-Item „Registrieren“ we would like to use the Button-Style „Button Style Colored“. But following problem appears: Button- and font color is the same (#2e3348) on our transparent header. Only by scrolling down the page the user is able to read the button text (font appears white). We would like to know, how to change the button font color in the transparent header into white without changing the color of the remaining menu-items?

(2) There are several terms on English: „Read more“, „by“ and the date desplay. For our German-speaking website we would like to exchange these terms with german ones. But on the other hand we would like to leave these terms for our English-speaking website (we use WPML to offer this service). Is this possiple?

(3) At the moment our links and words which are written in bold letters uses the same color (#96bdff). But actually we would like our bold written letters to appear in the same color as our „main content font color“ which is #2e3348. How can we manage this issue?

(4) Is it possible to define individually for each blog post the length of the excerpt? If yes, how?

(5) We don’t want to have those three dots at the end of the blog post excerpt. Rather we would like to define individually for each blog post which text we want to use for the excerpt. We have following standardised excerpt-form in mind:
– Headline
– bullet point 1
– bullet point 2
– bullet point 3
– Read more (en-Wesite)/ Mehr lesen (de-Website)

(6) For our Blog Presentation again we would like to have another style:
– left from the text a picture (1/4 of the page) which has approximately the same high as the whole passage.
– right from the picture the whole text (3/4 of the page): Blog-Headline, Date, Author, 3 bullet points and „Read more“ (en-Website) or „Mehr lesen“ (de-Website)

At the moment our blog-page displays only a tiny picture next to the Header which has approximately the same high of the header. And underneath you see an excerpt which include the first phrases from the blog post with those 3 dots at the end – and finaly the „Read more“.

We urgently need your feedback as our website should soon get launched.
Best regards,
Mihaela
